cp sample.env .env

3. Run the script:

node --env-file=.env index.js

SQL Usage Example

with age as (select t1."issueId",t1.destination as status, sum(age(t2.timestamp, t1.timestamp)) as duration
from transitions t1
inner join transitions t2 on t1.destination = t2.source and t1."issueId" = t2."issueId" group by t1."issueId", status)
select status, extract(epoch from percentile_disc(0.5) within group (order by duration)) / 86400 AS age_in_days 
from age
where status in ('Ready for dev', 'Doing', 'Tech/Func Review', 'Deployed on Integration', 'Deployed on Recette') and extract(epoch from duration) > 0
group by status 
order by position(status::text in 'Ready for dev, Doing, Tech/Func Review, Deployed on Integration, Deployed on Recette');
