-----------------------------------------
Summary: Improve performance of TupleMarshaller
Key: IGNITE-22941
URL: https://issues.apache.org/jira/browse/IGNITE-22941
Project: Ignite
Issue Type: Improvement
Reporter: Konstantin Orlov
Assignee: Konstantin Orlov
Attachments: flamegraph.html
According to [^flamegraph.html], statistics gathering for buffer preallocation
takes ~78.9% (2.91% out of 3.69% of the whole graph) of an entire tuple
marshaling. Perhaps, it would be better to switch to best effort estimation,
and re-allocate buffer when we underestimate actual number of bytes required to
marshal the tuple.
