Hi,
I have a PR open [1] to add a DataFrame/Table style API for building a
logical query plan. So far I only added a couple methods to it, but here is
a usage example:
let t = ctx.table("aggregate_test_100")?;
let t2 = t
.select_columns(vec!["c1", "c2", "c11"])?
.limit(10)?;
This builds the same logical plan as "SELECT c1, c2, c11 FROM
aggregate_test_100 LIMIT 10".
Adding more methods is mostly trivial but I wanted to get this initial PR
merged first so that I can add new methods as small separate PRs.
I'd appreciate some reviews if anyone has the bandwidth.
Thanks,
Andy.
