Maximum pool size for ForkParser
--------------------------------
Key: TIKA-639
URL: https://issues.apache.org/jira/browse/TIKA-639
Project: Tika
Issue Type: Improvement
Components: parser
Reporter: Jukka Zitting
Assignee: Jukka Zitting
Fix For: 1.0
Currently the poolSize parameter in the ForkParser class just sets the number
of processes that are kept in the background even if no active parsing tasks
are in progress. New parsing request are always given a new process if there
are none left in the pool. In the worst case this can cause lots of processes
being forked during peak loads.
I'd like to change the poolSize parameter to specify the maximum number of
background processes that the ForkParser can
use at any given time. Unused processes would stay in the pool up to the
default five-second idle time after which they are reclaimed and the pool
shrunk until new requests come in again.
