I'm sending a REST call to optimize several indices together: 127.0.0.1:9200/index1,index2,index3/\_optimize?max\_num\_segments=1&force=true looking at the segments on disk, it is evident that the node optimizes one index at a time (finishes the rist, and then starts the next). More than that, it sometimes optimizes 1-3 indices and then stops. Is there a way to tell the node to optimize several indices concurrently? (the machine has 16 CPUs) Regards, Eran ## -- Please update your bookmarks!
