Hi all,
I am trying to learn about UDAF and implemented a simple reservoir sample
UDAF. It's working fine. However I am not able to figure out what DataType
should I use so that its can deal with all DataTypes (simple and complex).
For instance currently I have defined my input schema as
def
Hi Ritesh,
Right now, we only allow specific data types defined in the inputSchema.
Supporting abstract types (e.g. NumericType) may cause the logic of a UDAF
be more complex. It will be great to understand the use cases first. What
kinds of possible input data types that you want to support and
hi Yin,
I have a written a simple UDAF to generate N samples for each group. I am
using reservoir sampling algorithm for this. In this case since the input
data type doesn't matter as I am not doing any kind of processing on the
input data but just selecting them by random and building an array
