Bryan Boreham	3b57ad2a54	WAL: remove ePool that is unused (#8669) ... **What this PR does / why we need it**: Nothing is ever fetched from the pool - `GetEntries()` is never called. And the loop to call `PutEntries()` follows a call where the slice it ranges over is reset to empty, so that loop never added anything to the pool. **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - NA Documentation added - NA Tests updated - NA `CHANGELOG.md` updated - NA Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md`	3 years ago
Bryan Boreham	08ac5336d5	WAL: store pointers in record pool (#8667) ... **What this PR does / why we need it**: Storing a slice in `sync.Pool` wastes 24 bytes every time it is returned to the heap; see https://staticcheck.io/docs/checks#SA6002 Storing a pointer to a slice allows the Pool to work without waste. This came up in discussion about the benchmark in #8489 - with this change the memory usage comes down: ``` name old time/op new time/op delta Writer_WriteEntries/1000_lines,_1_different_label_sets-4 7.37ms ±13% 7.45ms ± 9% ~ (p=0.841 n=5+5) name old alloc/op new alloc/op delta Writer_WriteEntries/1000_lines,_1_different_label_sets-4 727kB ± 0% 679kB ± 0% -6.63% (p=0.008 n=5+5) name old allocs/op new allocs/op delta Writer_WriteEntries/1000_lines,_1_different_label_sets-4 12.0k ± 0% 10.0k ± 0% -16.68% (p=0.000 n=5+4) ``` **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - NA Documentation added - [x] Tests updated - NA `CHANGELOG.md` updated - NA Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md`	3 years ago
