<div dir="ltr">There is a review for swift [1] that is requesting
to set the max header size to 16k to be able to support v3
keystone tokens. That might be fine if you measure you request
rate in requests per minute, but this is continuing to add
significant overhead to swift. Even if you *only* have 10,000
requests/sec to your swift cluster, an 8k token is adding almost
80MB/sec of bandwidth. This will seem to be equally bad (if not
worse) for services like marconi.

<div>When PKI tokens were first introduced, we raised concerns
about the unbounded size of of the token in the header, and
were told that uuid style tokens would still be usable, but
all I heard at the summit, was to not use them and PKI was the
future of all things.</div>

<div>At what point do we re-evaluate the decision to go with pki
tokens, and that they may not be the best idea for apis like
swift and marconi?</div>

Keystone tokens were slightly shrunk at the end of the last release
cycle by removing unnecessary data from each endpoint entry.<br>
<br>
Compressed PKI tokens are enroute and will be much smaller.<br>
