Ensure the Distributed Transaction Mode Is Securely Configured

MediaNivel 1Automatizadatdsql

Descripción

TDSQL supports multiple distributed transaction modes, of which XA_TRANSACTION mode provides cross-shard ACID guarantees. Runs the mysql client against the SQLEngine (compute node) selected by TDSQL_SQLENGINE_OPTS (falls back to TDSQL_MYSQL_OPTS); keep the password in ~/.my.cnf or a login path.
