The Beam Java API for Calcite SqlTransform is no longer experimental (). Python's ParDo (Map, FlatMap, etc.) transforms now suport a `withexceptionhandling` option for easily ignoring bad records and implementing the dead letter pattern. `ReadFromBigQuery` and `ReadAllFromBigQuery` now run queries with BATCH priority by default. The `query_priority` parameter is introduced to the same transforms to allow configuring the query priority (Python) (). added to `ReadFromBigQuery`. The newly introduced `method` parameter can be set as `DIRECT_READ` to use the Storage Read API. The default is `EXPORT` which invokes a BigQuery export request. (Python) (). fields when using `ReadFromBigQuery`. This parameter can only* be used when `method = DIRECT_READ`(Python) (). Upgrade to Calcite 1.26.0 (). Added a new `dataframe` extra to the Python SDK that tracks `pandas` versions we've verified compatibility with. We now recommend installing Beam with `pip install apache-beam[dataframe]` when you intend to use the DataFrame API (). Add an of deploying Python Apache Beam job with Spark Cluster SQL Rows are no longer flattened (). ). was fixed. It used to silently pass incorrect null data read from JdbcIO. Pipelines affected by this will now start throwing failures instead of silently passing incorrect data. Fixed error while writing multiple DeferredFrames to csv (Python) (). Fixed error when importing the DataFrame API with pandas 1.0.x installed (). Fixed top.SmallestPerKey implementation in the Go SDK (). Large Java BigQueryIO writes with the FILE_LOADS method will fail in batch mode (specifically, when copy jobs are used). This results in the error message: `IllegalArgumentException: Attempting to access unknown side input`. Please upgrade to a newer version (> 2.34.0) or use another write method (e.g. `STORAGEWRITEAPI`). According to git shortlog, the following people contributed to the 2.34.0 release.
