v1.4.0 Release

Quick Start

Get a new Linux x86_64 CentOS 7.8 node. with nopass sudo & ssh access, then:

bash -c "$(curl -fsSL http://download.pigsty.cc/get)"   # get latest pigsty source
cd ~/pigsty && ./configure --download --non-interactive # pre-check and config templating 
./infra.yml                                             # install pigsty on current node

You can also download pigsty source & software packages with curl:

curl -SL https://github.com/Vonng/pigsty/releases/download/v1.4.0/pkg.tgz -o /tmp/pkg.tgz
curl -SL https://github.com/Vonng/pigsty/releases/download/v1.4.0/pigsty.tgz | gzip -d | tar -xC

Architecture

• Decouple system into 4 major categories: INFRA, NODES, PGSQL, REDIS, which makes pigsty far more clear and more extensible.
• Single Node Deployment = INFRA + NODES + PGSQL
• Deploy pgsql clusters = NODES + PGSQL
• Deploy redis clusters = NODES + REDIS
• Deploy other databases = NODES + xxx (e.g MONGO, KAFKA, ... TBD)

Accessibility

• CDN for mainland China.
• Get the latest source with bash -c "$(curl -fsSL http://download.pigsty.cc/get)"
• Download & Extract packages with new download script.

Monitor Enhancement

• Split monitoring system into 5 major categories: INFRA, NODES, REDIS, PGSQL, APP
• Logging enabled by default
  • now loki and promtail are enabled by default. with prebuilt loki-rpm
• Models & Labels
  • A hidden ds prometheus datasource variable is added for all dashboards, so you can easily switch different datasource simply by select a new one rather than modifying Grafana Datasources & Dashboards
  • An ip label is added for all metrics, and will be used as join key between database metrics & nodes metrics
• INFRA Monitoring
  • Home dashboard for infra: INFRA Overview
  • Add logging Dashboards : Logs Instance
  • PGLOG Analysis & PGLOG Session now treated as an example Pigsty APP.
• NODES Monitoring Application

Provisioning Enhancement

Now pigsty work flow works as this:

 infra.yml ---> install pigsty on single meta node
      |          then add more nodes under pigsty's management
      |
 nodes.yml ---> prepare nodes for pigsty (node setup, dcs, node_exporter, promtail)
      |          then choose one playbook to deploy database clusters on those nodes
      |
      ^--> pgsql.yml   install postgres on prepared nodes
      ^--> redis.yml   install redis on prepared nodes

infra-demo.yml = 
           infra.yml -l meta     +
           nodes.yml -l pg-test  +
           pgsql.yml -l pg-test +
           infra-loki.yml + infra-jupyter.yml + infra-pgweb.yml
 

• nodes.yml to setup & prepare nodes for pigsty
  • setup node, node_exporter, consul agent on nodes

How to upgrade from v1.1.1

There's no API change in 1.2.0.

You can still use old pigsty.yml configuration files (PG13).

For the infrastructure part. Re-execution of infra.yml will do most of the parts

As for the database. You can still use the existing PG13 instances. In-place upgrade to PG14 is quite
tricky especially when involving extensions such as PostGIS & Timescale. I would highly recommend
performing a database migration with logical replication.

The new playbook pgsql-migration.yml will make this a lot easier. It will create a series of
scripts which will help you to migrate your cluster with near-zero downtime.

v1.1.1 TimescaleDB upgrade and new Patroni Templates

Pigsty v.1.1.1

• Upgrade timescaledb from apache version to timescale version.
• Add a series of new patroni config templates.

The default value for timescaledb.license is apache rather than timescale as the doc describes #3718

Changes

• [ENHANCEMENT] replace timescaledb apache version with timescale version
• [ENHANCEMENT] upgrade prometheus to 2.30
• [ENHANCEMENT] add new patroni config templates
• [BUG FIX] now pg_exporter config dir's owner are {{ pg_dbsu }} instead of prometheus

What's new in patroni config tempaltes?

Now there are a series of pre-defined patroni config templates aims for different machine spec.

Conf Name	CPU	Mem	Disk
tiny	1	1GB	40GB
mini	2	4GB	100GB
small	4	8GB	200GB
medium	8	16GB	500GB
large	16	32GB	1TB
xlarge	32	64GB	2TB
oltp,crit,olap	64	400GB	4TB

How to upgrade from existing setup ?

How to upgrade to v1.1.1 from v1.0.0.
The major change in v1.1.1 is timescaledb. Which replace old apache license version with timescale license version

(reinstall & restart required)

You can failover with patroni, then perform the timescaledb upgrade.

systemctl stop patroni
yum remove -y timescaledb_13

[timescale_timescaledb]
name=timescale_timescaledb
baseurl=https://packagecloud.io/timescale/timescaledb/el/7/$basearch
