show pro/con overview:
**prometheus:**
* + you get nicer graphs with counters and bars if you ask me
* + you can use alertmanager if you want advanced alerting
* + optimized for timeseries data
* - not designed for keeping long timeseries (weeks or some months are fine)
* - not possible to import historical data
* - not as flexible as mysql regarding complex queries
**mysql**:
* + you can import your ALL.txt since 2019
* + you can store a lot of data over a long timeframe
* + you can propably build more complex queries in sql
* - in comparison to prometheus not optimized for timeseries, but still good enough
* - gauge based graphs are not as nice as counter/bars if you ask me
* - you can use *only* graphanas internal alerting

con:

both allow distributed setups with multiple wsjtx instances submitting their data to a central prometheus or mysql service.
you can as well run both in parallel and use prometheus for a live overview and mysql for historical evaluations.

### how long does it take to import my data into mysql?
* my ALL.TXT (new format start july 2019) contains ~ 13.7 mio lines and has ~ 850M
* converting to csv takes ~ 14min on i7-4750HQ (2015) and the result has ~ 1.2G
* converting to csv takes ~ 12min on i7-4750HQ (2015) and the result has ~ 1.2G
* currently this is done using another module which uses regular expressions which is not optimial for this use case
* importing the csv to mysql takes ~ 3.5min
* querying the whole time (~ 1.5 years) in grafana takes some seconds
