Bedrock

Bedrock is a distributed relational DBMS designed for geo-replication. It uses SQLite as its backing data storage and supports the MySQL wire protocol.

History

BedRock is the system that backs Expensify, the expense management company. It had been used for 8 years prior to being launched. It was originally created as an in house solution to the strict database constraints of financial institutions - response time within milliseconds, transaction logging and authentication, and replication of multiple servers.

Data Model

Relational

Hardware Acceleration

Custom

Bedrock is written for modern hardware with SSD-backed RAID drives and RAM file caches. It was made to be "simple", not requiring any esoteric hardware hacks as done by other systems. Hence, there is no standard hardware acceleration option.
