Elastic is already a mature product, with little to improve. Even 8.0 release is focused on speed and footprint. Many companies still use 2.x happily. License implications are not worth it.

Having interacted with Elasticsearch a lot, I assure you there is a lot for them yet to improve. Frankly, I think Elasticsearch followed the MongoDB model of "make it easy for developers to adopt and then make it good." MDB did that by making it easy to throw "schema-less" documents into their database and then later working on "advanced" things like avoiding data loss [0]. Elasticsearch did something similar in that you don't have to run a separate cluster coordination server like Zookeeper which Solr requires. It's also easy to get up and running with indexing unstructured data. Running it at scale with heavy workloads? There are still plenty of rough edges there. It's a good way to gain market share and both products have definitely improved, but I wouldn't want my day job to involve the operation of a large Elasticsearch cluster.

  Indeed, there is a lot of room to improve. I managed a cluster that grew from 9 to 40 then to 60 EC2 Servers over 2 years, with all updates and support we could afford. It was a a nightmare to manage. The amount of cluster rebalancing, magic nodes that claim to be leader and then do not behave like it is amazing. I don't want ever to get back managing it again. Last thing I did (ES7 at the time) was to split the cluster in many smaller clusters, reimplement all counters on relational databases and use as little of ES as possible. As a former colleague used to say: Elasticsearch is MongoDB for people ashamed of using MongoDB. Hope AWS and Elastic tension helps them to do a better job there.

    Curious, I never came across someone using ES as a replacement for Mongo.
