Subject Re: Flink on Tez
Date Sun, 09 Nov 2014 10:50:27 GMT
Thanks Kostas fir the reply.
I've already read your first post and what is not fully clear to me is the
technical motivation of. "Tez follows design choices that are geared
towards resource elasticity, whereas the design choices behind Flink's
engine are geared more towards low latency querying and iterative
processing".  Since in the future I could have to choose one of the 2 I'd
like to better understand the pros and the cons of the 2 runtimes.

Thanks in advance,
Flavio
