------------------------------------
Summary: Configure RAM buffer size used by IndexWriter with
oak-run indexing
Key: OAK-6718
URL: https://issues.apache.org/jira/browse/OAK-6718
Project: Jackrabbit Oak
Issue Type: Improvement
Components: lucene
Reporter: Chetan Mehrotra
Assignee: Chetan Mehrotra
Fix For: 1.8
Lucene IndexWriter uses 16M buffer by default. For reindexing of large repo via
oak-run it should be possible to set this to higher value like 300MB.
In one of the test which indexes 65M entries setting the buffer size to 300M
reduced the reindexing time from 2 hrs to 1.1 hrs
