v.1.1.54362New Feature
Added Consistent Hashing Functions for Reduced Network Traffic
Added consistent hashing functions:yandexConsistentHash,jumpConsistentHash,sumburConsistentHash. They can be used as a sharding key in order to reduce the amount of network traffic during subsequent reshardings.
Why it matters
These functions provide a way to implement sharding keys that minimize network traffic during resharding operations by consistently distributing data across shards. This reduces data movement and improves efficiency when cluster topology changes.How to use it
Use the functionsyandexConsistentHash, jumpConsistentHash, or sumburConsistentHash as the sharding key in your table definitions or queries to enable consistent hashing for data distribution. For example, specify the desired function in the sharding key expression to achieve more stable and efficient shard mapping.
