Nakul Jamadagni announces Databricks Runtime 5.2:
Delta Time Travel
Time Travel, released as an Experimental feature, adds the ability to query a snapshot of a table using a timestamp string or a version, using SQL syntax as well as DataFrameReader options for timestamp expressions.
Sample code
SELECT count() FROM events TIMESTAMP AS OF timestamp_expression
SELECT count() FROM events VERSION AS OF version
Time travel looks a bit like temporal tables in SQL Server.
