Assessment

Before changing shards, you need to carry out a preliminary evaluation and determine the number of new shards, whether to scale up the current DDM node class, and the number of required data nodes and their specifications.

  • Data volume: Run show db status to query the volume of data involved.
  • DDM node class: Determine nodes of the DDM instance and vCPUs and memory size of each node.
  • Data node class: Determine the number of data nodes and vCPUs and memory size of each node.
  • Business scale: Analyze current service scale and growth trend.
