Replication & High Availability
6 resources — subcategories Replication & High Availability
binlogsum
A summarizer for decoded MySQL and MariaDB binary logs — turns mysqlbinlog output into per-table write statistics, GTID/transaction ranges, and writes-over-time histograms for diagnosing replication delay and unusual write activity.
Canal
Alibaba's MySQL binlog subscribe-and-consume component — it disguises itself as a MySQL replica to pull and parse binlog events for real-time data sync, cache invalidation, and search-index updates.
Galera Cluster
A synchronous multi-master replication library for MySQL, MariaDB, and Percona Server — every node accepts reads and writes, with no replication lag and no lost transactions on failover.
gcache-inspector
An offline reader for Galera's write-set cache (GCache) files on Percona XtraDB Cluster and MariaDB Galera Cluster, summarizing per-table activity and decoding write-sets into row-level output without a database connection.
orchestrator
A MySQL replication topology discovery, visualization, and failure-detection tool with a CLI, HTTP API, and web UI, maintained by Percona as a continuation of the original openark/orchestrator project.
Percona XtraDB Cluster
A synchronous, multi-master MySQL clustering solution built on Galera replication, developed by Percona as a high-availability alternative to standalone MySQL.
