Querying and Downloading Binlogs (OBT)

Binlogs record all DDL and DML statements (except data query statements). You can download binlogs to a local PC for further analysis.

This section describes how to enable binlog, and then query and download binlogs on the TaurusDB console.

Billing

Binlogs are stored in OBS buckets.

Prerequisites

  • Binlog can only be enabled when the following conditions are met:
    • If the kernel version of your DB instance is earlier than 2.0.45.230900, the value of log-bin must be ON. To view and modify the parameter value, see Modifying a Parameter Template.
    • If the kernel version of your DB instance is 2.0.45.230900 or later, the value of rds_global_sql_log_bin must be ON.
  • Before viewing and downloading binlogs, you need to enable binlog by referring to Enabling Binlog.

Constraints

To use binlogs, set the log-bin or rds_global_sql_log_bin parameter to ON.
