JDBC optimizations: setReadOnly, setMaxRows -------------------------------------------
Key: SOLR-812 URL: https://issues.apache.org/jira/browse/SOLR-812 Project: Solr Issue Type: Improvement Components: contrib - DataImportHandler Affects Versions: 1.3 Reporter: David Smiley I'm looking at the DataImport code as of Solr v1.3 and using it with Postgres and very large data sets and there some improvement suggestions I have. 1. call setReadOnly(true) on the connection. DIH doesn't change the data so this is obvious. 2. call setAutoCommit(false) on the connection. (this is needed by Postgres to ensure that the fetchSize hint actually works) 3. call setMaxRows(X) on the statement which is to be used when the dataimport.jsp debugger is only grabbing X rows. fetchSize is just a hint and alone it isn't sufficient. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
