Subject [jira] [Commented] (SOLR-3980) Incorporate lazily-loaded cores into core listings for clients
Date Tue, 30 Oct 2012 00:04:11 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3980?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13486533#comment-13486533

Erick Erickson commented on SOLR-3980:
--------------------------------------

In looking at this a bit more, the only way that currently exists to get a list of cores is
to do a core admin STATUS command. Unfortunately, that loads all the cores and in the case
where there are a large number of them, this will be unacceptable.

I propose a new core admin command LIST that will return a simple listing of the cores, just
the name. The Admin UI will need to use this to display the actual list, then make a STATUS
request when the user is drilling down....

I suppose another solution would be an extra parameter for STATUS, namesOnly=true or some
such, but I don't really like that, although I'd be willing to be persuaded otherwise.

> Part of SOLR-1293 (supporting lots of cores) will require we do something to allow clients
(particularly the admin GUI) to get a full list of all possible cores, whether they've been
loaded or not.
