Databricks recommends regularly runningVACUUMon all tables to reduce excess cloud data storage costs. The default retention threshold for vacuum is 7 days. Setting a higher threshold gives you access to a greater history for your table, but increases the number of data files stored and, as a re...

Hist Hist now supports optional by-column histogram build, which is automatically configured based on various conditions of input data. This helps the XGBoost CPU hist algorithm to scale better with different shapes of training datasets. (#8233, #8259). Also, the build histogram kernel now can ...
