74343: sql: use FastIntMap for QueryState.RangesPerNode r=nvanbenschoten a=nvanbenschoten This commit switches `QueryState.RangesPerNode` from a `map[roachpb.NodeID]int` to a `util.FastIntMap`. This avoids a pair of heap allocation as long as node IDs say below 32 and the number of ranges for each node stays below 14. ``` name old time/op new time/op delta KV/Scan/SQL/rows=1-10 94.5µs ± 4% 94.1µs ± 6% ~ (p=0.796 n=10+10) name old alloc/op new alloc/op delta KV/Scan/SQL/rows=1-10 20.1kB ± 0% 19.9kB ± 0% -0.84% (p=0.000 n=10+9) name old allocs/op new allocs/op delta KV/Scan/SQL/rows=1-10 245 ± 0% 243 ± 0% -0.82% (p=0.000 n=10+9) ``` ---- This is part of a collection of assorted micro-optimizations: - #74336 - #74337 - #74338 - #74339 - #74340 - #74341 - #74342 - #74343 - #74344 - #74345 - #74346 - #74347 - #74348 Combined, these changes have the following effect on end-to-end SQL query performance: ``` name old time/op new time/op delta KV/Scan/SQL/rows=1-10 94.4µs ±10% 92.3µs ±11% -2.20% (p=0.000 n=93+93) KV/Scan/SQL/rows=10-10 102µs ±10% 99µs ±10% -2.16% (p=0.000 n=94+94) KV/Update/SQL/rows=10-10 378µs ±15% 370µs ±11% -2.04% (p=0.003 n=95+91) KV/Insert/SQL/rows=1-10 133µs ±14% 132µs ±12% ~ (p=0.738 n=95+93) KV/Insert/SQL/rows=10-10 197µs ±14% 196µs ±13% ~ (p=0.902 n=95+94) KV/Update/SQL/rows=1-10 186µs ±14% 185µs ±14% ~ (p=0.351 n=94+93) KV/Delete/SQL/rows=1-10 132µs ±13% 132µs ±14% ~ (p=0.473 n=94+94) KV/Delete/SQL/rows=10-10 254µs ±16% 250µs ±16% ~ (p=0.086 n=100+99) name old alloc/op new alloc/op delta KV/Scan/SQL/rows=1-10 20.1kB ± 0% 19.1kB ± 1% -4.91% (p=0.000 n=96+96) KV/Scan/SQL/rows=10-10 21.7kB ± 0% 20.7kB ± 1% -4.61% (p=0.000 n=96+97) KV/Delete/SQL/rows=10-10 64.0kB ± 3% 63.7kB ± 3% -0.55% (p=0.000 n=100+100) KV/Update/SQL/rows=1-10 45.8kB ± 1% 45.5kB ± 1% -0.55% (p=0.000 n=97+98) KV/Update/SQL/rows=10-10 105kB ± 1% 105kB ± 1% -0.10% (p=0.008 n=97+98) KV/Delete/SQL/rows=1-10 40.8kB ± 0% 40.7kB ± 0% -0.08% (p=0.001 n=95+96) KV/Insert/SQL/rows=1-10 37.4kB ± 1% 37.4kB ± 0% ~ (p=0.698 n=97+96) KV/Insert/SQL/rows=10-10 76.4kB ± 1% 76.4kB ± 0% ~ (p=0.822 n=99+98) name old allocs/op new allocs/op delta KV/Scan/SQL/rows=1-10 245 ± 0% 217 ± 0% -11.43% (p=0.000 n=95+92) KV/Scan/SQL/rows=10-10 280 ± 0% 252 ± 0% -10.11% (p=0.000 n=75+97) KV/Delete/SQL/rows=10-10 478 ± 0% 459 ± 0% -4.04% (p=0.000 n=94+97) KV/Delete/SQL/rows=1-10 297 ± 1% 287 ± 1% -3.34% (p=0.000 n=97+97) KV/Update/SQL/rows=1-10 459 ± 0% 444 ± 0% -3.27% (p=0.000 n=97+97) KV/Insert/SQL/rows=1-10 291 ± 0% 286 ± 0% -1.72% (p=0.000 n=82+86) KV/Update/SQL/rows=10-10 763 ± 1% 750 ± 1% -1.68% (p=0.000 n=96+98) KV/Insert/SQL/rows=10-10 489 ± 0% 484 ± 0% -1.03% (p=0.000 n=98+98) ``` 74461: ci: additionally build go-test-teamcity in ci r=rail a=rickystewart It's used in examples-orms.

The assertion for this was wrong, it did not properly report the invalid situation to the client. We can't really test this - I was not able to find a single client that gets this wrong.
