[keycloak-dev] SingleFileExportProvider always tries to export users

[Marek Posolda]

The only reason is, that singleFile provided can have support just for 
some subset of usersExportStrategy options (REALM_FILE and SKIP). The 
others doesn't makes sense for singleFile provider as it always uses 
same file.

Originally the singleFile export/import provider was intended to be used 
just for small environments with small number of users, where you just 
quickly export everything into single file and you are good.
For environments with big number of users where more flexibility is 
needed, you would use either dir provider or zip provider (which was 
later removed because nobody was using it and it required additional 3rd 
party dependency). So the support for usersExportStrategy and also for 
"pagination" (limiting number of users in each transaction) was added 
just to those providers.

Feel free to create JIRA for support usersExportStrategy and pagination 
for singleFile provider.

Until we have it, you can use dir provider. Or is it something which 
blocks you from using dir provider?
