If the data you are ingesting cannot be read due to some corruption issue, you can skip corrupted files by setting ignoreCorruptFiles to true in the FORMAT_OPTIONS: COPY INTO my_tableįORMAT_OPTIONS ('ignoreCorruptFiles' = 'true') After data is inserted into the table with COPY INTO, the table is queryable. You cannot use INSERT INTO and MERGE INTO to write data into schema-less Delta tables. The empty Delta table is not usable outside of COPY INTO. The preceding SQL statement is idempotent and can be scheduled to run to ingest data exactly once into a Delta table. You can now create empty placeholder Delta tables so that the schema is later inferred during a COPY INTO command: CREATE TABLE IF NOT EXISTS my_table

You can use VACUUM to remove the deleted files from physical storage, including the old files that contain dropped columns and have been rewritten by REORG TABLE. You can use REORG TABLE APPLY (PURGE) to trigger a file rewrite on the files that contain any soft-deleted data such as dropped columns. The columns are effectively “soft-deleted,” as they are still in the underlying Parquet files but are no longer visible to the Delta table. You can use ALTER TABLE DROP COLUMN or ALTER TABLE DROP COLUMNS (, *) to drop a column or a list of columns, respectively, from a Delta table as a metadata-only operation. Support for dropping columns in Delta tables (Public Preview) For example, SELECT * EXCEPT (x.a) FROM table returns all of table’s columns but omits field a from struct x. For example, SELECT * EXCEPT (x) FROM table returns all of table’s columns except x. SELECT statements now support the EXCEPT clause to exclude columns from selection. SQL: New EXCEPT clause in SELECT statement excludes columns from selection To get the previous behavior, which does not throw an error if the constraint does not exist, you must now use the IF EXISTS statement. If you now try to drop a Delta table constraint by name, and that constraint does not exist, you will get an error. Dropping a missing Delta table constraint now raises an error Use this new function to query version-related information. The new current_version function outputs the current Databricks Runtime version if available, the current Databricks SQL version if available, and other related version details. SQL: New current_version function outputs version details For example: - Describe an external location. You can now use DESC as an alias for DESCRIBE when you describe external locations or storage credentials. When the Azure Blob File System (ABFS) client uses a Shared Access Signature (SAS) token, the HTTPS scheme is now enforced. HTTPS scheme now enforced when ABFS client uses SAS token It preserves the INT96 timestamp format when using PolyBase and COPY commands for both batch and streaming workloads. The Azure Synapse connector now writes Parquet data in non-legacy mode. Synapse connector now writes Parquet data in non-legacy mode You can now use ipywidgets to make your Databricks Python notebooks interactive. In Databricks Runtime 11.0 and above, Python notebooks use the IPython kernel to execute Python code. Python notebooks now use the IPython kernel CONVERT TO DELTA in now supported in Unity Catalog enabled environments (Public Preview)ĭatabricks Runtime 11.0 and Databricks Runtime 11.0 Photon include Apache Spark 3.3.0.Support for dropping columns in Delta tables (Public Preview).SQL: New EXCEPT clause in SELECT statement excludes columns from selection.Dropping a missing Delta table constraint now raises an error.SQL: New current_version function outputs version details.HTTPS scheme now enforced when ABFS client uses SAS token.Synapse connector now writes Parquet data in non-legacy mode.Python notebooks now use the IPython kernel.Databricks released these images in June 2022.
