Subject Re: Tungsten + Flink
Date Fri, 01 May 2015 15:01:31 GMT
I don't think it's useful to combine them since they are different 
projects. But I do think that a lot of work went into Flink's paged 
memory system built on byte buffers and if collaboration can take place 
to pop that out into like a memory subsystem library that both Spark and 
Flink can use then it should raise both ships. If the usage patterns are 
too different then sure, don't use their work. But it looks pretty generic:

https://github.com/apache/flink/tree/master/flink-core/src/main/java/org/apache/flink/core/memory

To bring this back into other threads: Flink's memory system uses 
java.nio - so it requires Java 1.7 afaik. :)
