I didn't realise you could even disable tlog when running SolrCloud, but as Anshum says it's a bad idea. In all possibility, even if it worked, removing transaction logs is likely to make your restart slower, SolrCloud would always be forced to do a full recovery because it cannot now use tlogs to do recovery which it tries to to speed things up.
Your problem is probably elsewhere. How many replicas do you have? Do you see this problem always or when you bounce the leaders? SOLR-6261 recently speeded that up and is scheduled to roll out with the next release but you can try out the patch meanwhile. Hello I am using solr 4.6.1 with over 1000 collections and 8 nodes. Restarting of nodes takes a long time (especially if we have indexing running against it) . I want to see if disabling transaction logs can help with a better robust restart. However I can't see any docs around disabling txn logs in solrcloud Can anyone help with info on how to disable transaction logs ? Thanks Nitin
