Bucket seems like a rather good name for it. The method for generating
could be Hash, running sequence modded, etc. So HashBucket,
RoundRobinBucket, etc.

Take a look at Phoenix(https://github.com/forcedotcom/phoenix). It supports
both salting and fuzzy row filtering through its skip scan.

Phoenix restricts salting to a single byte.
Salting perhaps is misnamed, as the salt byte is a stable hash based on the
row key.
Phoenix's skip scan supports sub-key ranges.
We've found salting in general

Hi Stack,
Thanks for info. Then how is it usually done with time-based keys? General
recommendation is prepend timestamp with something random prefix to shard
table properly.
But what if I want to scan table for certain time range? Scan whole table,
skipping random prefix and filter by time
of key.
For keys there are ColumnPrefixFilter and ColumnRangeFilter.
