## zlib-plugin¶

### zlib_save¶

All of the object storage back ends should be set up to compress index-bundle objects. Typically, gzip -6 compression is used, though other compression algorithms are possible. The Zlib plugin configuration documentation gives a list of the algorithms that are currently supported.

Example Setting:

zlib_save = gz


### zlib_save_level¶

All of the object storage back ends should be set up to compress index-bundle objects. Typically, gzip -6 compression is used. The level parameter must always be from 1 to 9.

Example Setting:

zlib_save_level = 6
