DATABASE MANAGEMENT

摘要

Some examples relate to database management. In an example, data stored in a database may be sharded into a plurality of shards, wherein the database is coupled to a file system. Upon receiving data update for the database, data update may be applied only to a database file that stores data affected by the update, to generate an updated database file. A parameter related to a shard that includes the updated database file may be determined. If the parameter related to the shard exceeds a pre-defined threshold, updated database files may be identified in the shard, and data stored in the updated databases files may be merged into a single database file in the shard.
