Console stream sampling tool

Uses Reservoir stream sampling algorithm (see links below)

Can work with 3 different stream types:

• STDIN input stream
• Randomly generated stream
• Stream, aquired from URL

---

Usage

By default application runs in "random generated stream" mode

$ bin/sampling

To run application in other modes, you can use

$ bin/sampling run

And one of options below.

Options

Name	Description
--streamType	Type of stream, can be one of: RND, STDIN, URLStream
--samplingSize	Integer sample size
--url	Used only for 'URL streaming' mode

Example for url run

$ bin/sampling run --streamType URL --url https://www.random.org/integers/?num=10&min=1&max=6&col=1&base=10&format=plain&rnd=new

Example for STDIN run. For user interactive run you can type any amount of values and type "exit", when you done. Or just pipe values from another app.

$ bin/sampling run --streamType STDIN
