A Drop-in Middleware for Serializable DB Clustering across Geo-distributed Sites
Summary: Metric is a drop-in middleware providing strict-serializable, geo-distributed clustering for unmodified MariaDB/PostgreSQL services. It combines local DB performance with an entry-consistent redo log, delivering substantial latency and throughput gains over native clustering and geo-distributed DBs.
