The main purpose of this command-line flag is to increase the lifetime of low-end flash storage with the limited number of write operations it can perform. Such flash storage is usually installed on Raspberry PI or similar appliances. For example, `-inmemoryDataFlushInterval=1h` reduces the frequency of disk write operations to up to once per hour if the ingested one-hour worth of data fits the limit for in-memory data. The in-memory data is searchable in the same way as the data stored on disk. VictoriaMetrics automatically flushes the in-memory data to disk on graceful shutdown via SIGINT signal. The in-memory data is lost on unclean shutdown (hardware power loss, OOM crash, SIGKILL). Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3337 |
