      • MySQL/TDSQL-C for MySQL/TDSQL for MySQL/PostgreSQL: the storage space of the target database needs to be at least 1.2 times the size of the tables to be migrated in the source database.
      • MongoDB: the storage space of the target database needs to be at least 1.3 times the size of the tables to be migrated in the source database.
    • Check description: full data migration will execute INSERT operations concurrently, generating data fragments in some tables of the target database. Therefore, after full migration is completed, the size of the tables in the target database may be larger than that in the source database.
