>Subject: [PATCH] Bug 36033: Add more indexes to table
> pseudonymized_transactions
>
>Table pseudonymized_transactions contains :
>  KEY `pseudonymized_transactions_ibfk_1` (`categorycode`),
>  KEY `pseudonymized_transactions_borrowers_ibfk_2` (`branchcode`),
>  KEY `pseudonymized_transactions_borrowers_ibfk_3` (`transaction_branchcode`)
>
>To improve SQL queries performance, it needs more indexes, specially on itemnumber.
>
>Looking at table statistics :
>  KEY `timeidx` (`datetime`),
>  KEY `branch_idx` (`branch`),
>  KEY `type_idx` (`type`),
>  KEY `itemnumber_idx` (`itemnumber`),
>
>So index is need on pseudonymized_transactions columns :
>itemnumber => For join with table items
>transaction_type => For filter on type issue, return ...
>datetime => For filter on date, this will help cleanup script
>
>Test plan :
>1) Run updatedatabase.pl
>2) Check indexes are created in table pseudonymized_transactions
>3) Run SQL query :
>   describe select * from pseudonymized_transactions join items using(itemnumber)
>   where transaction_type='issue' and datetime < date_sub(curdate(), INTERVAL 30 DAY)
>=> You see the 3 new indexes used in 'possible_keys'.
