Inside the UDS deduplication index

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

The UDS index is at the center of the deduplication capability of the
dm-vdo device mapper target. The UDS index holds the metadata that
allows dm-vdo to find duplicate blocks quickly with minimal storage
overhead. The index is highly optimized to take advantage of common
properties of real world data sets. This might be useful in other data
processing environments besides block storage as in dm-vdo.

This presentation will explore the inner workings of the UDS index and
the tradeoffs that lead to effiency but also determine what it can and
cannot do.
