SQL Access to Elasticsearch
Elasticsearch is a distributed, RESTful search and analytics engine capable of solving a growing number of use cases. It centrally stores your data so you can discover the expected and uncover the unexpected.
As Elasticsearch offers some limited driver interfaces we are often asked how our Elasticsearch Drivers compare. In addition to supporting Elasticsearch across all of our supported Driver and Adapter Technologies, our Drivers also provide true SQL-92 interfaces.
Key Differentiators
CData Drivers offer all of the functionality of the native drivers and more, including the following:
- Enables SQL access to Elasticsearch v2.2 and above (compared to v6.3 and above)
- Compatible with all Elasticsearch subscriptions, from Basic/Open Source to Platinum
- Connects to the SQL endpoint and REST endpoint (as opposed to only the SQL endpoint)
- Supports
INSERT, UPDATE, and DELETE - not just SELECT
- Returns the
_score column without explicitly requiring the SCORE() function
- Allows filtering on text fields using
= and LIKE (as opposed to only LIKE)
- Built-in logic to choose a search type (Query String, Match Phrase, Wildcard) based on whether a text field is analyzed or non-analyzed
- Supports working with arrays
- Supports working with nested types
- Enables JOIN queries across indexes as well as JOIN Types on the server
