asterisk users - Apr 2014 - Alembic - Asterisk 11

I've had years of experience using ODBC for CDR, SIP, and extensions with
Asterisk.  One thing that has been problematic in the past is with
documentation as far as database tables changing between versions (even
within minor releases, though that was back in the 1.4 days).  I was
excited to see there is a plan for better managing that on Asterisk 12 via
Alembic.  All that being said, are there any plans to implement that with
Asterisk 11, since that is the current LTS release?  Or are we pretty sure
the table structure won't be changing within that version through the rest
of its lifespan, making such an effort a waste?

Thanks,

Josh

There are no plans to implement Alembic in Asterisk 11. This is for a
few reasons:

(1) Asterisk 11 is an LTS and is already released. Simply introducing
Alembic at this time for it is potentially disruptive. Asterisk 12, as
a Standard release, was the appropriate place to introduce such a new
feature.

(2) Schema changes in Asterisk 11 are rare, and would only be done as
a result of a critical bug that absolutely required such a change.
Schema changes mid-release would be noted in the UPGRADE notes.
Asterisk 12, on the other hand, has limited support for new features.
Some of these new features - such as new parameters for the PJSIP
stack - require new database fields. As such, various schemas have
changed more frequently in this release; in this situation, Alembic is
far more useful.
