Telegraf retention policy

I just wondered if I understood the retention policy and if this scenario is good practice.
let’s say I have telegraf on N servers as an agent to collect logs (IIS ,eventViewr …)
I will create 3 retention policy’s

  1. Default for long term query.
  2. 7d for week long query.
  3. 1d for real time.

By doing that I will replicate the data and iterate on lees data per query?

@miki_haiat Telegraf just writes to one database by default. If you would like to perform downsampling on your raw data we have a guide here!
