Upgrading from 9.x

This update contains some significant performance improvements in the form of reduced Tokio scheduling overhead and reduced memory usage during the frame encoding process. It also contains several cosmetic changes designed to support future scenarios where Valkey and Redis start to diverge from one another.

Notable Breaking Changes

The compiler should guide callers through most of these changes.

• The auto_pipeline config option was removed. All clients now automatically pipeline commands across Tokio tasks.
• The BackpressureConfig struct was removed. Callers should use max_command_buffer_len instead.
• The HEXPIRE, HTTL, etc, commands are now gated by an i-hexpire feature flag. Note that this requires Redis > =7.2.5.
• Some potentially redundant ReplicaConfig fields were removed. The client now uses the associated ReconnectPolicy fields instead, where applicable.
• The types module was becoming too large and needed refactoring. Many types were moved to submodules, which likely requires changes to certain import statements.
• Many of the common public types were renamed to remove the Redis prefix, such as RedisConfig, RedisClient, RedisPool, etc.
• rustls-native-certs was upgraded to 8.x.
• The specialize-into-bytes feature flag was removed. This is now the default behavior.
• The on_error and error_rx event handler interface now contains an optional server identifier.

Behavior Changes

• In the past fred spawned a separate task per connection in order to read from all sockets concurrently. In 10.0.0 each client reads and writes to all connections in a single task.
• Write throughput is improved by a factor of 3-5x depending on the use case.
• All transactions are now pipelined automatically.

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

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.
