not a question directly related to node-red, but I guess many people here might use influx databases.
So far I had influx data on an external usb stick. Since I now need that port for something else and generally the size of my database is small anyway, I want to store it to the SD card the system is running from (an old cubietruck)
Is it necessary/recommended to play with the
wal-fsync-delay or similar settings? Maybe even move the WAL to a ramdisk?
Although am I using a good and large SD card and never had issues so far, I think that it is just not right to write to the file system when ever a sensor reports a new value. Caching those in memory and doing writes every couple hours seems much more sensible.
