Mycat beta 0.3.0 released
+0 Vote Up -0Vote Down

After a very long time distracted with other projects, I finally added the third component of the MyCAT project: binlog_mon, a binary log manager for MySQL.

The main feature of this tool is that it has two disk usage thresholds which determine when it purges your binary logs:

  • a lower, "nominal", threshold above which binary logs will be purged if-and-only-if none of the replication slaves are still reading it,
