Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog.

[0.6] - 2017-07-16

Added

• Support shipping anonymous objects that appear in inline-java quasiquotes. You'll need to configure your app to use the Kryo serializer for this to work. See FAQ in README. This fixes #104.

Changed

• Move parallelize, textFile and binaryRecords to Context module.
• Functions such as sample now use the [choice][hackage-choice] library to describe the semantics of boolean arguments in their types.
• Use inline-java for RDD bindings under the hood.

[0.5] - 2017-02-21

Added

• Bind to expm1
• Add bindings to dayofmonth, current_timestamp and current_date.
• Add support for the dataframe condition expressions
• Add bindings to withColumnRenamed, columns, printSchema, Column.expr.
• Bind DataFrame distinct.
• Add bindings for log and log1p for Columns.
• Add binding to Column.cast.
• Add bindings getList and array for columns.
• Add bindings: schema for rows, Metadata type, javaRDD, range, Row getters and constructors, StrucType constructors, createDataFrame, more DataType bindings.

Changed

• Prevent Haskell exceptions from escaping apply.
• Update sparkle to work with latest jni which uses ForeignPtr for java references.
• Move StructType and friends to modules StructField, DataType and Metadata.
• Rename createRow, rowGet, rowSize, joinPairRDD to have the same names as the java methods.

[0.4]

Added

• Support for reading/writing Parquet files.
• More RDD method bindings: repartition, treeAggregate, binaryRecords, aggregateByKey, mapPartitions, mapPartitionsWithIndex.
• More complete DataFrame support.
• Intero support.
• stack ghci support.
• Support Template Haskell splices and ANN annotations that use sparkle code.

Changed

Fixed

• More reliable initialization of embedded shared library.
• Cleanup temporary files properly.

[0.3] - 2016-12-27

Added

• Dockerfile to build sparkle.
• Compatibility with singletons-2.2.
• Add the identity Reify/Reflect instances.
• Change JNI bindings to use new JNI.String type, instead of ByteString. This new type guarantees the invariants required by the JNI API (null-termination in particular).

Changed

• Remove Reify/Reflect instances for Int. Only instances for sized types remain.

Fixed

• Fix type in Reify Int making it incorrect.

[0.2.0] - 2016-12-13

Added

• New binding: getOrCreateSQLContext.

Changed

• getOrCreate renamed to getOrCreateSparkContext.

[0.1.0.1] - 2016-06-12

Added

• More bindings to more call*Method JNI functions.

Changed

• Use getOrCreate to get SparkContext.

[0.1.0] - 2016-04-25

• Initial release
