Ah nice thanks Markus, however - different subsets of INSTALLED_APPS sounds a bit hacky, how would I do it anyway? checking in the settings which database is being migrated and providing a different list? Or any other way?
- MIGRATION_MODULES sounds a bit safer, but I'm not sure it gives the same advantage, since from my understanding django still has to go through all the apps for each db anyway right? >From my understanding the INSTALLED_APPS would be a much bigger performance gain right? thanks On Tuesday, October 25, 2016 at 4:29:45 PM UTC+1, Markus Holtermann wrote: > > Hi Andrea, > > If you have models that are entirely unrelated in different databases > you could use different values for INSTALLED_APPS to limit the apps > Django sees or by settings the values in the MIGRATION_MODULES dict to > None to tell Django that those apps don't have migrations. > > Cheers, > > /Markus > > On Tue, Oct 25, 2016 at 08:05:46AM -0700, andrea crotti wrote: > >We have a couple of databases with a tiny number of tables, but > >django-migrations has still go through all the migrations anyway. > >So even if the SQL itself is nothing it still takes a massive amount of > >time and memory for the usual known issues with migrations on big > projects. > > > >I guess it works this way because it only knows at run time in the router > >if something should be done, however it's a bit odd. > > > >If we declared the models per database somehow statically, could we not > >just skip everything else? > > > >-- > >You received this message because you are subscribed to the Google Groups > "Django users" group. > >To unsubscribe from this group and stop receiving emails from it, send an > email to django-users...@googlegroups.com <javascript:>. > >To post to this group, send email to django...@googlegroups.com > <javascript:>. > >Visit this group at https://groups.google.com/group/django-users. > >To view this discussion on the web visit > https://groups.google.com/d/msgid/django-users/f5340bbf-2247-4068-bd37-9f3a0faf23d4%40googlegroups.com. > > > >For more options, visit https://groups.google.com/d/optout. > > -- You received this message because you are subscribed to the Google Groups "Django users" group.
