Bumps github.com/mediocregopher/radix/v4 from 4.0.0-beta.1 to 4.0.0.

Changelog

Sourced from github.com/mediocregopher/radix/v4's changelog.

v4.0.0

Below is documented all breaking changes between v3 and v4. There are further enhancements which don't qualify as breaking changes which may not be documented here.

Major Changes

• Stop using ...opts pattern for optional parameters across all types, and switch instead to a (Config{}).New kind of pattern.

• Add MultiClient interface which is implemented by Sentinel and Cluster, Client has been modified to be implemented only by clients which point at a single redis instance (Conn and Pool). Methods on all affected client types have been modified to fit these new interfaces.

  • Cluster.NewScanner has been replaced by ScannerConfig.NewMulti.

• Conn has been completely re-designed. It is now always thread-safe. When multiple Actions are performed against a single Conn concurrently the Conn will automatically pipeline the Action's read/writes, as appropriate.

  • Pipeline has been re-designed as a result as well.

  • CmdAction has been removed.

• Pool has been completely rewritten to better take advantage of connection sharing (previously called "implicit pipelining" in v3) and the new Conn design.

  • EvalScript and Pipeline now support connection sharing.

  • Since most Actions can be shared on the same Conn the Pool no longer runs the risk of being depleted during too many concurrent Actions, and so no longer needs to dynamically create/destroy Conns.

  • A Pool size of 0 is no longer supported.

• Brand new resp/resp3 package which implements the [RESP3][resp3] protocol. The new package features more consistent type mappings between go and redis and support for streaming types.

• Usage of context.Context in many places.

  • Add context.Context parameter to Client.Do, PubSub methods, Scanner.Next, and WithConn.

  • Add context.Context parameter to all Client and Conn creation functions.

  • Add context.Context parameter to Action.Perform (previously called
