Is anyone considering a new OLAP system these days? If “NewSQL” (which seems to be a fancy buzzword for running analytics in your transactional database) takes off wont it be the final nail in the coffin for OLAP?
"NewSQL" is not about analytical performance, it's about multimaster distributed writes and reads. EG, you don't want to run count(*) on spanner.
"HTAP" is the buzzword you're looking for. It's promising, but also complex and nascent. It'll be interesting to see how much traction it gets over time, but things like TiDB and Unistore are pretty early on to call a nail in the coffin for redshift/bigquery/clickhouse etc.
I think the opposite concept, "reverse ETL," is actually more popular. You put everything into your data warehouse and then pump whatever you need out from there.
Not if you expect to do a bunch of data transformation before you materialize it into one of these engines.. if the way you want a materialize it is materially different than the way you handle it transactionally you're going to be moving it anyway and if you're moving it why not put it into an optimized context
