Hi all! Please advice. I'm using RMQ river to post data. When a queue has near 45K messages and I create river, after maybe 20-25 seconds on 4GB of heap size I take java heap space error. I was tried to use threadpool "index" and "bulk" parameters in my cluster, but no positive results. Also tried to set up a different parameters on merge and store - the same. I reviewed a same questions at mail-lists, and src of river and seems the problem that river sends too much bulk requests. I didn't tried, but at src of a couchdb river there is a blocking queue, which seems blocks too much bulk requests. My question is: Has anybody configure RMQ river properly with ES, or maybe I'm wrong somewhere? Thanks. ---

Hi Dennis, I am using rabbitmq-river and have been testing it under heavy load last week. In some situations I observed the same error. After some investigations I discovered that source of my problems is that I have defined very agressive analyzer. Changing it to more relaxed fixed this problem. I still have some issues with stability of this plugin. On server side my configuration is: threadpool.bulk.type: fixed threadpool.bulk.size: 60 threadpool.bulk.queue\_size: 300 Best regards, Nickolay Kolev 14 октомври 2013, понеделник, 15:58:04 UTC+3, dennis yermakov написа: > Hi all! > Please advice.
