Compression
|
|
~~~~~~~~~~~
|
|
|
|
bcachefs supports gzip, lz4 and zstd compression. As with data
|
|
checksumming, we compress entire extents, not individual disk blocks -
|
|
this gives us better compression ratios than other filesystems, at the
|
|
cost of reduced small random read performance.
|
|
|
|
Data can also be compressed or recompressed with a different algorithm
|
|
in the background by the rebalance thread, if the
|
|
``background_compression`` option is set. |
