hello shawn, thanks for the reply.
ok - i did some testing and yes you are correct. autocommit is doing the "commit" work in chunks. yes - the slaves are also going to having everything to nothing, then slowly building back up again, lagging behind the master. ... and yes - this is probably not what we need - as far as a replication strategy for the slaves. you said, you don't use autocommit. if so - then why don't you use / like autocommit? since we have not done this here - there is no established reference point, from an operations perspective. i am looking to formulate some sort of operation strategy, so ANY ideas or input is really welcome. it seems to me that we have to account for two operational strategies - the first operational mode is a "daily" append to the solr core after the database tables have been updated. this can probably be done with a simple delta import. i would think that autocommit could remain on for the master and replication could also be left on so the slaves picked up the changes ASAP. this seems like the mode that we would / should be in most of the time. the second operational mode would be a "build from scratch" mode, where changes in the schema necessitated a full re-index of the data. given that our site (powered by solr) must be up all of the time, and that our full index time on the master (for the moment) is hovering somewhere around 16 hours - it makes sense that some sort of parallel path - with a cut-over, must be used. in this situation is it possible to have the indexing process going on in the background - then have one commit at the end - then turn replication on for the slaves? are there disadvantages to this approach? also - i really like your suggestion of a "build core" and "live core". is this approach you use? thank you for all of the great input then -- View this message in context: http://lucene.472066.n3.nabble.com/should-slave-replication-be-turned-off-on-during-master-clean-and-re-index-tp3945531p3952904.html Sent from the Solr - User mailing list archive at Nabble.com.
