Hi flink.
Im happy to announce that ive done a small bit of initial hacking on
bigpetstore-flink, in order to represent what we do in spark in flink.
TL;DR the main question is at the bottom!
Currently, i want to generate transactions for a list of customers. The
generation of transactions is a
Hi Jay!
You can use the "fromCollection()" or "fromElements()" method to create a
DataSet or DataStream from a Java/Scala collection. That moves the data
into the cluster and allows you to run parallel transformations on the
elements.
Make sure you set the parallelism of the operation that you wa
awesome thanks ! i ll try it out.
This is part of a wave of jiras for bigtop flink integration. If your
distro/packaging folks collaborate with us - it will save you time in the
long run, because you can piggy back the bigtop infra for rpm/deb
packaging, smoke testing, and HDFS interop testing
Hi Robert!
I did some debugging and added some tests. Turns out, this is actually
expected behavior. It has to do with the splitting of the records.
Because creating the splits happens without knowing the contents, the split
can be either in the middle of a record, or (by chance) exactly at the

Hi Kim and Stephan
Kim's report is sorting 3360GB per 1427 seconds by Flink 0.9.0. 3360 =
80*42 ((80GB/per node and 42 nodes)
Based on Kim's report. The TPS is 2.35GB/sec for Flink 0.9.0
Kim was using 42 nodes for testing purposes. I found that the best Spark
performance result was using
Hi Jiang,
Please refer to http://sortbenchmark.org/.
When you take a look at the specification of each node Spark team uses,
you can easily realize that # of nodes is not the only thing to take into
consideration.
You miss important things to consider for a fair comparison.

Hi Michael and George
First of all, congratulation you guys have won the sort game again. We are
coming from Flink community.
I am not sure if it is possible to get your test environment to test our
Flink for free. we saw that Apache spark did a good job as well.
We want to challenge yo
