Hello,
I’m writing a memory sensitive application, and I want to know approximately what the marginal size of adding an additional UTF-8 encoded character to the db is. Specifically, if I write a character with a UTF code less than 128, does it require the same disk space as a character with a UTF code greater than 128? Is it approximately 1 byte per character?
Any insight would be appreciated. Thank you
Hello @Kamyar_Ghiam ,

Hello,
among FAQ I found the following info: “InfluxDB stores all integers as signed int64 data types.”
Does it mean that if I save a 1 byte variable, it will be take 8 bytes (before the compression)?

Hi. Like many, I am evaluating influxdb for an IoT sensor logging product, but my use case is to run the DB and store the data locally to the device and not to the cloud. The long-term TSM storage will likely be an SD card. (Still deciding where WAL should go.) One of the easiest ways to keep the SD card from wearing out is to store a small file size compared to the overall space on the card, which gives the SD card’s wear leveling algorithms lots of room to work with. So I’m very intereste…
Hello,
I was wondering how i could estimate the size of the index (RAM usage) based on tag set.
First of all, is there a formula or a tool to simulate index size or ram usage ?
Then, here is my use case :
I have informations that will probably need to be a tag (type of measure taken & unit used), but i might have 350 entries in this “type_of_measure” tag, for each robot, with maybe a 100 robots.
Based on UTF-8 encoding, here is what i estimated for tags & ram usage:
Robot_id : about 10 cha…
Ah yes those threads are helpful. Thanks!
