I believe there are other people thinking about these
topics as well, including Andres Freund, Kyotaro Horiguchi, and
probably some folks at 2ndQuadrant (but I don't know exactly who).
1. asynchronous execution
Not looking at that.
2. vectorized execution...
We might also want to consider storing batches of tuples in a column-optimized
rather than row-optimized format so that iterating through one or two
attributes across every tuple in the batch touches the minimal number
of cache lines.
Team is about 2 years into research and coding prototype on those topics at this point, with agreed time for further work over next 2 years.
I'll let my colleagues chime in with details since I'm not involved at that level any more.
