Performance issue: Index needed on contribution_id field in cdntaxreceipts_log_contributions
Created by: lolaslade
I found that part of the underlying performance problem is due to this issue: We need an index on the contribution_id field in cdntaxreceipts_log_contributions. Even without using the hooks the "Receipts not issued" report is running into problems until I add this index. It will help with a number of the other queries in the extension as well. There are quite a few joins on this field.
