[Wikidata-bugs] [Maniphest] [Commented On] T177486: [Tracking] Wikidata entity dumpers need to cope with the immense Wikidata growth recently

[hoo]

hoo added a comment.

While T178247: Use a retrieve only CachingEntityRevisionLookup for dumps will certainly make the dumps much faster, it will only do so (noticeably) on HHVM. This is because we split the cache between HHVM and Zend (see below), thus the (currently) Zend dumpers wont profit from the cache which is probably mostly populated in the HHVM version of the cache (as all app server run HHVM).
There are some other maintenance scripts using Zend which might also write into this cache… so maybe this will still help something, though.

if ( defined( 'HHVM_VERSION' ) ) {
        // Split the cache up for hhvm. T73461
        $wgWBSharedCacheKey .= '-hhvm';
}
