Changelog

1.8.6

The semantics of Cron inputs have changed slightly, each tick will now be a separate file unless the Overwrite flag is set to true, which will get you the old behavior. The name of the emitted file is now the timestamp that triggered the cron, rather than a static filename. Pipelines that use cron will need to be updated to work in 1.8.6. See the docs for more info. (#3509)
1.8.6 contains alpha support for a new kind of pipeline, spouts, which take no inputs and run continuously outputting (or spouting) data. Documentation and an example of spout usage will be in a future release. (#3531)
New debug commands have been added to pachctl to easily profile running pachyderm clusters. They are debug-profile debug-binary and debug-pprof. See the docs for these commands for more information. (#3559)
The performance of list-job has been greatly improved. (#3557)
pachctl undeploy now asks for confirmation in all cases. (#3535)
Logging has been unified and made less verbose. (#3532)
Bogus output in with --raw flags has been removed. (#3523, thanks to @mdaniel)
Fixes a bug in list-file --history that would cause it to fail with too many files. (#3516)
pachctl deploy is more liberal in what it accepts for bucket names. (#3506)
pachctl now respects Kubernetes auth when port-forwarding. (#3504)
Output repos now report non-zero sizes, the size reported is that of the HEAD commit of the master branch. (#3475)
Pachyderm will no longer mutate custom image names when there's no registry. (#3487, thanks to @mdaniel)
Fixes a bug that caused pod_patch and pod_spec to be reapplied over themselves. (#3484, thanks to @mdaniel)

1.8.5

New shuffle step which should improve the merge performance on certain workloads.

1.8.4

Azure Blob Storage block size has been changed to 4MB due to object body too large errors. (#3464)
Fixed a bug in --no-metrics and --no-port-forwarding. (#3462)
Fixes a bug that caused list-job to panic if the Reason field was too short. (#3453)

1.8.3

--push-images on create-pipeline has been replaced with --build which builds and pushes docker images. (#3370)
Fixed a bug that would cause malformed config files to panic pachctl. (#3336)
Port-forwarding will now happen automatically when commands are run. (#3340)
Fix bug where create-pipeline accepts names which Kubernetes considers invalid. (#3344)
Fix a bug where put-file would respond master not found for an open commit. (#3184)
Fix a bug where jobs with stats enabled and no datums would never close their stats commit. (#3355)
Pipelines now reject files paths with utf8 unprintable characters. (#3356)
Fixed a bug in the Azure driver that caused it to choke on large files. (#3378)
Fixed a bug that caused pipelines go into a loop and log a lot when they were stopped. (#3397)
ADDRESS has been renamed to PACHD_ADDRESS to be less generic. ADDRESS will still work for the remainder of the 1.8.x series of releases. (#3415)
The pod_spec field in pipelines has been revamped to use JSON Merge Patch (rfc7386) Additionally, a field, pod_patch has been added the the pipeline spec which is similar to pod_spec but uses JSON Patches (rfc6902) instead. (#3427)
Pachyderm developer names should no longer appear in backtraces. (#3436)

1.8.2

Updated support for GPUs (through device plugins).

1.8.1

Adds support for viewing file history via the --history flag to list-file (#3277, #3299).
Adds a new job state, merging which indicates that a job has finished processing everything and is merging the results together (#3261).
Fixes a bug that prevented s3 put-file from working (#3273).
atom inputs have been renamed to pfs inputs. They behave the same, atom still works but is deprecated and will be removed in 1.9.0 (#3258).
Removed message and description from put-file, they don't work with the new multi put-file features and weren't commonly used enough to reimplement. For similar functionality use start-commit (#3251).

1.8.0

Completely rewritten hashtree backend that provides massive performance boosts.
Single sign-on Auth via Okta.
Support for groups and robot users.
Support for splitting file formats with headers and footers such as SQL and CSV.

1.7.10

Adds put-file --split support for SQL dumps. (#3064)
Adds support for headers and footers for data types passed to --split such as CSV and the above mentioned SQL. (#3064)
Adds support for accessing previous versions of pipelines using the same syntax as is used with commits. I.e. pachctl inspect-pipeline foo^ will give the previous version of foo. (#3159)
Adds support in pipelines for additional Kubernetes primitives on workers, including: node selectors, priority class and storage requests and limits. Additionally there is now a field in the pipeline spec pod_spec that allows you to set any field on the pod using json. (#3169)

1.7.9

Moves garbage collection over to a bloom filter based indexing method. This greatly decreases the amount of memory that garbage collection requires, at the cost of a small probability of not deleting objects that should be. Garbage collection can be made more accurate by using more memory with the flag --memory passed to pachctl garbage-collect. (#3161)

1.7.8

Fixes multiple issues that could cause jobs to hang when they encountered intermittent errors such as network hiccups. (#3155)

1.7.7

Greatly improves the performance of the pfs FUSE implementation. Performance should be close to on par with the that of pachctl get-file. The only trade-off is that the new implementation will use disk space to cache file contents. (#3140)

1.7.6

Pachyderm's FUSE support (pachctl mount) has been rewritten. (#3088)
put-file requests that put files from multiple sources (-i or -r) now create a single commit. (#3118)
Fixes a bug that caused put-file to throw spurious warnings about URL formatted paths. (#3117)
Several fixes have been made to which user code runs as to allow services such as Jupyter to work out of the box. (#3085)
pachctl now has auth set-config and auth get-config commands. (#3095)

1.7.5

Workers no longer run privileged containers. (#3031) To achieve this a few modifications had to be made to the /pfs directory that may impact some user code. Directories under /pfs are now symlinks to directories, previously they were bind-mounts (which requires that the container be privileged). Furthermore there's now a hidden directory under /pfs called .scratch which contains the directories that the symlinks under /pfs point to.
The number of times datums are retries is now configurable. (#3033)
Fixed a bug that could cause Kubernetes errors to prevent pipelines from coming up permanently. (#3043, #3005)
Robot users can now modify admins. (#3049)
Fixed a bug that could permanently lock robot-only admins out of the cluster. (#3050)
Fixed a couple of bugs (#3045, #3046) that occurred when a pipeline was rapidly updated several times. (#3054)
restore now propagates user credentials, allowing it to work on clusters with auth turned on. (#3057)
Adds a debug-dump command which dumps running goroutines from the cluster. (#3078)
pachd now prints a full goroutine dump if it encounters an error. (#3103)

1.7.4

Fixes a bug that prevented image pull secrets from propagating through pachctl deploy. (#2956, thanks to @jkinkead)
Fixes a bug that made get-file fail on empty files. (#2960)
ListFile and GlobFile now return results leixcographically sorted. (#2972)
Fixes a bug that caused Extract to crash. (#2973)
Fixes a bug that caused pachd to crash when given a pipeline without a name field. (#2974)
Adds dial options to the Go client's connect methods. (#2978)

Fixes a bug that caused connections to leak in the vault plugin. (#3016)
Fixes a bug that caused incremental pipelines that are downstream from other pipelines to not run incrementally. (#3023)
Updates monitoring deployments to use the latest versions of Influx, Prometheus and Grafana. (#3026)
Fixes a bug that caused update-pipeline to modify jobs that had already run. (#3028)

1.7.3

Fixes an issue that caused etcd deployment to fail when using a StatefulSet. (#2929, #2937)
Fixes an issue that prevented pipelines from starting up. (#2949)

1.7.2

Pachyderm now exposes metrics via Prometheus. (#2856)
File commands now all support globbing syntax. I.e. you can do pachctl list-file ... foo/*. (#2870)
garbage-collect is now safer and less error prone. (#2912)
put-file no longer requires starting (or finishing) a commit. Similar to put-file -c, but serverside. (#2890)
pachctl deploy --dry-run can now output YAML as well as JSON. Special thanks to @jkinkead. (#2872)
Requirements on pipeline container images have been removed. (#2897)
Pachyderm no longer requires privileged pods. (#2887)
Fixes several issues that prevented deleting objects in degraded states. (#2912)
Fixes bugs that could cause stats branches to not be cleaned up. (#2855)
Fixes 2 bugs related to auth services not coming up completely. (#2843)
Fixes a bug that prevented pachctl deploy storage amazon from working. (#2863)
Fixes a class of bugs that occurred due to misuse of our collections package. (#2865)
Fixes a bug that caused list-job to delete old jobs if you weren't logged in. (#2879)
Fixes a bug that caused put-file --split to create too many goroutines. (#2906)
Fixes a bug that prevent deploying to AWS using an IAM role. (#2913)
Pachyderm now deploys and uses the latest version of etcd. (#2914)

1.7.1

Introduces a new model for scaling up and down pipeline workers. Read more.
It's now possible to run Pachyderm without workers needing access to the docker socket. (#2813)
Fixes a bug that caused stats enabled pipelines to get stuck in a restart loop if they were deleted and recreated. (#2816)
Fixes a bug that broke logging due to removing newlines between log messages. (#2852)
Fixes a bug that caused pachd to segfault when etcd didn't come up properly. (#2840)
Fixes a bug that would cause jobs to occasionally fail with a "broken pipe" error. (#2832)
pachctl version now supports the --raw flag like other pachctl commands. (#2817)
Fixes a bug that caused max_queue_size to be ignored in pipelines. (#2818)

1.7.0

Implements a new algorithm for triggering jobs in response to new commits.
Pachyderm now tracks subvenance, the inverse of provenance.
Branches now track provenance and subvenance.
Restrictions on delete-commit have been removed, you can now delete any input commit and the DAG will repair itself appropriately.
Pachyderm workers no longer use long running grpc requests to schedule work, they use an etcd based queue instead. This solves a number of bugs we had with larger jobs.
You can now backup and restore your cluster with extract and restore.
Pipelines now support timeouts, both for the job as a whole or for individual datums.

Pachctl now has bash completion, including for values stored within it. (pachctl completion to install it)
pachctl deploy now has a --namespace flag to deploy to a specific namespace.
You can no longer commit directly to output repos, this would cause a number of problems with the internal model that were tough to recover from.

We've introduce a new type of input, Cron, which can be used to trigger pipelines based on time. #2150.

1.5.1 / 1.5.2

Bug Fixes

A pipeline can get stuck after repeated worker failures. (#2064)
pachctl port-forward can leave a orphaned process after it exits. (#2098)
alpine-based pipelines fail to load input data. (#2118)

Pipelines now support the “stats” feature. See the docs for details. (#1998)
Pipeline cache size is now configurable. See the docs for details. (#2033)
pachctl update-pipeline now only process new input data with the new code; the old input data is not re-processed. If it’s desired that all data are re-processed, use the --reprocess flag. See the docs for details. (#2034)
Pipeline workers now support “pipelining”, meaning that they start downloading the next datums while processing the current datum, thereby improving overall throughput. (#2057)

Bug fixes

Copy elision does not work for directories. (#1803)
Deleting a file in a closed commit fails silently. (#1804)
Pachyderm has trouble processing large files. (#1819)
etcd uses an unexpectedly large amount of space. (#1824)
pachctl mount prints lots of benevolent FUSE errors. (#1840)

New features

1.4.6

Bug fixes

get-logs returns errors along the lines of Invalid character…. (#1741)
etcd is not properly namespaced. (#1751)
A job might get stuck if it uses cp -r with lazy files. (#1757)
Pachyderm can use a huge amount of memory, especially when it processes a large number of files. (#1762)

API calls can start returning context deadline exceeded when the cluster is under heavy load. (#1796)

New features / improvements

Union input: a pipeline can now take the union of inputs, in addition to the cross-product of them. Note that the old inputs field in the pipeline spec has been deprecated in favor of the new input field. See the pipeline spec for details. (#1665)
Copy elision: a pipeline that shuffles files can now be made more efficient by simply outputting symlinks to input files. See the docs on shuffling files for details. (#1791)
pachctl glob-file: ever wonder if your glob pattern actually works? Wonder no more. You can now use pachctl glob-file to see the files that match a given glob pattern. (#1795)
Workers no longer send/receive data through pachd. As a result, pachd is a lot more responsive and stable even when there are many ongoing jobs. (#1742)

1.4.5

Bug fixes

Fix a bug where pachd may crash after creating/updating a pipeline that has many input commits. (#1678)
Rules for determining when input data is re-processed are made more intuitive. Before, if you update a pipeline without updating the transform, the input data is not re-processed. Now, different pipelines or different versions of pipelines always re-process data, even if they have the same transform. (#1685)
Fix several issues with jobs getting stuck. (#1717)
Fix several issues with lazy pipelines getting stuck. (#1721)
Fix an issue with Minio deployment that results in job crash loop. (#1723)
Fix an issue where a job can crash if it outputs a large number of files. (#1724)
Fix an issue that causes intermittent gRPC errors. (#1727)

New features

Pachyderm now ships with a web UI! To deploy a new Pachyderm cluster with the UI, use pachctl deploy <arguments> --dashboard. To deploy the UI onto an existing cluster, use pachctl deploy <arguments> --dashboard-only. To access the UI, simply pachctl port-forward, then go to localhost:38080. Note that the web UI is currently in alpha; expect bugs and significant changes.
You can now specify the amount of resources (i.e. CPU & memory) used by Pachyderm and etcd. See pachctl deploy --help for details. (#1676)
You can now specify the amount of resources (i.e. CPU & memory) used by your pipelines. See the pipeline spec for details. (#1683)

1.4.4

Bug fixes

A job can fail to restart when encountering an internal error.
A deployment with multiple pachd nodes can get stalled jobs.

update-pipeline can fail if the original pipeline has not outputted any commits.
pachd can crash if etcd is flaky.
pachd memory can be easily exhausted on GCE deployments.
If a pipeline is created with multiple input commits already present, all jobs spawn and run in parallel. After the fix, jobs always run serially.

Features

The processing of a datum can be restarted manually via restart-datum.
Workers' statuses are now exposed through inspect-job.

Bug fixes

Getting files from GCE results in errors.
A pipeline that has multiple inputs might place data into the wrong /pfs directories.
pachctl put-file --split errors when splitting to a large number of files.
Pipeline names do not allow underscores.

Azure backend returns an error if it writes to an object that already exists.

New features

pachctl get-file now supports the --recursive flag, which can be used to download directories.
pachctl get-logs now outputs unstructured logs by default. To see structured/annotated logs, use the --raw flag.

1.4.0

Features/improvements:

Correct processing of modifications and deletions. In prior versions, Pachyderm pipelines can only process data additions; data that are removed or modified are effectively ignored. In 1.4, when certain input data are removed (or modified), downstream pipelines know to remove (or modify) the output that were produced as a result of processing the said input data.

As a consequence of this change, a user can now fix a pipeline that has processed erroneous data by simply making a new commit that fixes the said erroneous data, as opposed to having to create a new pipeline.

Vastly improved performance for metadata operations (e.g. list-file, inspect-file). In prior versions, metadata operations on commits that are N levels deep are O(N) in runtime. In 1.4, metadata operations are always O(1), regardless of the depth of the commit.
A new way to specify how input data is partitioned. Instead of using two flags partition and incrementality, we now use a single glob pattern. See the glob doc for details.
Flexible branch management. In prior versions, branches are fixed, in that a commit always stays on the same branch, and a branch always refers to the same series of commits. In 1.4, branches are modeled similar to Git's tags; they can be created, deleted, and renamed independently of commits.
Simplified commit states. In prior versions, commits can be in many states including started, finished, cancelled, and archived. In particular, cancelled and archived have confusing semantics that routinely trip up users. In 1.4, cancelled and archived have been removed.
Flexible pipeline updates. In prior versions, pipeline updates are all-or-nothing. That is, an updated pipeline either processes all commits from scratch, or it processes only new commits. In 1.4, it's possible to have the updated pipeline start processing from any given commit.
Reduced cluster resource consumption. In prior versions, each Pachyderm job spawns up a Kubernetes job which in turn spawns up N pods, where N is the user-specified parallelism. In 1.4, all jobs from a pipeline share N pods. As a result, a cluster running 1.4 will likely spawn up way fewer pods and use fewer resources in total.
Simplified deployment dependencies. In prior versions, Pachyderm depends on RethinkDB and etcd to function. In 1.4, Pachyderm no longer depends on RethinkDB.
Dynamic volume provisioning. GCE and AWS users (Azure support is coming soon) no longer have to manually provision persistent volumes for deploying Pachyderm. pachctl deploy is now able to dynamically provision persistent volumes. See the deployment doc for details.

Removed features:

A handful of APIs have been removed because they no longer make sense in 1.4. They include:

ForkCommit (no longer necessary given the new branch APIs)
ArchiveCommit (the archived commit state has been removed)
ArchiveAll (same as above)
DeleteCommit (the original implementation of DeleteCommit is very limiting: only open head commits may be removed. An improved version of DeleteCommit is coming soon)
SquashCommit (was only necessary due to the way PPS worked in prior versions)
ReplayCommit (same as above)

1.3.0

Features:

Embedded Applications - Our “service” enhancement allows you to embed applications, like Jupyter, dashboards, etc., within Pachyderm, access versioned data from within the applications, and expose the applications externally.
Pre-Fetched Input Data - End-to-end performance of typical Pachyderm pipelines will see a many-fold speed up thanks to a prefetch of input data.
Put Files via Object Store URLs - You can now use “put-file” with s3://, gcs://, and as:// URLS.
Update your Pipeline code easily - You can now call “create-pipeline” or “update-pipeline” with the “--push-images” flag to re-run your pipeline on the same data with new images.
Support for all Docker images - It is no longer necessary to include anything Pachyderm specific in your custom Docker images, so use any Docker image you like (with a couple very small caveats discussed below).
Cloud Deployment with a single command for Amazon / Google / Microsoft / a local cluster - via pachctl deploy ...
Migration support for all Pachyderm data from version 1.2.2 through latest 1.3.0

Bug fixes:

False positive on running pipelines
Makefile bulletproofing to make sure things are installed when they're needed
Races within the FUSE driver
In 1.0 it was possible to get duplicate job ids which, that should be fixed now

Map jobs no longer return when sharded unless the files are actually empty
The fuse driver could encounter a bounds error during execution, no longer
Pipelines no longer get stuck in restarting state when the cluster is restarted
Failed jobs were being marked failed too early resulting in a race condition
Jobs could get stuck in running when they had failed
Pachd could panic due to membership changes
Starting a commit with a nonexistent parent now errors instead of silently failing
Previously pachd nodes would crash when deleting a watched repo
Jobs now get recreated if you delete and recreate a pipeline
Getting files from non existent commits gives a nicer error message
RunPipeline would fail to create a new job if the pipeline had already run
FUSE no longer chokes if a commit is closed after the mount happened
GCE/AWS backends have been made a lot more reliable

Tests:

From 1.0.0 to 1.1.0 we've gone from 70 tests to 120, a 71% increase.

1.0.0 (5/4/2016)

1.0.0 is the first generally available release of Pachyderm. It's a complete rewrite of the 0.* series of releases, sharing no code with them. The following major architectural changes have happened since 0.*:

All network communication and serialization is done using protocol buffers and GRPC.
BTRFS has been removed, instead build on object storage, s3 and GCS are currently supported.
Everything in Pachyderm is now scheduled on Kubernetes, this includes Pachyderm services and user jobs.
We now have several access methods, you can use pachctl from the command line, our go client within your own code and the FUSE filesystem layer
