Subject Re: Better way to read several stream sources
Date Wed, 25 Jan 2017 09:34:36 GMT
Found the reason.
I saw using ParallelSourceFunction my override open() is called 4 times,
comparing to using sourceFunction open() is called only once, and my
override open() constructs the connection to sources, which determines how
many source are going to be read.

Cheers,

Sendoh
