This directory is involved with the Kafka pipeline which needs an overarching rework, along with the stuff that feeds the pgehres database. I hope that if I become educated about what is going on there a more direct solution(s) will present itself, as it seems like analytics have a lot of tools at their disposal.
Also basic things like version control (I think some or all of it may be here: https://github.com/wikimedia/wikimedia-fundraising-tools/) and a deploy script (that repo gets put in /srv/tools but I don't see reference to /srv/br, don't know what the relationship is there)
@Ejegg @CCogdill_WMF @Pcoombe - can anyone tell me, is the stuff in this dir the main source of queries to the pgehres db? If not what else? And what other dbs does /srv/br query? Thanks in advance :)
