All three have different usecases. If you are looking for more of a
warehouse you are better off with Shark.
SparkSQL is a way to query regular data in sql like syntax leveraging
columnar store.
BlinkDB is a experiment, meant to integrate with Shark in the long term.
Not meant for production useca
Hi,
I have seen three different ways to query data from Spark
1. Default SQL support(
https://github.com/apache/spark/blob/master/examples/src/main/scala/org/apache/spark/sql/examples/HiveFromSpark.scala
)
2. Shark
3. Blink DB
I would like know which one is more efficient
Regard
