=head1 NAME
RT::Shredder - Permanently wipeout data from RT
=head2 CLI
- rt-shredder --force --plugin 'Tickets=queue,general;status,deleted'
-
+ rt-shredder --force --plugin 'Tickets=query,Queue="General" and Status="deleted"'
=head1 DESCRIPTION
=head2 Web based interface (WebUI)
Shredder's WebUI integrates into RT's WebUI. You can find it in the
-Configuration->Tools->Shredder tab. The interface is similar to the
+Admin->Tools->Shredder tab. The interface is similar to the
CLI and gives you the same functionality. You can find 'Shredder' link
at the bottom of tickets search results, so you could wipeout tickets
in the way similar to the bulk update.
=head1 CONFIGURATION
-=head2 $RT::DependenciesLimit
+=head2 $DependenciesLimit
Shredder stops with an error if the object has more than
-C<$RT::DependenciesLimit> dependencies. For example: a ticket has 1000
+C<$DependenciesLimit> dependencies. For example: a ticket has 1000
transactions or a transaction has 1000 attachments. This is protection
from bugs in shredder from wiping out your whole database, but
sometimes when you have big mail loops you may hit it.
-Defaults to 1000.
+Defaults to 1000. To change this (for example, to 10000) add the
+following to your F<RT_SiteConfig.pm>:
-You can change the default value, in F<RT_SiteConfig.pm> add C<Set(
-$DependenciesLimit, new_limit );>
+ Set( $DependenciesLimit, 10_000 );>
=head2 $ShredderStoragePath
-Directory containing Shredder backup dumps.
+Directory containing Shredder backup dumps; defaults to
+F</opt/rt4/var/data/RT-Shredder> (assuming an /opt/rt4 installation).
+
+To change this (for example, to /some/backup/path) add the following to
+your F<RT_SiteConfig.pm>:
+
+ Set( $ShredderStoragePath, "/some/backup/path" );>
+
+Be sure to specify an absolute path.
+
+=head1 Database Indexes
-Defaults to F</path-to-RT-var-dir/data/RT-Shredder>.
+We have found that the following indexes significantly speed up
+shredding on most databases.
-You can change the default value, in F<RT_SiteConfig.pm> add C<Set(
-$ShredderStoragePath, new_path );> Be sure to use an absolute path.
+ CREATE INDEX SHREDDER_CGM1 ON CachedGroupMembers(MemberId, GroupId, Disabled);
+ CREATE INDEX SHREDDER_CGM2 ON CachedGroupMembers(ImmediateParentId,MemberId);
+ CREATE INDEX SHREDDER_CGM3 on CachedGroupMembers (Via, Id);
+ CREATE UNIQUE INDEX SHREDDER_GM1 ON GroupMembers(MemberId, GroupId);
+
+ CREATE INDEX SHREDDER_TXN1 ON Transactions(ReferenceType, OldReference);
+ CREATE INDEX SHREDDER_TXN2 ON Transactions(ReferenceType, NewReference);
+ CREATE INDEX SHREDDER_TXN3 ON Transactions(Type, OldValue);
