  • MySQL: Streaming of BLOBS is better than storing them?
    MySQL: Streaming of BLOBS is better than storing them?
    Streaming BLOBs is indeed better than direct storage because it reduces memory usage and improves performance. 1) By gradually reading and processing files, database bloat and performance degradation are avoided. 2) Streaming requires more complex code logic and may increase the number of I/O operations.

  • MySQL: String Data Types and Collations
    MySQL: String Data Types and Collations
    The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

  • MySQL: What length should I use for VARCHARs?
    MySQL: What length should I use for VARCHARs?
    The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
