Hi all, I have a SolrCloud cluster with a collection (2.5M docs) with 3 shards and 15 replicas. There is a solrj application that feeds the collection, updating few documents every hour, I don't understand why, at end of process, the hard commit takes about 8/10 minutes.
Even if there are only few hundreds of documents. This is the autocommit configuration: <autoCommit> <maxDocs>10000</maxDocs> <maxTime>1000</maxTime> <openSearcher>false</openSearcher> </autoCommit> In your experience why hard commit takes so long even for so few documents? Now I'm changing the code to softcommit, calling commit (waitFlush = false, waitSearcher = false, softCommit = true); solrServer.commit(false, false, true);. I have configured NRTCachingDirectoryFactory, but I'm a little bit worried if a server goes down (something like: kill -9, SolrCloud crashes, out of memory, etc.), and if, using this strategy softcommit+NRTCachingDirectory, SolrCloud instance could not recover a replica. Should I worry about this new configuration? I was thinking to take a snapshot of everything every day, in order to recover immediately the index. Could this be considered a best practice? Thanks in advance for your time, Vincenzo -- Vincenzo D'Amore email: v.dam...@gmail.com skype: free.dev mobile: +39 349 8513251
