100% Compatible with Greenplum DB

Deepgreen DB is derived from the open source Greenplum DB project. It maintains 100% compatibility with Greenplum DB. From SQL and stored procedures syntax, to storage formats on disk, to operation utilities such as gpstart or gpfdist, Deepgreen DB ensures full compatibility to minimize effort in redeployment. In particular:

• No need to reload data, except the case when quicklz is in use.
• No changes to SQL code (both DML and DDL).
• No changes to stored procedure code.
• No changes to user-defined function code.
• No changes to connectivity and authentication protocols such as odbc and jdbc.
• No changes to operational scripts such as bash backup scripts and cron jobs.

What is the difference, then?

In a word: Speed.

For most OLAP workload that is CPU-bound, Deepgreen DB runs up to 3X faster than Greenplum DB on average.
