Milvus now stores element-nullable and nested arrays as native Arrow lists.
This update adds the ability for individual members of a set to expire automatically after a certain time, similar to how individual fields in a hash can expire. This allows sets to manage time-limited data like active sessions or temporary tags without needing extra structures or manual cleanup.
redis/redis · Feature · impact 9/10 · +7780 -1102Data structure expiration managementCode reuse through shared expiration mechanismsLazy expiration strategyIntegration with existing command APIsThis update introduces a new consumer group assignor called 'uniform2' that improves load balancing by evenly distributing partitions of each topic among subscribers, ensuring a fairer and more stable workload distribution compared to the previous uniform assignor. It maintains partition stickiness and minimizes partition movement while guaranteeing deterministic assignments.
