Subject: About transformations
Dear guys,
We're performing some tests to evaluate the behavior of transformations and
actions in Spark with Spark SQL. In our tests, first we conceive a simple
dataflow with 2 transformations
xecution time was 11 seconds. Apparently, the results
of the transformations required by the first count were cached by Spark for
the second count.
Please, do you guys know what is happening?
