Good warning. Yeah, beta software released to production.

There is that and also from fragility from ES. I was wondering what alternatives are out there to ES. I know of Solr only.

  Solr has the added complexity of zookeeper. ES isn't bad, but in an MT context you really have to layer a lot on top for security and configurability. It's possible it's not MT and they just didn't write the facade APIs. That'd be pretty crazy. My biggest complaint would be lack of plugin support.

    To be fair, ZK is great at it's job, and that responsibility is something ES has had a lot of trouble replicating.
  - StreamBright 9y ago
    If you want to have consistency in a distributed system you need something like ZK. If ES does not have ZK it surely has something else, probably with different trade offs.

  They have fixed most of the stability issues in 5.x. I suspect some of the problems people have had with AWS ES is actually using a pre-5.x version.

    Our 2.x cluster is much more stable than our 5.1.2 cluster despite the fact that our 5.x cluster is significantly smaller (in node count) than it's older brother. Also of note: Amazon's documentation on HTTP limits is wrong. There are some instance types listed as having a 100mb max payload that are only 10mb. We found that out when Logstash recorded a crapload of errors with the 10mb limit on what was allegedly a 100mb instance type.

    Well after talking to some of their tech guys we determined that we have different definitions for the work "fixed".

      Such as?
      - StreamBright 9y ago
        Such as disallowing configuration they do not like, having memory/resource leaks that they cannot find the root cause for and few other things I forgot already. G1GC is disallowed because they had a data corruption bug with it. This is few months back, they might changed some it already. The question for me is what do I get using ES over Solr? If Solr's features are enough for our use cases should I even try ES?

        Here is their resiliency status: https://www.elastic.co/guide/en/elasticsearch/resiliency/current/index.html https://www.elastic.co/guide/en/elasticsearch/resiliency/cur... It depends on your use case. If you are already familiar with Solr and it is good enough for your use case, then use it. Solr and ES are about the same feature-wise. Scaling is easier for ES because it is built-in. Here is a good comparison of their APIs. part 1: http://opensourceconnections.com/blog/2015/12/15/solr-vs-elasticsearch-relevance-part-one/ http://opensourceconnections.com/blog/2015/12/15/solr-vs-ela... part 2: http://opensourceconnections.com/blog/2016/01/22/solr-vs-elasticsearch-relevance-part-two/ http://opensourceconnections.com/blog/2016/01/22/solr-vs-ela...
