Notification of upcoming master/slave maintenance period - Monday, 16th July 2012 at 6-8pm (US/Pacific)

[Amy Unruh]

(If your application is already using the High Replication datastore,
you can ignore this email.)

We are scheduling a maintenance period that will impact applications
running on master/slave datastore:
Monday,16th July 2012 at 6-8pm (US/Pacific)

The master/slave datastore will be placed into a read-only period for
the duration of this maintenance, though we are targeting a shorter
read-only period.

Below is the information we usually send out with these
notifications.
It has more information about read-only periods, how to be notified of
production events and how to migrate your application to High
Replication.

----------
The master/slave datastore will be placed into read-only mode and
memcache will be flushed. It is recommended that critical portions of
your application that depend on the datastore should make use of the
capabilities API to detect and recover gracefully during read-only
periods.
Documentation describing the capabilities API can be found here:

Python: http://code.google.com/appengine/docs/python/howto/maintenance.html
Java: http://code.google.com/appengine/docs/java/howto/maintenance.html

There will be no downtime for developers whose applications use High
Replication Datastore. You can read more about High Replication here:

To migrate your master/slave application to High Replication while
preserving your application ID, you can use the migration tool that is
provided in the Admin Console. Read more about this tool here:

This maintenance period is starting, and the master/slave datastore is being placed into read-only mode.  We will update this thread again when the maintenance is complete.
