bytes written
[ https://issues.apache.org/jira/browse/AVRO-1203?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Thiruvalluvan M. G. resolved AVRO-1203.

A simple workaround using flush and getting the number of bytes from output stream has been provided.
> Support for obtaining the number of bytes written
> -------------------------------------------------
>
> Key: AVRO-1203
> URL: https://issues.apache.org/jira/browse/AVRO-1203
> Project: Apache Avro
> Issue Type: Improvement
> Components: c++
> Affects Versions: 1.7.2
> Reporter: Manuel Simoni
> Priority: Major
>
> I've used the Avro C++ library to implement Avro support for Node.js [1].
> In the course of this, I needed to extend the library so that it keeps
> track of the number of bytes written to a stream by an encoder.
> These changes mostly required making various headers public, and only
> small changes to implementation code.
> Here's a detailed list of changes:
> - Make the following headers public:
> -- BinaryEncoder.hh
> -- Symbol.hh
> -- ValidatingCodec.hh
> -- json/JsonDom.hh
> -- json/JsonEncoder.hh
> -- json/JsonIO.hh
> - Extend StreamWriter to keep track of number of bytes written (bytesWritten_, getBytesWritten())
> - Expose BinaryEncoder's and JsonEncoder's StreamWriter via getStreamWriter() method
> The complete changes can be viewed here on Github:
> https://github.com/manuel/avro-cpp/commit/f77c108a04fc9e39397eb2fae86b2710b64e2c8a
> The code is available in the "manuel/avro-cpp" Github Repo on the
> "upstream_submit" branch:
> https://github.com/manuel/avro-cpp/tree/upstream_submit
> We would love to have this functionality added to the Avro C++ library.
