Headquartered in San Jose, California, privately held MapR provides the MapR Converged Data Platform, which includes MapR-DB, MapR’s Hadoop distribution, MapR-FS and MapR Streams. MapR-DB is an operational multimodel DBMS compatible with Apache HBase. It is available on-premises and through various cloud providers. MapR-DB is a distributed DBMS specialized for modern data types, such as JSON. It can also support rich content types, such as audio, video and images. The DBMS supports ANSI-compatible SQL access via Apache Drill, which is included in the overall MapR Converged Data Platform.
However, the DBMS’ ACID capabilities are limited to a single row or entity within the DBMS. This limits its applicability to traditional transactional use cases, but it is suitable for lightweight events and observations. MapR-DB’s selective geographic replication features also make it a good fit for use cases with distributed variable data.
MapR-DB can be used for HTAP use cases using Apache Spark to provide in-transaction analytics.
