Release Highlights

Upgrade action item summary

• Before upgrade
  • If you’re using ES v6: do not deploy this version until after moving to ES v7 or later
  • If you’re using ES v7+: upgrade schema to include new builtin search attributes (see Schedules section below)
  • If you used the experimental Schedules feature in 1.17: delete all schedules and recreate them after upgrading
• After upgrade
  • Change dynamic config matching.useOldRouting to false on all nodes as close in time as possible. This will cause temporary matching disruption during the propagation.
  • Remove publicClient from static config and restart all nodes (if you have problems with this change please let us know)
  • Consider enabling host-level worker pool and multi-cursor task processing (see Task processing section below)
  • Consider setting persistence rate limits (see Persistence rate limiting section below)

Elasticsearch v6 support is removed

Elasticsearch v7 became the default supported version in 1.12.0 release. In 1.18.0, Elasticsearch v6 support is completely removed. If you are still using Elasticsearch v6, don't upgrade to 1.18.0. Upgrade Elasticsearch first following the migration guide.

Along with v6 support removal, we added Elasticsearch v8 support. Elasticsearch v8 doesn’t have breaking changes that affect Temporal.

Batch API

This release introduces new batch operation APIs in the Frontend Service. The feature is enabled by default.

• StartBatchOperation: Start a batch operation.
• StopBatchOperation: Stop a running batch operation.
• DescribeBatchOperation: Get detail information about a batch operation.
• ListBatchOperations: List all the batch operations.

By default, the APIs support one concurrent operation per Namespace. This value is configurable by dynamic config: frontend.MaxConcurrentBatchOperationPerNamespace.

Use DescribeBatchOperation or metrics batcher_processor_requests and batcher_processor_errors to monitor the progress of batch operations.

Cluster API

The following Cluster APIs moved from the admin service to the operator service. Those APIs will be deprecated in the admin service in a future release.

• AddOrUpdateRemoteCluster: Add or update a connection configuration to a remote Cluster.
• RemoveRemoteCluster: Remove a connection to a remote Cluster.
• ListClusters: List the configuration of all connected Clusters.

Task processing

Host level task scheduler

• Host level task scheduler now uses separate task channels for each namespace for better resource isolation.
• Deprecated the dynamic config history.[timer|transfer|visibility]TaskHighPriorityRPS.

Multi-cursor queue

New multi-cursor queue implementation for better resource isolation and handling cases not covered by host-level task scheduler: too many pending tasks, stuck queue ack level, etc.

• The new implementation can be enabled by setting the value of dynamic config history.[timer|transfer|visibility]ProcessorEnableMultiCursor to true.
• The host-level worker pool for the corresponding queue should also be enabled, otherwise the above dynamic config won’t take effect. This can be done by setting history.[timer|transfer|visibility]ProcessorEnablePriorityTaskScheduler to true.

Task Loading

• The dynamic config history.[timer|transfer|visibility]ProcessorMaxPollHostRPS can be used to limit the throughput of the queue processor. This is very useful for recovering from a persistence outage which leads to a large task queue backlog in persistence. Set the value to a small number and gradually increase to ensure a smooth draining of the backlog. By default, value for this config is 0 and will fallback to 30% of the history.persistenceMaxQPS for transfer and timer queue and 15% for visibility queue.

Metrics

New task processing related metrics are added for better visibility.

• task_latency_load: measures the duration from task generation to task loading (task schedule to start latency for persistence queue).
• task_latency_schedule: measures the duration from task submission (to task scheduler) to processing (task schedule to start latency for in-memory queue).
• queue_latency_schedule: measures the time it takes to schedule 100 tasks in one task channel in the host level task scheduler. If there are less than 100 tasks in the task channel for 30s, the latency will be scaled to 100 tasks upon emission. NOTE: this is still an experimental metric and is subject to change.

Retry behavior

Consolidated retry logic for APIs calls to two places: service handler (by an interceptor) and service client for calling other temporal services or persistence. Limited retry maximum attempts and removed retry logic in other places to avoid potential retry storm.

Persistence rate limiting

Persistence layer rate limiter prioritizes user requests (e.g. start workflow, signal workflow, etc.) over system background requests (e.g. task loading, requests incurred by task processing, replication, etc.)

Persistence max QPS for each namespace can be set by tuning the dynamic config [frontend|history|matching|worker].persistenceNamespaceMaxQPS. By default, this value is 0 and will fallback to the overall host persistence QPS set by [frontend|history|matching|worker].persistenceMaxQPS.

Persistence metrics persistence_requests, persistence_latency and persistence_error* now also contains namespace tag for better observability.

UpsertMemo

This release adds UpsertMemo to modify existing workflow memo. It works similarly to UpsertSearchAttributes. However, on the visibility side, the memo is updated only when used with advanced visibility (i.e. Elasticsearch). When used with standard visibility (SQL databases), the memo is not being updated currently, and the workflow memo can be retrieved correctly only from the mutable state (that is, you can call DescribeWorkflowExecution to retrieve it).

Matching routing

Task queues are now distributed among matching nodes based on namespace and type, for better load balancing. This change is disabled by default to avoid disruption during the upgrade. After upgrading to 1.18, you should make a dynamic config change on all nodes simultaneously to set matching.useOldRouting to false. You can use the following snippet:

# Remove this after upgrading to 1.19:
matching.useOldRouting:
- value: false

This change will cause a short disruption to Task dispatch as nodes reload the dynamic config and then Task Queues get moved between matching nodes. You’ll also see some persistence errors in logs for a few minutes.

We plan to make this routing the default in 1.19, so if you don’t make the dynamic config change, it’ll happen during the next upgrade.

Schedules

A few incompatible changes were made to the Schedules feature, which was introduced as experimental in 1.17. If you have created any Schedules, you should delete them before upgrading to this release, and recreate them after the upgrade.

The Schedule feature is now enabled by default.

If you're using Advanced Visibility (i.e. Elasticsearch), Schedules don’t appear in Workflow lists anymore. If you’re not using Elasticsearch, Schedules continue to appear in Workflow lists for now.

There is one new builtin search attribute to support Schedule visibility. You can add it to Elasticsearch by running the upgrade script from the server repo. See the top of the script for environment variables to use to point it at your Elasticsearch. You can do this before or after the upgrade, but before creating any Schedules. (If you didn’t perform the v2 upgrade when upgrading to 1.17, which also added search attributes for Schedules, also do that now.)

schema/elasticsearch/visibility/versioned/v3/upgrade.sh

Frontend connections

The Temporal Server can now make internal frontend connections using the membership system for service resolution. This feature is optional in this release but will be the default in a future release. To switch to using membership service resolution:

• Remove the publicClient section from your config.
• If you were not using TLS to connect to frontend, no other changes are required.
• If you were using TLS and publicClient.hostPort was pointing directly to frontend(s), no other changes are required. It will still use TLS to connect to the frontend.
• If your publicClient.hostPort was pointing to a load balancer that terminated TLS, so the frontend itself did not terminate TLS, then you should also remove your global.tls.frontend.client and global.tls.systemWorker settings. Connections will be made directly from the worker role to the frontend role without TLS.

If you have problems with this change in your environment, please let us know.

Maximum retention

The maximum Namespace retention limit of 30 days is removed. Namespaces now can use any retention as needed, as long as the persistence has enough capacity for the storage.

Dynamic config interface

The dynamicconfig.Client interface was changed and simplified.

If you’re using Temporal with our pre-build container images or binaries, there’s nothing to do.

If you’re building your own Temporal binary and only refer to dynamicconfig.Client or dynamicconfig.NewFileBasedClient in your ServerOptions, you should be able to rebuild with no code changes.

If you’ve written a custom dynamic config implementation, you’ll need to change it to the new interface. This should be pretty straightforward, but if you have any questions, please contact us; we can help.
