Upgrading from 7.x

Using ..Default::default() with the various configuration structs can avoid most of the breaking changes here.

  • ignore-auth-error
  • pool-prefer-active
  • reconnect-on-auth-error
  • auto-client-setname

• Changed several FromRedis type conversion rules. See below or the FromRedis docs for more information.
• Add a RedisJSON interface.
• Add a RESP2 and RESP3 codec interface.

Upgrading from 6.x

Notable interface changes:

• ArcStr has been replaced with bytes_utils::Str.
• Timeout arguments or fields now all use std::time::Duration.
• Many of the old global or performance config values can now be set on individual commands via the with_options interface.
• The RedisPool interface now directly implements ClientLike rather than relying on Deref shenanigans.
• The on_* event functions were moved and renamed. Reconnection events now include the associated Server.
• The tls_server_name field on Server is now properly gated by the TLS feature flags.
• Mocks are now optional even when the feature flag is enabled.

Notable implementation Changes:

• Pipeline and Transaction structs can now be reused. Calling exec, all, last, or try_all no longer drains the inner command buffer.
• Many of the default timeout values have been lowered significantly, often from 60 sec to 10 sec.
• In earlier versions the FromRedis trait implemented a few inconsistent or ambiguous type conversions policies.
  • Most of these were consolidated under the default-nil-types feature flag.
  • It is recommended that callers review the updated FromRedis docs or see the unit tests in responses.
