Release v4.0.2-alpha

🚀 New Features:

• feat:After the Pika slave instance executes slaveof no one to remove the replication relationship with the master node, the slaveof information is persisted into the configuration file. #2973
• feat:Added support for backup and recovery in master-slave mode for Pika-Operator. #2968
• feat:Added the log-net-activities parameter in the configuration file to dynamically enable or disable the logging of certain connection-related activities. This can be adjusted with config get/set. #2964
• feat: Added the repl_connect_status metric to Pika info and integrated it into pika_exporter to facilitate monitoring of the replication status. #2961
• feat: Upgraded kubeblocks to version 0.9, improving and optimizing Pika-Operator to simplify code and support instance scale-down. #2860
• feat: Pika-Operator now supports starting in master-slave mode. See the README document for more details. [#2903]
• feat: Added keyspace_hits and keyspace_misses metrics to pika_exporter, enabling users to monitor key hit rates. #2579
• feat: RedisCache now avoids storing large keys to prevent excessive memory usage or the eviction of frequently accessed hot keys, which could impact performance. #2557

🐛 Fixes:

• fix:Fixed the rpoplpush command cache update issue, which caused inconsistency between the database and cache. #2976
• fix:Fixed compatibility issues between different versions of Pika-Exporter, which caused excessive logging and wasted disk resources. #2971

• fix: Fixed a cache inconsistency issue caused by the zpopmin command during deletion operations. #2892

🧹 Improvement:

• feat: Pika now supports dynamically modifying the max-subcompactions parameter to optimize the compact operation for L0 layers at runtime. #2965
• feat: Improved the log-retention-time parameter to dynamically adjust the number of days for log retention. #2963
• feat: Moved the Pika-Migrate code to the tools folder to simplify binary compilation in different environments for data migration. #2941
