I notice that Neil's patch regarding reducing the number of memory
allocations during aggregation operations isn't mentioned. It was
originally discussed in 8.0beta (2-3?) time.
What happened there?
- patch not committed in the end
- committed but not mentioned, as a dropped item
- committed but not mentioned, since part of a larger patch
Seemed like a good performance gain to me...
I *have* tried to find this, but Neil's work on memory allocation has
been extensive... (please take the compliment...).
