What are the characteristics of the mediumtext type in MySQL?

Some features of mediumtext in MySQL include the following:

1. Large storage capacity: the mediumtext field can store text data with a maximum length of 16MB.
2. Character-set independent: The mediumtext field stores binary data that is not related to any character set, allowing it to store any type of data, including text, images, audio, and more.
3. The following types of fields can be indexed: character fields and mediumtext, which can improve query efficiency.
4. Does not take up extra storage space: The storage space for the mediumtext field is dynamically allocated and will only occupy the actual size of the data stored, without taking up any additional storage space.
5. Support full text search: You can use the full text search function to search and match text data in the mediumtext field.
6. String operations can be performed on mediumtext fields, such as truncating, replacing, and concatenating.

It is important to note that the large storage space of the mediumtext field may affect the performance of queries and writes when storing a large amount of data. Therefore, it is important to choose accordingly based on specific needs and scenarios.
