Does rt-table only support spark now?

Hi,

I have investigated hudi, run some demos.
From the samples, it supports hive external realtime-table whose
InputFormat is HoodieRealtimeInputFormat, and the data is MergeOnRead.
But when I used presto to query, it throws error:
"HoodieRealtimeRecordReader can only work on HoodieRealtimeFileSplit and
not with ..."
Does rt-table only support spark, not support presto.

Thanks,
Kaka Chen

Hi Kaka,

That is correct. The real time view has been tested only on Hive and Spark
atm.
I believe Presto could be supported. But needs some work. Happy to explore
it if you are interested.

Thanks
