# Concurrent Database Connections¶

DocTable makes it easy to establish concurrent database connections from different processes. DocTable objects can be copied as-is from one process to another, except that you must call .reopen_engine() to initialize in process thread. This removes now stale database connections (which are not meant to traverse processes) from the engine connection pool.

You may also want to use a large timeout using the timeout argument of the doctable constructor (provided in seconds).
