Instance Attribute Details

#equal_databases ⇒ Object

type: Hash This comma-separated list of databases are equal. These database names are always considered to have the same tables. In other words, this makes database1.table1.chunk1 equal to database2.table1.chunk1 if they have the same checksum. This disables incremental processing, so you won’t see any results until all input is processed.

#master ⇒ Object

type: string The name of the master server. Specifies which host is the replication master, and sorts lines for that host first, so you can see the checksum values on the master server before the slave.
