Description Douglas Bagnall 2025-01-31 00:04:38 UTC 
samba-tool schemaupgrade and provision commands perform set-piece large transactions where we know a large index cache size will speed things up. 

In join, we use 

      options=['transaction_index_cache_size:200000']

and we can do that in these cases too.
