ZEO - Single-server client-server database server for ZODB

ZEO is a client-server storage for ZODB for sharing a single storage among many clients. When you use ZEO, a lower-level storage, typically a file storage, is opened in the ZEO server process. Client programs connect to this process using a ZEO ClientStorage. ZEO provides a consistent view of the database to all clients. The ZEO client and server communicate using a custom protocol layered on top of TCP.

Some alternatives to ZEO:

• NEO is a distributed-server client-server storage.
• RelStorage leverages the RDBMS servers to provide a client-server storage.
