Manual:Suitability of tables for sharing/de

Some tables lend themselves better than others to being shared using $wgSharedTables .

Tabelle	Can be shared?	Anmerkungen
archive	Nein	ar_rev_id -Kollisionen
category	Nein	cat_title collisions
categorylinks	Nein	cl_from -Kollisionen
change_tag	Nein	ct_log_id collisions
comment	Nein	Houses comments linked to multiple unshareable tables.
externallinks	Nein	el_from -Kollisionen
filearchive	Nein	?
image	Nein	To have a shared media repository, see $wgForeignFileRepos
imagelinks	Nein	il_from -Kollisionen
interwiki	Ja	The interwiki table contains mostly static data; it may be useful to share if you have many custom interwikis.
ipblocks	Ja	By sharing the ipblocks table, you can have "global blocks" so that a block on one wiki will block the user or IP on all other wikis using the shared database. There can be some minor issues when sharing the ipblocks table. Viz., the ipb_reason field is set as the "reason" on Special:Block when blocking a user. When a blocked user sees the "You are blocked" message, this is parsed as wikitext, and links are parsed on Special:BlockList, you will need to make sure when blocking a user that the message makes sense on all wikis. Also, block logs will not be shared. (You must also share your user table for shared ipblocks to work.) Note that the comment table cannot be shared, which may cause issues with some blocking-related code, per phab:T214011.

transcache	?	?

user	Ja	A shared user table can be used to have multiple wikis that have shared user registrations, so that users need only sign up to one wiki. Siehe Handbuch:Gemeinsame Datenbank .
user_former groups	Ja	You would need to share the user table as well, and presumably user_groups.
user_groups	Ja	Sharing the user_groups table will allow you to have global user groups. As with the block log, the user rights log is not shared.

user_properties	Ja	By default, the user_properties table is included in the list of shared tables.
valid_tag	?	?
