--------------------------------
[~bryanc] Thanks for the update!
Is there any thing particular needs to be done for StructType? Seems it has
been handled:
https://github.com/apache/spark/blob/master/sql/core/src/main/java/org/apache/spark/sql/execution/vectorized/ArrowColumnVector.java#L318
https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/arrow/ArrowWriter.scala#L63
> Complete support for remaining Spark data types in Arrow Converters
> -------------------------------------------------------------------

> Key: SPARK-21187
> URL: https://issues.apache.org/jira/browse/SPARK-21187
> Project: Spark
> Issue Type: Umbrella
> Components: PySpark, SQL
> Affects Versions: 2.3.0
> Reporter: Bryan Cutler
>
> This is to track adding the remaining type support in Arrow Converters.
> Currently, only primitive data types are supported. '
> Remaining types:
> * -*Date*-
> * -*Timestamp*-
> * *Complex*: Struct, Array, Map
> * *Decimal*
> Some things to do before closing this out:
> * Look to upgrading to Arrow 0.7 for better Decimal support (can now write
> values as BigDecimal)
> * Need to add some user docs
> * Make sure Python tests are thorough
> * Check into complex type support mentioned in comments by [~leif], should we
> support mulit-indexing?
