Beside this, what is the purpose of elastic search?

ES is a document-oriented database designed to store, retrieve, and manage document-oriented or semi-structured data. When you use Elasticsearch, you store data in JSON document form. Then, you query them for retrieval.

One may also ask, is Elasticsearch expensive? Starting today, you can spin up a new deployment on the Elasticsearch Service for as low as $16.40 / month. This 60%+ cost reduction from the former starting price of $45 / month allows you to get started faster and makes it even easier to adopt the Elasticsearch Service as part of your environment.

Keeping this in view, is Elasticsearch a Datastore?

Elasticsearch as a primary database. Similar use case. Once the data is there is our databases (mostly SQL) we transform and store it on elasticsearch cluster for analysis and some adhoc projects but we do not use ES as primary. It's because, our systems were built long back and they are critical.

Where is curator Yml?

Why use Elasticsearch instead of SQL?

Elasticsearch is actually a JSON document store built upon the Apache Lucene search engine. There are other differences, of course: Lucene is better at managing large numbers of indexes, and can handle complex index searches much faster than a comparable SQL database can.

Where is Elasticsearch data stored?

If you're on Windows or if you've simply extracted ES from the ZIP/TGZ file, then you should have a data sub-folder in the extraction folder. According to the documentation the data is stored in a folder called "data" in the elastic search root directory.

Should Elasticsearch be used as a database?

Yes, you can use Elasticsearch as a data store but in reality is a Front End for Lucene, a search engine. It's an interface to make it easy and more simple to work with Lucene. The data and indexes stored by Lucene are optimized to work for full text searches, faceting, etc.

Can Elasticsearch be used as a cache?

using elasticsearch as a cache is fair. You can easily maintain it as cache layer on your primary storage. 1)But keep an eye on your reindexing strategy. When you will be adding 1 million documents to cluster every hour it will be very heavy operation on your hardware in terms of disk I/O.

Does Elasticsearch store data in memory?

1 Answer. Elasticsearch indexes are just files and they effectively cached in RAM by system. Usually if you have enough RAM Elasticsearch should work as fast as possible, especially for GET queries.
