Configuration recommendations
checkpoint_timeout=15min
- when a lot of data is ingested, increase the checkpoint timeout to reduce the input/output pressure.bgwriter_lru_maxpages=100000
- increase the number of pages a background writer can handle, to make it more efficient.- - this does not cause data corruption or inconsistency. However, in case of a crash, some of the most recent data points could be lost. For a monitoring observability use case, it’s a reasonable trade-off to increase ingest performance.
