Hey, there are several possibilties to increase performance. First you can have your own index for your percolation queries, so it scales independently from your data (there are use-cases where people do not have increasing data, but ever increasing amount of percolators). Second you can filter during percolation, so that a document is not executed against every registered query in case you already know, that some are not important.
See http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-percolate.html#_percolate_api However, if you only have 1 shard, you should be able to scale out anyway. Can you check your stats? Do you hit all those nodes evenly? Maybe you created some 'hot node'? --Alex On Mon, Jul 21, 2014 at 6:57 AM, Seungjin Lee <sweetest0...@gmail.com> wrote: > Hi all, > > for testing, I have one index with only 1 shard and 4 replicas. > > in .percolator type of that index, there are 1.5k queries to be percolated. > > and total 5 modern machines with 48G ram, assinged 12G for elasticsearch > on each node. > > What I'm seeing now is, it rarely scales out in performance perspective of > view. > > with only 1 node, percolate throughput is about 15k/s > > with 5 nodes, it's about 18k/s. > > > I thought that If I have 1 shard and make number of replica same as number > of machines we have, performance statistic will also linearly scales out as > number of node increases. > > any comment will be very helpful > > thanks > > -- > You received this message because you are subscribed to the Google Groups > "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to elasticsearch+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/elasticsearch/CAL3_U42E%3DoqH%2BXQ7svkf5FdEV2fM5DxZr5pGNFcwvTcw-h%2BzvQ%40mail.gmail.com > <https://groups.google.com/d/msgid/elasticsearch/CAL3_U42E%3DoqH%2BXQ7svkf5FdEV2fM5DxZr5pGNFcwvTcw-h%2BzvQ%40mail.gmail.com?utm_medium=email&utm_source=footer> > . > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
