About shardingsphere
Apache ShardingSphere is an Apache 2.0 licensed, Java based distributed database ecosystem positioned as Database Plus — a standards and enhancement layer that sits above heterogeneous databases so applications can connect to, govern, and compute across them as if they were one database, aimed at enterprise data architects and developers running sharded, multi database estates.
