The largest valid size of a single table is only constrained by the largest file size allowed by the operating system.
The storage capacity of an RDS MySQL instance can reach up to 2 TB. Therefore, the largest size of a single table is slightly less than 2 TB due to overheads of metadata. If an RDS MySQL instance has more than one table, the total size of these tables cannot exceed 2 TB.
