=head1 DESCRIPTION |
21
|
|
|
|
|
|
|
|
22
|
|
|
|
|
|
|
This plugin provides the ability to make stores silently fail |
23
|
|
|
|
|
|
|
read and write operations. This can be useful for migrating |
24
|
|
|
|
|
|
|
from one store to another where it doesn't make sense to write |
25
|
|
|
|
|
|
|
to the old store, only read. |
