Assignee: Reuven Lax (was: Kenneth Knowles)
> Potential issue with QuantileStateCoder
> ---------------------------------------
>
> Key: BEAM-4667
> URL: https://issues.apache.org/jira/browse/BEAM-4667
> Project: Beam
> Issue Type: Bug
> Components: sdk-java-core
> Reporter: Zhiheng Huang
> Assignee: Reuven Lax
> Priority: Minor
>
> [https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/transforms/ApproximateQuantiles.java#L687]
> The line above encodes the QuantileState buffers.size() as if it's
> numBuffers. This seems wrong since before buffers are full, buffers.size() is
> not equal to numBuffers. One thing I suspect will happen is that, if we
> serialize before buffer is full, it will effectively reduce the number of
> buffers we maintain after deserialization.
