All Implemented Interfaces:

Closeable, AutoCloseable, BinaryManager

public class SQLBinaryManager
extends CachingBinaryManager

A Binary Manager that stores binaries as SQL BLOBs.

The BLOBs are cached locally on first access for efficiency.

Because the BLOB length can be accessed independently of the binary stream, it is also cached in a simple text file if accessed before the stream.
