Changelog

Added the Redis cluster_max_redirections configuration option.
Timer spikes no longer occur when there is network instability with the central data store.
Fixed an issue where, if the window_size in the consumer group overriding config was different from the window_size in the default config, the rate limiting of that consumer group would fall back to local strategy.
Fixed an issue where the sync timer could stop working due to a race condition.

Refactored kong/tools/public/rate-limiting, adding the new interface new_instance to provide isolation between different plugins. The original interfaces remain unchanged for backward compatibility.

If you are using custom Rate Limiting plugins based on this library, update the initialization code to the new format. For example: 'local ratelimiting = require("kong.tools.public.rate-limiting").new_instance("custom-plugin-name")'. The old interface will be removed in the upcoming major release.
Fixed an issue where any plugins using the rate-limiting library, when used together, would interfere with each other and fail to synchronize counter data to the central data store.
Fixed an issue with sync_rate setting being used with the redis strategy. If the Redis connection is interrupted while sync_rate = 0, the plugin now accurately falls back to the local strategy.
Fixed an issue where, if sync_rate was changed from a value greater than 0 to 0, the namespace was cleared unexpectedly.
Fixed some timer-related issues where the counter syncing timer couldn’t be created or destroyed properly.
The plugin now creates counter syncing timers during plugin execution instead of plugin creation to reduce some meaningless error logs.
Fixed an issue where Kong Gateway produced a log of error log entries when multiple Rate Limiting Advanced plugins shared the same namespace.

Enhanced the resolution of the RLA sliding window weight.
The plugin now checks for query errors in the Redis pipeline.
The plugin now checks if sync_rate is nil or null when calling the configure() phase. If it is nil or null, the plugin skips the sync with the database or with Redis.

The redis strategy now catches strategy connection failures.
The /consumer_groups/:id/overrides endpoint has been deprecated. While this endpoint will still function, we strongly recommend transitioning to the new and improved method for managing consumer groups, as documented in the Enforcing rate limiting tiers with the Rate Limiting Advanced plugin guide. You can also find detailed information on creating consumer groups in the API Documentation.
Fixed an issue that impacted the accuracy with the redis policy. #10559

The shared Redis connector now supports username + password authentication for cluster connections, improving on the existing single-node connection support. This automatically applies to all plugins using the shared Redis configuration.

Added the ability to customize the error code and message with the configuration parameters error_code and error_message.

Kong Gateway now disallows enabling the plugin if the cluster strategy is set with DB-less or hybrid mode.

Added the redis.username and redis.sentinel_username configuration parameters.
The redis.username, redis.password, redis.sentinel_username, and redis.sentinel_password configuration fields are now marked as referenceable, which means they can be securely stored as secrets in a vault. References must follow a specific format.

Added the enforce_consumer_groups and consumer_groups configuration parameters.

Deprecated the timeout field and replaces it with three precise options: connect_timeout, read_timeout, and send_timeout.
Added redis.keepalive_pool, redis.keepalive_pool_size, and redis.keepalive_backlog configuration options.
ssl_verify and server_name configuration options now support Redis Sentinel-based connections.

Added the redis.ssl, redis.ssl_verify, and redis.server_name parameters for configuring TLS connections.
