Apache ShardingSphere document, v5.0.0-beta 1.2 Features 1.2.1 Data Sharding • Database sharding & Table sharding • Replica query • Sharding strategy customization • Centre‐less Distributed primary key exceeding affordable threshold. What’s more, database sharding can also effectively disperse TPS. Table sharding, though cannot ease the database pressure, can provide possibilities to transfer distributed
