v1.14.0

What's Changed

This release adds LOAD_BALANCING_POLICY_SLOW_AVOIDANCE functionality, which makes the driver avoid the slowest node improving the latency. It is based on functionality already present in java-driver. Additionally couple of bug fixes were added.

• Do not try to query peers_v2 table upon connection against a ScyllaDB cluster by @mykaul in #171
• Send heartbeat OPTIONS message less frequent and enable keep alive by @sylwiaszunejko in #169

Full Changelog: v1.13.0...v1.14.0

v1.13.0

What's Changed

This release brings support for tablets to ScyllaDB's fork of gocql driver. Tablet support is an upcoming feature in ScyllaDB that changes the replication algorithm used in ScyllaDB. Drivers without support for tablets (for example old gocql versions) will continue to work, but the token awareness will not work properly in them, negatively affecting performance. gocql v1.13.0 is tablet-aware, meaning the driver will correctly route requests in tablet-enabled keyspaces.

• Introduce support for tablets by @sylwiaszunejko in #137
• Update CI to use new way of initializing keyspace with tablets by @sylwiaszunejko in #156
• Fix checking if tablets should be used in scyllaConnPicker Pick by @sylwiaszunejko in #158

Full Changelog: v1.12.0...v1.13.0

v1.12.0

What's Changed

• Merge upstream changes (gocql v1.6.0) by @sylwiaszunejko in #148
• Mark node as down if unable to dial control conn by @sylwiaszunejko in #150
• Fix aggregate bug by @sylwiaszunejko in #152

Full Changelog: v1.11.1...v1.12.0

v1.11.1

What's Changed

This release contains a number of changes merged from the upstream gocql repository:

• Re-resolve DNS hostnames as a fallback when all hosts are unreachable by @wprzytula in apache#1708
  This change should make the driver more resiliant to a situation when some nodes are replaced and their DNS names change.
• Add shard information to tracing by @sylwiaszunejko in apache#1716
• Use keyspace/table information from PREPARED response by @sylwiaszunejko in apache#1714
  An example where this helps: previously the token awareness feature would work properly only if the user set a correct keyspace name on a session. Now, the metadata received from Scylla is used instead. Also see: apache#1621

v1.11.0

What's Changed

This release is a essentially a rerelease of v1.8.0. This is due to the fact that this repository incorrectly had v1.8.0, v1.8.1, v1.9.0, v1.10.0 tags fetched from an upstream repository (see #139 and #110 for more context). Those versions have been retracted. v1.11.0 should be higher than any tag ever present in this repository.

Small changes for better CI stability:

• fix(docker-compose.yaml): increase memory limit to avoid hitting #126 by @dkropachev in #128
• Add healthchecks, switch from Docker Compose V1 to V2 by @sylwiaszunejko in #133

New Contributors

• @dkropachev made their first contribution in #128
• @sylwiaszunejko made their first contribution in #133

Full Changelog: v1.8.0...v1.11.0

v1.7.3

What's Changed

• Use ConnectionConfig values when establishing session to initial contact point by @zimnx in #106
• Run go vet and tests in all subpackages in CI by @zimnx in #107
