Cassandra database client in Dart #

  • The package can be used with Cassandra (and Elassandra).
  • It is able to handle basic types (but: no map yet).
  • Detects and auto-connects peers.
  • Auto-selects peers with lower latencies.
  • Select the peer that is most likely to contain the data (use: hint).

This is an experimental library and protocol, use at your own risk.

How to contribute #

Check and follow the spec of the wire protocol v4 before creating a PR.

0.3.0 #

  • Peer-selection hint handles List<String> primary keys.
  • Warnings in query responses are now handled and included in ResultPage.

BREAKING CHANGES:

  • TIMESTAMP is now serialized from/to DateTime (with UTC).
  • Refactored methods around frame parsing (internals).
  • Client also has the hint parameter (as Cluster has it).

Better cluster handling:

  • Automatically connect to new peers.
  • Peer selection based on low latency connection.
  • Peer selection based on hint to connect to primary node directly (limited to String ids).

  • Updated to use Uint8List.

0.1.1 #

  • Added types: timestamp, timeuuid and counter.
  • Fixed a bug where it would crash on selecting and inserting a null field.
  • Updated to Dart 2.3 standards

    • PageRows implements Page<Row> from package:page.
