> The compression cache currently caches a single byte array for the
> CompressionInfo.db file, this is a problem for large files as it involves
> allocating and garbage collecting large memory segments, but also means that
> every consumer of the bytes will instantiate a CompressionMetadata object and
> allocate an individual BigLongArray to store the chunk offsets. This is
> unnecessary as the CompressionMetadata is immutable and can be re-used.
