I believe is it not the actual situation in bol.com. If it is, I would be disappointed.
Last I remember, Bol.com has really good set of ops and dev tooling on hadoop, hbase, spark, flink etc. for scheduling, running jobs etc.
I wouldn't know why they replicated data both on hbase, elastic search etc. Having read the blog, I don't see how this fits the event sourcing pattern that bol.com was trying to implement and also, the idea of self service BI that they envisioned.
I was one of them. I don't work there anymore.
