Bug ID: 33488
Summary: Branch transfer limits should have an index on
fromBranch
Change sponsored?: ---
Product: Koha
Version: master
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P5 - low
Component: Architecture, internals, and plumbing

In a consortium with many libraries, the branch transfer limits can become
complex and have many rows - we have seen 750k+
At this size, searching on limits can take 1/2 a second or more - and when a
record has many items this begins to add up fast
Adding an index to the fromBranch column greatly reduces the cost of a lookup:
CREATE INDEX fromBranch_index ON branch_transfer_limits (fromBranch);
