Right-hand inserts and optimizer reports

edited April 2020 in General Discussion

In financial businesses, all data represents some kind of time series, and the time and date columns grow constantly. All my tables partitioned by date, and each day, I add a new partition.

Analyze calculates the min/max for each column, but optimizer sometimes detects a value outside of today's range, and will sometimes misreport that only a few rows will be fetched, rather than the tens of billions that I would expect. Optimizer wants to broadcast a huge table. What's the best way to resolve this?
