- bench: charge both arms of a rebinding case the rebinding, and add the null that can see it
#30opened by casey-bot· merged session 09-27 07:11
2 - perf: build a result set's rows once per result, not once per row
#29opened by drew-bot· merged session 09-27 01:43
4 - bench: keep every burst, and print rule 13's gauge beside the ratio
#28opened by drew-bot· merged session 09-27 01:26
1 - perf: give the rows of one result one instance dict, not one each (1.2x-1.6x on a 20000-row conversion, -344 bytes a row)
#27opened by drew-bot· merged session 09-26 21:43
8 - perf: materialise temporal and decimal Arrow columns through numpy (3.2x-3.4x on a result with a timestamp, a date and a decimal in it)
#25opened by drew-bot· merged session 09-26 20:04
9 - ci: give this repository a CI that runs (and fix the one red cell it found on 3.10)
#24opened by drew-bot· merged session 09-26 19:21
1 - perf: read the null bitmap a byte at a time, not a value at a time (1.2x-2.1x on a whole column-based response)
#23opened by avery-bot· merged session 09-26 16:20
4 - docs: correct the 4.7.0 timestamp notes, and say what the ValueError fallback is really for
#22opened by casey-bot· merged session 09-26 16:08
2 - perf: read a server timestamp with the standard library, not dateutil (26x on a whole column-based response, 40-72x on the parse)
#20opened by drew-bot· merged session 09-26 15:40
2 - fix: advance the read-ahead ramp only on steps that read something (50.8x -> 1.6x over-conversion when arraysize is raised mid-result)
#19opened by drew-bot· merged session 09-25 14:23
3 - docs: say that the columnar path's container type changes, like the Arrow layout does
#17opened by blake-bot· merged session 09-25 13:13
1 - perf: fetchone() converts a chunk of rows, not one row at a time (18.7x on `for row in cursor`)
#16opened by drew-bot· merged session 09-25 11:18
6 - perf: stop putting a zero-row chunk in every cloud-fetch result (1.18x-1.20x on a one-row conversion)
#14opened by avery-bot· merged session 09-24 23:50
2 - perf: check a column chunk's shape once per result set, not once per row (1.20x-1.22x on a columnar fetchone())
#13opened by drew-bot· merged session 09-24 22:46
1 - bench: a runnable harness for the v4.4.2 columnar shape guard
#11opened by drew-bot· merged session 09-24 21:58
1 - perf: stop re-deriving per-result-set facts on every fetchone() (1.7x on iteration)
#9opened by drew-bot· merged session 09-24 21:28
5 - perf: skip the pandas round-trip in the default arrow path when it is an expensive identity (1.5x-22x)
#5opened by drew-bot· merged session 09-24 20:26
2 - fix: keep a non-rectangular column chunk loud instead of losing columns
#4opened by drew-bot· merged session 09-24 18:46
1 - perf: build result rows column-wise (4.4x on _convert_arrow_table, 1.9x columnar)
