Subject [jira] [Commented] (LUCENE-5739) Add zig-zag encoding support to DataInput/DataOutput
Date Thu, 05 Jun 2014 17:51:01 GMT

Adrien Grand commented on LUCENE-5739:
--------------------------------------

I know there is a long history of discussions around supporting negative values in {{writeVLong}}
but I think it would be nice so that the whole long range could be readable/writable with
zig-zag encoding?

> It would be convenient to have support for zig-zag-encoded integers in DataInput/DataOutput.
There are not many places that use that feature today but I think it's quite common to need
to read/write small signed values.
