Noble Paul updated SOLR-1293: ----------------------------- Attachment: SOLR-1293.patch The patch is untested. The internal patch we used was on an older svn version . That patch is just merged to trunk and I am submitting that. I plan to test this sometime soon. But for those need this really badly this can be a starting point. refer the wiki page for usage details http://wiki.apache.org/solr/LotsOfCores > Support for large no:of cores and faster loading/unloading of cores > ------------------------------------------------------------------- > > Key: SOLR-1293 > URL: https://issues.apache.org/jira/browse/SOLR-1293 > Project: Solr > Issue Type: New Feature > Reporter: Noble Paul > Fix For: 1.5 > > Attachments: SOLR-1293.patch > > > Solr , currently ,is not very suitable for a large no:of homogeneous cores > where you require fast/frequent loading/unloading of cores . usually a core > is required to be loaded just to fire a search query or to just index one > document > The requirements of such a system are. > * Very efficient loading of cores . Solr cannot afford to read and parse and > create Schema, SolrConfig Objects for each core each time the core has to be > loaded ( SOLR-919 , SOLR-920) > * START STOP core . Currently it is only possible to unload a core (SOLR-880) > * Automatic loading of cores . If a core is present and it is not loaded and > a request comes for that load it automatically before serving up a request > * As there are a large no:of cores , all the cores cannot be kept loaded > always. There has to be an upper limit beyond which we need to unload a few > cores (probably the least recently used ones) > * Automatic allotment of dataDir for cores. If the no:of cores is too high al > the cores' dataDirs cannot live in the same dir. There is an upper limit on > the no:of dirs you can create in a unix dir w/o affecting performance -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
