2.0.0 ----- - Support multiple control connections with an upper limit and policy-controlled priority. - Cabal file improvements: bounds, version, etc. - Switch from unmaintained cryptonite to crypton - Add sufficient API tools for token-routing aware policy: - Accessors to lookup the replication for a keyspace, and to get the replicas for a given prepared query and its query values. - Pass prepared query and values to policy when selecting host - Track replication information for keyspaces and nodes - Better handling of prepared queries: Prevent re-prepare if the user has eagerly prepared a query. - Better code sharing between default policies. - Host events to pass Hosts, not addresses. This allows policies to better handle ups and downs, as well as re-numbering. It makes it easier to write a policy that prefers a given DC. - Track peers more carefully, and track them via UUID, not address. - Allow connection upgrading via min-max protocol version. Instead of setting a fixed protocol version, allow setting a min and max, and upgrade when possible. Breaking Changes: - Policy has a new `priority` function - Policy Events now have `Host`s instead of addresses, except for the new `AddrDown` for the case of a `HostDown` CQL event where the `Host` in question can't be found. - Policy `select` function accepts an additional argument with token-based routing information if it is available. - Settings has `_minProtoVer` and `_maxProtoVer` instead of `_protoVersion` - Settings has an additional field `_maxControlConnections` Porting Guide: If using one of the included policies, the only necessary change should be to set a minimum and maximum protocol versions instead of a single version. If not using an included policy, an existing policy can be ported by ignoring the additional argument to select, and by adjusting the event handler to handle `Host`s rather than addresses. Hosts have an address field, so porting should be straightforward. However, the changed policy API makes it possible to have a token aware routing policy. It's worth taking a look at that while porting. The improved `HostEvent` API should make it easier to handle host renumbering more gracefully as well. 1.1.1 ----- - Compatibility with `network >= 3`. 1.1.0 ----- - Improve configuration of retry settings and refactor exceptions (https://gitlab.com/twittner/cql-io/issues/13). - Document and export the 'getResult' function alongside the low-level query API. - Replace monad-control with unliftio. - Remove dependency on tinylog, introducing a minimal logging interface that can be hooked up to any logging library. Tinylog integration has moved to the new cql-io-tinylog library. 1.0.1.1 ------- - Add more documentation on queries. 1.0.1 ------ - Address an issue whereby Cassandra 'Error' responses might be mistakenly thrown by the (internal) withRetries function, possibly leading to problems with the automatic (re-)preparation of prepared queries upon 'Unprepared' server responses. 1.0.0 ------ - Add support for CQL V4 binary protocol. - Remove support for CQL V2 binary protocol. - Add support for SASL-based authentication handlers. - Bugfix: Retries for error responses were not handled correctly. - Update and extend test suite. - Require `cql >= 4.0` 0.16.0 ------ - Update Cabal settings to allow `cql` >= 3.1 0.15.2 ------ - Update `async` dependency 0.15.1 ------ - Use `retry >= 0.7` instead of internal module 0.15.0 ------ - Add experimental TLS support 0.14.5 ------ - Add `trans` to execute "lightweight transactions" 0.14.4 ------ - Update dependencies 0.14.3 ------ - Bugfixes 0.14.2 ------ - Export `PrepareStrategy` from `Database.CQL.IO` 0.14.1 ------ - Support for prepared queries - Bugfixes - `Control.Retry` module update to match version 0.6 0.13.2 ------ - Retry on `IOException` - Update dependencies 0.13.1 ------ - Support `monad-control` 1.* 0.13.0 ------ - Add `setMaxRecvBuffer` option 0.12.2 ------ - Update dependencies 0.12.1 ------ - Update dependencies 0.12.0 ------ - Remove wait-queue - Add more type-class instances 0.10.0 ------ - Add `MonadClient` type-class - Add retry settings 0.9.7 ----- - Bugfix release 0.9.6 ----- - Initial release
