MYSQL Mediumblob--mysql's Bolb four types

In MySQL, a blob is a binary large object, a container that can store large amounts of data, which can accommodate different sizes of data. The Blob type is actually a type family (Tinyblob, Blob, Mediumblob, Longblob) and they are equivalent except for the maximum amount of information stored.

MySQL four types of blobs

Type size (units: bytes)
Tinyblob Max 255
Blob Max 65K
Mediumblob Max 16M
Longblob Max 4G

In practice, you define different blob types based on the size of the data you need to deposit.
It is important to note that if you store too large a file, the performance of the database will degrade a lot.
