Databricks Runtime 18: 18. Mai 2026
Databricks Runtime 18 bringt Verhaltensänderungen: CREATE OR REPLACE TABLE behält Kommentare, DataFrame-Schreibvorgänge nach Namen casten kompatible Spaltentypen automatisch, und ALTER TABLE SET TBLPROPERTIES für pipelines.pipelineId versucht, die Tabelle für Pipeline-Schreibzugriffe freizugeben.
Behavioral changes
Review the following changes, which take effect when clusters restart on this runtime.
CREATE OR REPLACE TABLE:CREATE OR REPLACE TABLEnow preserves existing column and table comments by default. Previously, comments were dropped when recreating a table. Managed tables and views now match the existing behavior of materialized views and streaming tables.- DataFrame by-name writes:
writeTo().append(),writeTo().overwrite(),writeTo().overwritePartitions(), andwrite.mode("append").saveAsTable()now automatically cast type-compatible columns (for example,inttolong) to match the target Delta table schema. Previously, these operations failed with aDELTA_FAILED_TO_MERGE_FIELDSerror when column types were compatible but not identical. Behavior now matches SQLINSERT INTO ... BY NAME.save()andsaveAsTable()in overwrite mode are not affected. ALTER TABLE SET TBLPROPERTIESforpipelines.pipelineId:ALTER TABLE <table> SET TBLPROPERTIES('pipelines.pipelineId' = '<pipeline-id>')now attempts to make the specified table eligible for writes by the pipeline. Previously, setting this property on a regular table had no effect. If the table isn't eligible for pipeline writes, the command throwsSETTING_PIPELINES_PIPELINE_ID_NOT_SUPPORTED. …
