Subject [jira] [Updated] (SOLR-4030) Allow rate limiting Directory IO based on the IO context
Date Mon, 10 Dec 2012 02:29:23 GMT

     [ https://issues.apache.org/jira/browse/SOLR-4030?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mark Miller updated SOLR-4030:
------------------------------

    Attachment: SOLR-4030.patch

Here is a simple patch that lets you use a rate limited directory wrapper - you can set the
rate for each of the io contexts that lucene provides. If no limited are configured, no rate
limited directory wrapper is completed.
