Many applications need full text search capabilities, this project provides a MapR-DB CDC Consumer that captures data changed and sends data to Elasticsearch for indexing. It also provides a Java library that based on OJAI to query transparently Elasticsearch.

The Search Client Examples directory contains sample code showing how to use the MapR-DB JSON Full Text Search plugin.

Note: it is possible to take a similar approach to add search capabilities to MapR-DB Binary tables.


MapR-DB JSON Geospatial Queries

This project is a Java library, based on S2 Geometry API, that provides Geospatial inclusion and proxmity query operators. The S2 library represents geospatial location as "cell", and are represented using a "cell id". This Java API, based on OJAI, allows developer to query cell id stored in a MapR-DB JSON attribute. This attribute can be indexed.

The Geospatial Client Examples directory contains sample code showing how to use the MapR-DB JSON Geospatial library.

Note: it is possible to take a similar approach to add search capabilities to MapR-DB Binary tables. (without the indexing of the cell id.)
