Enabling/Disabling Read/write Separation

Operation Scenarios

TencentDB for Redis supports read/write separation for business scenarios with more reads but less writes, which can well cope with read requests concentrating on frequently read data. It supports up to 1-master 5-slave mode to offer 5x read performance.

  • Enabling read/write separation may cause data read inconsistency (the data on replica nodes are older than that on the master node). Please check whether your business can tolerate data inconsistency first.
  • Disabling read/write separation may interrupt existing connections momentarily, so you are recommended to do so during off-peak hours.


  1. Log in to the TencentDB for Redis Console and click an instance name on the instance list page to enter the instance management page.
  2. Select Manage Database > Manage Account and click Read-Only Replica to enable read/write separation.
  3. In the pop-up dialog box, confirm that everything is correct and click OK.
