Question

I'M working on an application that the server retrieves currency

rates from a third-party-api and saves it in its database; for the purpose of real-time chart plotting. The challenge is to provide rate series for different intervals (e.g., 4 hours, 1 day, weekly, monthly) while saving rates every 5 to 8 seconds. To avoid overwhelming data transmission, I calculate the average within each interval.

Is this a database problem? e.g. there is Influxdb for time series DB but I haven't done comprehensive research on it, or this is both algorithm and database choice one.

My tech stack comprises TypeScript, Prisma, MySQL, and Nest.js.

Compact the data on insert, accumulating on the smallest unit you will display, e.g day will hold total for that day
