(was: auto-unassigned gsoc2016 mentor pull-request-available)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 60 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.

> The current implementation of the serializers can be a
> performance bottleneck in some scenarios. These performance problems were

> E.g. the PojoSerializer uses reflection for accessing the fields, which is
> slow [2].
> For the complete proposal see [3].
