> Project: IMPALA
> Issue Type: Bug
> Components: Docs
> Reporter: Alex Rodoni
> Assignee: Alex Rodoni
> Priority: Major
>
> I see this Kudu page [1] states that the "default" encoding for int8, etc
> are "bit shuffle"
> and this Impala page [2] states that AUTO_ENCODING: use the default encoding based on the column type; currently always the same as PLAIN_ENCODING, but subject to change in the future.
> I dug into some Kudu commands to try to view the actual data, and it seems that BIT_SHUFFLE is the correct answer for integer fields with no specific column encoding specified.
