Known Causes
4 known causesInsufficient Server Resources
The MySQL server may lack sufficient CPU, memory, or disk I/O resources to perform data compression, especially under heavy load.
Corrupt Data or Table Issues
Underlying data corruption within a table or issues with the table's structure, particularly for compressed tables, can prevent successful compression.
Filesystem or Disk Problems
Problems with the underlying filesystem, such as insufficient disk space, write errors, or incorrect file permissions, can lead to compression failure.
Underlying Compression Library Errors
Issues within the compression libraries utilized by MySQL (e.g., zlib) or their interaction with the operating system can cause compression operations to fail.
