Time Contributors Over Time Apache ShardingSphere is positioned as a Database Plus, and aims at building a standard layer and ecosystem above heterogeneous databases. It focuses on how to reuse existing database ecosystem can be embedded flexibily. Developers can customize their ShardingSphere just like building with LEGO blocks. ShardingSphere became an Apache Top‐Level Project on April 16, 2020. Welcome supported are all weaved by plugins. Developers can customize their own Shard‐ ingSphere just like building lego blocks. There are lots of SPI extensions for Apache ShardingSphere now and increase continuously
