Aaron,Nodetool reports: 1.1.6-dse-p1What about inserted data using Hadoop? Will the secondary index execute concurrently or will this also be single threaded (on the same machine I mean)?
What version are you on ?but we are finding a secondary index is performing slowNot sure what you mean here.
Are secondary indexes concurrent or single threaded?Rebuilding a secondary index (via node tool) is a single threaded operation, but *all* indexes specified on the command line are built at the same time. Rebuilding any one index requires reading all the rows in the CF.Cheers
