It can be seen that most data sources have been covered, especially relational databases providing a unified jdbc-river for data operations.

The source code of elasticsearch-river-jdbc is: github.com/jprante/elasticsearch-river-jdbc. this project provides detailed documents. The following uses SQL Server as an example to describe how to use it.

First, install elasticsearch-river-jdbc and run the following command in the elasticsearch directory:

./Bin/plugin -- install jdbc -- url Scheme

Then, install the JDBC library of SQLServer. The link is Microsoft JDBC Driver. Copy 'sqljdbc4. jar' to the lib folder in the installation directory of elasticsearch.

Considering the elasticsearch cluster, the preceding two steps must be performed on each node.

Last but not least, create a river in elasticsearch so that elasticsearch can automatically obtain data from SQLServer.
