Overview
After a sync task is started, if there are too many connections to the source database or the business needs to be adjusted, you can pause the task and resume it after the business adjustment is completed.
Application scope
Data sync links among MySQL, TDSQL-C for MySQL, MariaDB, and Percona.
Notes
Only sync tasks in Running status can be paused.
After a task is paused, DTS will continue to pull the data and binlog of the source database but will not write data to the target database. After the task is resumed, DTS will continue the task based on the binlog data points before the pause.
During sync, binlog records are retained for up to seven days. If the pause lasts longer than seven days, the task will fail and cannot be restarted. We recommend that you keep the pause period below three days.
Because DTS continues to pull the data and binlog of the source database during the task pause, billable links will still be billed when the sync task is paused.
Directions
1. Log in to the DTS console, select Data Sync on the left sidebar, select the target sync task, and click Pause in the Operation column. 2. In the pop-up window, confirm that everything is correct and click OK.
