      1.1 跨数据中心的双向复制

      +

      如下图, dtle支持MySQL间的双向复制, 其普遍场景是用于跨数据中心的数据双向同步.

      +

      +

      其中:

      +
        +
      • dtle 会对数据的回环状况进行判断, 不会重复传输同一事务.
        • +
      • dtle 在传输过程中维持数据的事务性, 对于数据源的事务产生的数据, 在数据目标端是以相同的事务方式进行回放. 对于双写的场景, 目标端不会受到不完整的事务的影响.
        • +
      • dtle 在数据链路上, 可使用压缩/限速等功能, 更适合于跨数据中心的场景.

        1.2 公有云间的数据同步

        +

        dtle 可用于公有云间的数据同步, 可支持的部署方式同 1.0 和 1.1 两节介绍的方式. 其中的不同之处在于:

        +
          +
        • dtle 可部署于公有云的云主机服务上
          • +
        • dtle 对公有云上RDS服务给予的权限进行了适配, 不需高权限即可实现数据复制
          • +
        • dtle 对公有云的 MySQL 非官方版 进行了适配 (如阿里云RDS会增加隐式主键列, 导致 binlog中的数据与表结构不符)
          • +
        +

        目前支持的公有云同步通道:

        +
          +
        • 阿里云 -> 京东云
          • +

          1.3 MySQL到Kafka的数据变更通知

          +

          如下图, dtle支持MySQL到Kafka的数据变更通知, 其普遍场景是:

          +
            +
          • 当数据变更时, 通知 缓存件 进行缓存刷新
            • +
          • 当数据变更时, 通知 数据后处理件 进行数据扫描
            • +

            +

            如下图, dtle支持Oracle到MySQL的数据同步通知, 其场景是:

            +
              +
            • 当Oracle执行DDL时, 同步库/表结构到MySQL
              • +
            • 当Oracle执行DML时，同步字段变更到MySQL

              HTTP API、nomad 命令行工具 和 Web界面

              +

              HTTP API

              +

              curl命令实际上是调用nomad agent端的HTTP接口，将本地的job.json提交到nomad agent端。

              +
              curl -XPOST "http://127.0.0.1:4646/v1/jobs" -d @job.json -s | jq
+

              dtle rpm安装包提供了json和hcl格式的job样例。

              +

              jq

              +

              jq是一款格式化、提取json内容的工具。一般需使用Linux包管理器安装。

              +

              典型用法

              +
              # 格式化json内容：
+some_command_print_json | jq
+
+# 提取字段（Status）：
+some_command_print_json | jq '.Status'
+

              具体参考 https://stedolan.github.io/jq/tutorial/

              +

              nomad 命令行工具

              +

              此外还可以使用nomad命令行工具。nomad将命令行工具和agent端放在了同一个可执行文件中。

              +

              使用 nomad 命令行工具运行job, 使用hcl格式:

              +
              nomad job run -address="http://192.168.1.1:4646" job1.hcl
+# 或
+export NOMAD_ADDR="http://192.168.1.1:4646"
+nomad job run job1.hcl
+

              该用法本质上是对HTTP API的封装。

              +

                            以下步骤以docker容器的方式快速演示如何搭建Oracle到MySQL的单向复制环境.

                            +

                            创建网络

                            +
                            docker network create dtle-net
+

                            创建源端 Oracle

                            +
                              # 启动oracle镜像

+

                            创建目标端 MySQL

                            +
                            docker run --name mysql-dst -e MYSQL_ROOT_PASSWORD=pass -p 33061:3306 --network=dtle-net -d mysql:5.7 --gtid-mode=ON --enforce-gtid-consistency=1 --log-bin=bin --server-id=1
+

                            检查是否联通:

                            +
                            > mysql -h 127.0.0.1 -P 33061 -uroot -ppass -e "select @@version\G"

                                      在3.21.10.0以前，dtle回放时会设置set @@foreign_key_checks=OFF。外键的级连操作（如on update cascade）将无法生效。

                                      +

                                      从3.21.10.0开始，dtle增量回放时，默认set @@foreign_key_checks=ON。可以触发外键级连操作。

                                      +

                                      对于存在外键关系的一系列表，需要这些表在同一个job的复制范围内，才能正常执行。

                                      +

                                      该行为可用job配置中dest部分ForeignKeyChecks控制，默认为true。如有必要，可将其设为false。

                                      +

                                      涉及外键引用父表的事务，回放时会单独回放，不能并行。

                                      +

                                      遗留问题：在外键子表上alter table drop foreign key后，原外键父表依然会被认为是外键父表。

                                              如何搭建DTLE的监控系统

                                              +

                                              背景：

                                              +

                                              虽然在DTLE的文档里提供各种监控项的介绍，但是对于不熟悉prometheus和grafana配置的同学来说上手还是有些难度的。今天我就来DTLE 3.21.07.0来搭建一个DTLE的监控系统。

                                              +

                                              一、搭建DTLE运行环境

                                              +
                                                +
                                              • 配置两个节点的DTLE集群来演示,其拓扑如下:
                                                • +
                                              +

                                              topu

                                              +

                                              在修改DTLE配置文件的时候需要注意以下两点：

                                              +
                                                +
                                              1. 开启DTLE的监控，确保publish_metrics的值为ture

                                                                  +

                                                                  +

                                                                  +

                                                                  +

                                                                  +

                                                                  +

+set global binlog_transaction_dependency_tracking = WRITESET;
+-- will take effect for new session

                                                                  +

                                                                  此后MySQL生成的binlog中将附带TX依赖信息，dtle回放时可以利用依赖信息进行调度。

                                                                  +

                                                                  在dtle dest task config中设置ParallelWorkers，控制增量并行回放线程数。参考值为8～64。

                                                                  +

                                                                  如果因版本和权限问题，不能在源端MySQL上设置WriteSet Tracking，则可以使用dtle的依赖计算功能（UseMySQLDependency = false）。

                                                                  +

                                                                  批量插入（bulk insert）

                                                                  +

                                                                  当源端使用批量插入，即 insert into ... values (),(), ..., () 时，dtle会在目标端使用批量插入。

                                                                  +

                                                                  dtle会使用两个固定数量（行数）的批量插入PreparedStatement，默认为4和8。超过8的会被分到下一批。小于4的会单独插入。

                                                                  +

                                                                  + + +

                                                                        +

                                                                        +

                                                                        +

                                                                        通过swagger UI查看接口文档

                                                                        +

                                                                        访问http://{dtle ip}:8190/swagger/index.html通过swagger UI查看接口文档，打开界面如下：

                                                                        +

                                                                        +

                                                                        通过swagger UI调用API

                                                                        +

                                                                        除了使用curl命令外，还可以通过swagger UI界面调用API，具体步骤如下：

                                                                        +

                                                                        1 点击"Try it out"，进入调试模式

                                                                        +

                                                                        +

                                                                        2 填写请求参数后点击"Execute"调用API

                                                                        +

                                                                        +

                                                                        3 查看响应：

                                                                        +

                                                                        +

                                                                        4 由于用户校验功能限制，大多数接口调用需要在header中携带登录成功返回的token，在swagger页面可点击swagger页面顶部的Authorize按钮，将token填入Value的文本框中，swagger页面中其他接口即可正常使用

                                                                        +

                                                                        +

                                                                        dtle API Docs

Grants + +Each Contributor hereby grants You a world-wide, royalty-free, +non-exclusive license: + +(a) under intellectual property rights (other than patent or trademark) + Licensable by such Contributor to use, reproduce, make available, + modify, display, perform, distribute, and otherwise exploit its + Contributions, either on an unmodified basis, with Modifications, or + as part of a Larger Work; and + +(b) under Patent Claims of such Contributor to make, use, sell, offer + for sale, have made, import, and otherwise transfer either its + Contributions or its Contributor Version. + +2.2. Effective Date + +The licenses granted in Section 2.1 with respect to any Contribution +become effective for each Contribution on the date the Contributor first +distributes such Contribution. + +2.3. Limitations on Grant Scope + +The licenses granted in this Section 2 are the only rights granted under +this License. No additional rights or licenses will be implied from the +distribution or licensing of Covered Software under this License. +Notwithstanding Section 2.1(b) above, no patent license is granted by a +Contributor: + +(a) for any code that a Contributor has removed from Covered Software; + or + +(b) for infringements caused by: (i) Your and any other third party's + modifications of Covered Software, or (ii) the combination of its + Contributions with other software (except as part of its Contributor + Version); or + +(c) under Patent Claims infringed by Covered Software in the absence of + its Contributions. + +This License does not grant any rights in the trademarks, service marks, +or logos of any Contributor (except as may be necessary to comply with +the notice requirements in Section 3.4). + +2.4. Subsequent Licenses + +No Contributor makes additional grants as a result of Your choice to +distribute the Covered Software under a subsequent version of this +License (see Section 10.2) or under the terms of a Secondary License (if +permitted under the terms of Section 3.3). + +2.5. Representation + +Each Contributor represents that the Contributor believes its +Contributions are its original creation(s) or it has sufficient rights +to grant the rights to its Contributions conveyed by this License. + +2.6. Fair Use + +This License is not intended to limit any rights You have under +applicable copyright doctrines of fair use, fair dealing, or other +equivalents. + +2.7. Conditions + +Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted +in Section 2.1. + +3. Responsibilities +------------------- + +3.1. Distribution of Source Form + +All distribution of Covered Software in Source Code Form, including any +Modifications that You create or to which You contribute, must be under +the terms of this License. You must inform recipients that the Source +Code Form of the Covered Software is governed by the terms of this +License, and how they can obtain a copy of this License. You may not +attempt to alter or restrict the recipients' rights in the Source Code +Form. + +3.2. Distribution of Executable Form + +If You distribute Covered Software in Executable Form then: + +(a) such Covered Software must also be made available in Source Code + Form, as described in Section 3.1, and You must inform recipients of + the Executable Form how they can obtain a copy of such Source Code + Form by reasonable means in a timely manner, at a charge no more + than the cost of distribution to the recipient; and + +(b) You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter + the recipients' rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + +You may create and distribute a Larger Work under terms of Your choice, +provided that You also comply with the requirements of this License for +the Covered Software. If the Larger Work is a combination of Covered +Software with a work governed by one or more Secondary Licenses, and the +Covered Software is not Incompatible With Secondary Licenses, this +License permits You to additionally distribute such Covered Software +under the terms of such Secondary License(s), so that the recipient of +the Larger Work may, at their option, further distribute the Covered +Software under the terms of either this License or such Secondary +License(s). + +3.4. Notices + +You may not remove or alter the substance of any license notices +(including copyright notices, patent notices, disclaimers of warranty, +or limitations of liability) contained within the Source Code Form of +the Covered Software, except that You may alter any license notices to +the extent required to remedy known factual inaccuracies. + +3.5. Application of Additional Terms + +You may choose to offer, and to charge a fee for, warranty, support, +indemnity or liability obligations to one or more recipients of Covered +Software. However, You may do so only on Your own behalf, and not on +behalf of any Contributor. You must make it absolutely clear that any +such warranty, support, indemnity, or liability obligation is offered by +You alone, and You hereby agree to indemnify every Contributor for any +liability incurred by such Contributor as a result of warranty, support, +indemnity or liability terms You offer. You may include additional +disclaimers of warranty and limitations of liability specific to any +jurisdiction. + +4. Inability to Comply Due to Statute or Regulation +--------------------------------------------------- + +If it is impossible for You to comply with any of the terms of this +License with respect to some or all of the Covered Software due to +statute, judicial order, or regulation then You must: (a) comply with +the terms of this License to the maximum extent possible; and (b) +describe the limitations and the code they affect. Such description must +be placed in a text file included with all distributions of the Covered +Software under this License. Except to the extent prohibited by statute +or regulation, such description must be sufficiently detailed for a +recipient of ordinary skill to be able to understand it. + +5. Termination +-------------- + +5.1. The rights granted under this License will terminate automatically +if You fail to comply with any of its terms. However, if You become +compliant, then the rights granted under this License from a particular +Contributor are reinstated (a) provisionally, unless and until such +Contributor explicitly and finally terminates Your grants, and (b) on an +ongoing basis, if such Contributor fails to notify You of the +non-compliance by some reasonable means prior to 60 days after You have +come back into compliance. Moreover, Your grants from a particular +Contributor are reinstated on an ongoing basis if such Contributor +notifies You of the non-compliance by some reasonable means, this is the +first time You have received notice of non-compliance with this License +from such Contributor, and You become compliant prior to 30 days after +Your receipt of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent +infringement claim (excluding declaratory judgment actions, +counter-claims, and cross-claims) alleging that a Contributor Version +directly or indirectly infringes any patent, then the rights granted to +You by any and all Contributors for the Covered Software under Section +2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all +end user license agreements (excluding distributors and resellers) which +have been validly granted by You or Your distributors under this License +prior to termination shall survive termination. + +************************************************************************ +* * +* 6. Disclaimer of Warranty * +* ------------------------- * +* * +* Covered Software is provided under this License on an "as is" * +* basis, without warranty of any kind, either expressed, implied, or * +* statutory, including, without limitation, warranties that the * +* Covered Software is free of defects, merchantable, fit for a * +* particular purpose or non-infringing. The entire risk as to the * +* quality and performance of the Covered Software is with You. * +* Should any Covered Software prove defective in any respect, You * +* (not any Contributor) assume the cost of any necessary servicing, * +* repair, or correction. This disclaimer of warranty constitutes an * +* essential part of this License. No use of any Covered Software is * +* authorized under this License except under this disclaimer. * +* * +************************************************************************ + +************************************************************************ +* * +* 7. Limitation of Liability * +* -------------------------- * +* * +* Under no circumstances and under no legal theory, whether tort * +* (including negligence), contract, or otherwise, shall any * +* Contributor, or anyone who distributes Covered Software as * +* permitted above, be liable to You for any direct, indirect, * +* special, incidental, or consequential damages of any character * +* including, without limitation, damages for lost profits, loss of * +* goodwill, work stoppage, computer failure or malfunction, or any * +* and all other commercial damages or losses, even if such party * +* shall have been informed of the possibility of such damages. This * +* limitation of liability shall not apply to liability for death or * +* personal injury resulting from such party's negligence to the * +* extent applicable law prohibits such limitation. Some * +* jurisdictions do not allow the exclusion or limitation of * +* incidental or consequential damages, so this exclusion and * +* limitation may not apply to You. * +* * +************************************************************************ + +8. Litigation +------------- + +Any litigation relating to this License may be brought only in the +courts of a jurisdiction where the defendant maintains its principal +place of business and such litigation shall be governed by laws of that +jurisdiction, without reference to its conflict-of-law provisions. +Nothing in this Section shall prevent a party's ability to bring +cross-claims or counter-claims. + +9. Miscellaneous +---------------- + +This License represents the complete agreement concerning the subject +matter hereof. If any provision of this License is held to be +unenforceable, such provision shall be reformed only to the extent +necessary to make it enforceable. Any law or regulation which provides +that the language of a contract shall be construed against the drafter +shall not be used to construe this License against a Contributor. + +10. Versions of the License +--------------------------- + +10.1. New Versions + +Mozilla Foundation is the license steward. Except as provided in Section +10.3, no one other than the license steward has the right to modify or +publish new versions of this License. Each version will be given a +distinguishing version number. + +10.2. Effect of New Versions + +You may distribute the Covered Software under the terms of the version +of the License under which You originally received the Covered Software, +or under the terms of any subsequent version published by the license +steward. + +10.3. Modified Versions + +If you create software not governed by this License, and you want to +create a new license for such software, you may create and use a +modified version of this License if you rename the license and remove +any references to the name of the license steward (except to note that +such modified license differs from this License). + +10.4. Distributing Source Code Form that is Incompatible With Secondary +Licenses + +If You choose to distribute Source Code Form that is Incompatible With +Secondary Licenses under the terms of this version of the License, the +notice described in Exhibit B of this License must be attached. + +Exhibit A - Source Code Form License Notice +------------------------------------------- + + This Source Code Form is subject to the terms of the Mozilla Public + License, v. 2.0.

3.21.07.0来搭建一个DTLE的监控系统。\n一、搭建DTLE运行环境\n\n配置两个节点的DTLE集群来演示,其拓扑如下:\n\n\n在修改DTLE配置文件的时候需要注意以下两点：\n\n开启DTLE的监控，确保publish_metrics的值为ture\n开启nomad的监控，确保正确配置telemetry\n\n这里以dtle-src-1的配置为例，具体配置参考节点配置:\n# DTLE 3.21.07.0中nomad升级为1.1.2，需要添加如下配置使nomad提供监控数据\n# 之前版本的DTLE无需添加此配置\ntelemetry {\n prometheus_metrics = true\n collection_interval = \"15s\"\n}\n\nplugin \"dtle\" {\n config {\n data_dir = \"/opt/dtle/var/lib/nomad\"\n nats_bind = \"10.186.63.20:8193\"\n nats_advertise = \"10.186.63.20:8193\"\n # Repeat the consul address above.\n consul = \"10.186.63.76:8500\"\n\n # By default, API compatibility layer is disabled.\n api_addr = \"10.186.63.20:8190\" # for compatibility API\n nomad_addr = \"10.186.63.20:4646\" # compatibility API need to access a nomad server\n\n publish_metrics = true\n stats_collection_interval = 15\n }\n}\n\n添加两个job模拟两个MySQL实例之间传输数据\n\n\n\n二、部署prometheus\n\n准备prometheus配置文件同时接收nomad和DTLE的metrics\nDTLE监控labels:instance的值建议设置为DTLE服务器的hostname\n\nshell> cat /path/to/prometheus.yml\nglobal:\n scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.\n evaluation_interval: 15s # Evaluate rules every 15 seconds.

http://${prometheus_server_ip}:9090/targets 验证配置生效\n\n\n\n三、部署grafana\n\n利用docker部署grafana服务\nshell> docker run -d --name=grafana -p 3000:3000 grafana/grafana\n\n在浏览器上访问grafana的页面 http://${grafana_server_ip}:3000 ，使用默认用户 admin/admin登录\n\n配置添加数据源\n\n\n选择添加promethues\n\n\n只需将promethues的访问地址添加到URL中，点击“sava &

task需各自重复。默认值为 cpu=100，memory=300。\n以默认值建立大量轻量级任务，会导致资源不够而pending，可适当调小。\n任务的内存消耗和每行大小、事物大小、队列长度有关。注意真实资源消耗，避免OOM。\ntask \"src\" {\n resources {\n cpu = 100 # MHz\n memory = 300 # MB\n }\n}\nrestart &

意味着interval过后继续尝试\n # \"fail\" 则不再尝试\n}\nreschedule { # job or group level\n delay = \"30s\"\n delay_function = \"exponential\"\n max_delay = \"1h\"\n unlimited = true\n}\n\n当task报错时，会根据restart配置，30分钟内在同一节点上重启最多两次\n即使失败的job被stop -purge再重新添加，也需要根据restart参数重启 \n\n\n2次重启均失败后，会根据reschedule配置，在其他节点上执行\n\n为了避免无限reschedule带来的问题，dtle安装包提供的样例job配置中(/usr/share/dtle/scripts/example.job.*)，限制reschedule为每半小时1次:\nreschedule {\n attempts = 1\n interval = \"30m\"\n unlimited = false\n}\n# 或json格式\n\"Reschedule\": {\n \"Attempts\": 1,\n \"Interval\": 1800000000000,\n \"Unlimited\":

client节点上执行。当源端目标端MySQL之间网络延迟很大时，应在各个主机/机房设立nomad client，并限制 task 在本地节点上执行，以充分利用dtle的压缩传输。\nReplChanBufferSize\n默认60，增量事物队列数量。增大可以降低可能的空等，但同时会占用更多内存。\nChunkSize\n默认2000。全量复制时每次选取的行数。增大可以增加吞吐量，但同时会占用更多内存。\nGroupMaxSize & GroupTimeout\nGroupMaxSize默认值1，即每个事物立刻发送。增大后将等待数据量达到设定值再打包发送多个事务。\n可增加传输时压缩率，适合低带宽网络。\n设定GroupTimeout可避免数据量不足时等待过久。默认值100(毫秒)。一般设成略小于 ping RTT 的时间值。\n增量的并行回放（MTS）相关\n推荐使用MySQL 5.7.22+ 和 MySQL 8.0 GA 后引入的 WriteSet MTS。在源端MySQL设置\nset global transaction_write_set_extraction = XXHASH64;\nset global binlog_transaction_dependency_tracking = WRITESET;\n-- will take effect for new session\n\n此后MySQL生成的binlog中将附带TX依赖信息，dtle回放时可以利用依赖信息进行调度。\n在dtle dest task config中设置ParallelWorkers，控制增量并行回放线程数。参考值为8～64。\n如果因版本和权限问题，不能在源端MySQL上设置WriteSet Tracking，则可以使用dtle的依赖计算功能（UseMySQLDependency = false）。\n批量插入（bulk insert）\n当源端使用批量插入，即 insert into ... values (),(), ..., () 时，dtle会在目标端使用批量插入。\ndtle会使用两个固定数量（行数）的批量插入PreparedStatement，默认为4和8。超过8的会被分到下一批。小于4的会单独插入。\n可用BulkInsert1和BulkInsert2调整批量插入使用的数量。\n"},"4/4.3.2_job_sample.html":{"url":"4/4.3.2_job_sample.html","title":"4.3.2.Job示例","keywords":"","body":"Job
