Improve consumer

[agranjeon]

Is your feature request related to a problem? Please describe.
Feels like the consumer is a bit dumb and reading each of the .info file every 20 seconds until the commit is processed seems a bit too much

Describe the solution you'd like
Maybe read it once, save the UNIX date in a map that map the date to the filename so we only have to check the variable instead of the whole files every 20 seconds
