add command-line flag `-search.inmemoryBufSizeBytes` for configuring size of in-memory buffers used by vmselect during processing of vmstorage responses. A new summary metric `vm_tmp_blocks_inmemory_file_size_bytes` is exposed to show the size of the buffer during requests processing. The new setting can be used by experienced users to adjust memory usage by vmselect when processing many small read requests. Instead of allocating 4MB buffers each time, vmselect can be instructed to lower the buffer size via `-search.inmemoryBufSizeBytes`. To make the decision whether this flag needs to be adjusted users can consult with `vm_tmp_blocks_inmemory_file_size_bytes` which shows the actual size of buffers used during query processing. ---------- The detailed information of this PR can be found in https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6851 ### Checklist The following checks are **mandatory**: - [ ] My change adheres [VictoriaMetrics contributing guidelines](https://docs.victoriametrics.com/contributing/). --------- Co-authored-by: hagen1778 <roman@victoriametrics.com> |
