[Unreleased]

Added

Changed

Fixed

[1.3.1] - 2022-12-13

Fixed

  • Panic in RackAwareRoundRobinPolicy caused by wrong alignment on 32-bit platforms. (#1666)

[1.3.0] - 2022-11-29

Added

  • Added a RackAwareRoundRobinPolicy that attempts to keep client->server traffic in the same rack when possible.

Changed

  • Supported versions of Go that we test against are now Go 1.18 and Go 1.19.

[1.2.1] - 2022-09-02

Changed

  • GetCustomPayload now returns nil instead of panicking in case of query error. (#1385)

Fixed

  • Nil pointer dereference in events.go when handling node removal. (#1652)
  • Reading peers from DataStax Enterprise clusters. This was a regression in 1.2.0. (#1646)
  • Unmarshaling maps did not pre-allocate the map. (#1642)

[1.2.0] - 2022-07-07

This release improves support for connecting through proxies and some improvements when using Cassandra 4.0 or later.

Added

  • HostDialer interface now allows customizing connection including TLS setup per host. (#1629)

Changed

  • The driver now uses host_id instead of connect address to identify nodes. (#1632)
  • gocql reads system.peers_v2 instead of system.peers when connected to Cassandra 4.0 or later and populates HostInfo.Port using the native port. (#1635)

Fixed

  • Data race in HostInfo.HostnameAndPort(). (#1631)
  • Handling of nils when marshaling/unmarshaling lists and maps. (#1630)
  • Silent data corruption in case a map was serialized into UDT and some fields in the UDT were not present in the map. The driver now correctly writes nulls instead of shifting fields. (#1626, #1639)

[1.1.0] - 2022-04-29

Added

  • Changelog.
  • StreamObserver and StreamObserverContext interfaces to allow observing CQL streams.
  • ClusterConfig.WriteTimeout option now allows to specify a write-timeout different from read-timeout.
  • TypeInfo.NewWithError method.

Changed

  • Supported versions of Go that we test against are now Go 1.17 and Go 1.18.
  • The driver now returns an error if SetWriteDeadline fails. If you need to run gocql on a platform that does not support SetWriteDeadline, set WriteTimeout to zero to disable the timeout.
  • Creating streams on a connection that is closing now fails early.
  • HostFilter now also applies to control connections.
  • TokenAwareHostPolicy now panics immediately during initialization instead of at random point later if you reuse the TokenAwareHostPolicy between multiple sessions. Reusing TokenAwareHostPolicy between sessions was never supported.

Fixed

  • The driver no longer resets the network connection if a write fails with non-network-related error.
  • Blocked network write to a network could block other goroutines, this is now fixed.
  • Fixed panic in unmarshalUDT when trying to unmarshal a user-defined-type to a non-pointer Go type.
  • Fixed panic when trying to unmarshal unknown/custom CQL type.

Deprecated

  • TypeInfo.New, please use TypeInfo.NewWithError instead.

[1.0.0] - 2022-03-04
