Modifying and Deleting a Memory Acceleration Rule

A memory acceleration rule can enable automated data synchronization from MySQL to GeminiDB. You can also modify and delete this rule.

Precautions

  • Currently, only hashes from MySQL can be converted to GeminiDB Redis API.
  • If a table name of the MySQL instance in the memory acceleration rule is changed, you need to reconfigure the rule.
  • Currently, the ENUM, SET, and JSON data cannot be synchronized.
  • If you rename or delete one or more key fields of a memory acceleration rule, the rule becomes invalid.
