Kevin Oliver commented on AVRO-355:
-----------------------------------
One proposal is to fix the seed to a constant for all runs. Another is to allow
users to specify a value as a flag to the tool. I don't have a preference.
> io.Perf test harness uses different random number seeds for each run

> Key: AVRO-355
> URL: https://issues.apache.org/jira/browse/AVRO-355
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.3.0
> Reporter: Kevin Oliver
> Priority: Minor
>
> Each java.math.Random that is created in io.Perf uses the default seed which
> is based on the current time of your environment. This makes comparing two
> different runs of the tool less comparable as it varies the number of
> multi-byte variable length encoded numbers that are generated from run to
> run.
