Description

An MPP-based analytics DBMS embracing the MySQL protocol

Embeddable persistent key-value store optimized for fast storage (flash and RAM)

Industry standard data logging and graphing tool for time series data. RRD is an acronym for round-robin database.

The data is stored in a circular buffer, thus the system storage footprint remains constant over time.

OLTP DBMS based on a distributed architecture and highly compatible with MySQL and Oracle

Primary database model
