As can be seen, most of the data sources have been covered, especially for relational databases that provide a unified jdbc-river for data operations.

ELASTICSEARCH-RIVER-JDBC's source code is: GITHUB.COM/JPRANTE/ELASTICSEARCH-RIVER-JDBC, the project provides detailed documentation, and the following is a simple example of how to use SQL Server.

First, you need to install ELASTICSEARCH-RIVER-JDBC and execute it in the Elasticsearch directory:

./bin/plugin--install JDBC--url

Then, install the JDBC Library for SQL Server, which is the link: Microsoft JDBC Driver. Copy the ' Sqljdbc4.jar ' to the Elasticsearch installation directory's Lib folder.

Given the Elasticsearch cluster, the above two steps need to be performed on each node.

The last and most critical step is to create a river in the Elasticsearch, allowing Elasticsearch to automatically fetch data from SQL Server.
