what GDBM is for other languages: a fast, simple persistence engine.

such as HTree and B+Tree, to support persistence of large object collections.

pglogical is a logical replication system implemented entirely as a
PostgreSQL extension. Fully integrated, it requires no triggers or
external programs. This alternative to physical replication is a
highly efficient method of replicating data using a publish/subscribe
model for selective replication.
The replication and load balancing plugin is a plugin for the mysqlnd library.
It can be used with PHP MySQL extensions (ext/mysql, ext/mysqli, PDO_MySQL) if
they are compiled to use mysqlnd. The plugin inspects queries to do read-write
splitting. Read-only queries are send to configured MySQL replication slave
servers all other queries are redirected to the MySQL replication master server.
Very little, if any, application changes required, dependent on the usage
scenario required.
