    Description

      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
      • Binary
      • Categorical when converting from Pandas

      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?
