Table Creation Limits per Instance

Each TDSQL Boundless instance has a limit on the number of tables it can create. This limit depends on the node specification and the number of nodes in the instance. If this limit is exceeded, the corresponding error code (EC_MC_CREATE_DATA_OBJ_TASK_MAX_TABLE_COUNT_EXCEEDED) will be returned.
