Subject [jira] [Commented] (SOLR-8349) Allow sharing of large in memory data structures across cores
Date Sun, 21 Feb 2016 23:38:18 GMT

    [ https://issues.apache.org/jira/browse/SOLR-8349?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15156295#comment-15156295

Noble Paul commented on SOLR-8349:
----------------------------------

bq.That may come in handy if/when a refresh mechanism is desired.

The refresh mechanism is built into the system . The name is a combination of name and version
example: {{myCsvFile/1}} (where '1' is the first version) Every component can be updated using
the API. If you add a new version of the blob, you should just simply  update your component
to use {{myCsvFile/2}}. The rest is automatically taken care of

> In some cases search components or analysis classes may utilize a large dictionary or
other in-memory structure. When multiple cores are loaded with identical configurations utilizing
this large in memory structure, each core holds it's own copy in memory. This has been noted
in the past and a specific case reported in SOLR-3443. This patch provides a generalized capability,
and if accepted, this capability will then be used to fix SOLR-3443.
