Databricks Connect for Databricks Runtime 15.3

Databricks Connect 15.3.0 (Scala)

July 22, 2024

Features and improvements:

• Supported Dataset.observe for getting stats of Columns of a DataFrame. See SPARK-47545.
• Added a new function timestamp_add for adding the specified number of units to the given timestamp. See SPARK-48369.
• Added a new function timestamp_diff for getting the difference between the timestamps in the specified units by truncating the fraction. See SPARK-48272.
• Added a new function try_mod for computing the remainder of the division of two numbers, which results in null on division by zero. See SPARK-48954.
• Added a new function try_parse_json, which attempts to parse a JSON string and construct a Variant value. If the attempt fails, the result is null. See SPARK-47922.
• Changed the default value for spark.sql.legacy.timeParserPolicy from EXCEPTION to CORRECTED. Instead of raising an INCONSISTENT_BEHAVIOR_CROSS_VERSION error, CANNOT_PARSE_TIMESTAMP will be raised if ANSI mode is enabled. NULL will be returned if ANSI mode is disabled. See SPARK-47719.

Databricks Connect 15.3.1 (Python)

July 18, 2024

Bug fixes:

• The behavior of df.column() in Spark Connect is now more aligned with the behavior in classic Apache Spark. Seehttps://issues.apache.org/jira/browse/SPARK-45509.
• Referencing the join column in df.drop() resolves correctly, instead of generating an "ambiguous column" error code. Seehttps://issues.apache.org/jira/browse/SPARK-45770.
• An object of Struct type can now be converted to XML using the to_xml() method. Seehttps://issues.apache.org/jira/browse/SPARK-44790.
