Subject [jira] [Commented] (CLEREZZA-564) CRIS: call optimize in an extra thread
Date Wed, 22 Jun 2011 12:32:47 GMT


Daniel Spicar commented on CLEREZZA-564:

Before we close this issue we I would like to know if a scheduling mechanism for optimizations
should be implemented. If so, it may be good to create a service in Clerezza that allows to
Schedule arbitrary jobs as I don't think it should be the responsibility of GraphIndexer or
exclusive to CRIS. 

Also, as mentioned on the mailing list we should further improve the optimization process
but because of concerns for stability I suggest to do this step by step after verifying that
 current changes have not affected stability negatively.

which optimizes the index, if there is not "much" activity (i.e.: analyze isLocked, InfoStream,
etc), every timeInterval seconds.
