89014: jobs: Clear out claim info when pausing r=miretskiy a=miretskiy Clear out job claim information when job is paused. Clearing out claim information is beneficial since it allows operator to pause/resume job if they want to try to move job coordinator to another node. Addresses #82698 Release note: none 89026: kvserver: add `SmallEngineBlocks` testing knob and metamorphic params r=erikgrinaker a=erikgrinaker `@cockroachdb/repl-prs` to do the main review, tagging other teams for visibility/review of metamorphic test params. Resolves #86648. --- **kvserver: add `SmallEngineBlocks` testing knob** This patch adds a store testing knob `SmallEngineBlocks` which configures Pebble with a block size of 1 byte. This will store every key in a separate block, which can provoke bugs in time-bound iterators. Release note: None **sql/logictest: add metamorphic test param for small engine blocks** Uses a Pebble block size of 1 byte, to provoke bugs in time-bound iterators. Release note: None **kvserver/rangefeed: add metamorphic test param for small engine blocks** Uses a Pebble block size of 1 byte, to provoke bugs in time-bound iterators. Release note: None **kvserver/gc: add metamorphic test param for small engine blocks** Uses a Pebble block size of 1 byte, to provoke bugs in time-bound iterators. Release note: None **backupccl: add metamorphic test param for small engine blocks** Uses a Pebble block size of 1 byte, to provoke bugs in time-bound iterators. Release note: None 89030: codeowners: add test-eng to owners of pkg/workload r=srosenberg a=srosenberg Add test-eng as a code owner/watcher for pkg/workload. In light of recent and future improvements , , TestEng would prefer to be in sync with all changes to the workload code. Over time, the team plans to build expertise in this area.  https://github.com/cockroachdb/cockroach/pull/88362  https://github.com/cockroachdb/cockroach/issues/88566 Release note: None Release justification: test only change Co-authored-by: Yevgeniy Miretskiy <email@example.com> Co-authored-by: Erik Grinaker <firstname.lastname@example.org> Co-authored-by: Stan Rosenberg <email@example.com>

What is CockroachDB?
CockroachDB is a distributed SQL database built on a transactional and strongly-consistent key-value store. It scales horizontally; survives disk, machine, rack, and even datacenter failures with minimal latency disruption and no manual intervention; supports strongly-consistent ACID transactions; and provides a familiar SQL API for structuring, manipulating, and querying data.
For guidance on installation, development, deployment, and administration, see our User Documentation.
Starting with CockroachCloud
We can run CockroachDB for you, so you don't have to run your own cluster.
See our online documentation: Quickstart with CockroachCloud
Starting with CockroachDB
- Install CockroachDB: using a pre-built executable or build it from source.
- Start a local cluster and connect to it via the built-in SQL client.
- Learn more about CockroachDB SQL.
- Use a PostgreSQL-compatible driver or ORM to build an app with CockroachDB.
- Explore core features, such as data replication, automatic rebalancing, and fault tolerance and recovery.
CockroachDB supports the PostgreSQL wire protocol, so you can use any available PostgreSQL client drivers to connect from various languages.
- For recommended drivers that we've tested, see Install Client Drivers.
- For tutorials using these drivers, as well as supported ORMs, see Example Apps.
- CockroachCloud - Steps to create a free CockroachCloud cluster on your preferred Cloud platform.
- Manual - Steps to deploy a CockroachDB cluster manually on multiple machines.
- Cloud - Guides for deploying CockroachDB on various cloud platforms.
- Orchestration - Guides for running CockroachDB with popular open-source orchestration systems.
- CockroachDB Community Slack - Join our slack to connect with our engineers and other users running CockroachDB.
- CockroachDB Forum and Stack Overflow - Ask questions, find answers, and help other users.
- Troubleshooting documentation - Learn how to troubleshoot common errors, cluster setup, and SQL query behavior.
