Chandni Singh commented on APEXMALHAR-2031:
-------------------------------------------
In Managed State this can be useful as follows:
Each Bucket contains a Meta file. This meta file contains certain information
about each TimeBucket- one such item is the last transferred window id.
So let's say Bucket 1-> TimeBucket1 has last transferred window id as 10. Now
if during transfer of window id 10 there was a failure and then the
application was re-started (cold).
If the window files are outside the older app's path, the new application can
see that window 10 was not deleted but Bucket1->TimeBucket 1 has window 10 as
last transferred window id. With this information it is certain that there was
a failure during transfer of this file and its data should be transferred to
the bucket data.
This will be a slight improvement.

> The Window Data Manager stores data in the application path, but some uses
> require the data to be stored in a user definable absolute path so that the

> This update is required for one of our users.
