perf: preallocate in Assign #484

pmalek · 2024-06-30T11:22:19Z

Heuristically preallocate in Assign.

Assumption is that Assign is typically called with maps with different keys. For this invocations the benefit is the greatest.

Worst case scenario is when all the keys in all the merged maps are the same. The allocations for those calls are unnecessary but the execution time is roughly the same.

The preallocation factor can be decreased to e.g. half the count of all the entries in all the provided maps to try to cover both mentioned scenarios.
