-----------------------------------------
Summary: Refactoring of tuple marshaller
Key: IGNITE-21506
URL: https://issues.apache.org/jira/browse/IGNITE-21506
Project: Ignite
Issue Type: Improvement
Reporter: Konstantin Orlov
At the moment, tuple marshaller (see
{{org.apache.ignite.internal.schema.marshaller.TupleMarshallerImpl}}) follow
the IEP-54 strategy, implying that table row is split on two chunk, and every
chunk is marshalled separately one after another. Although it creates byte-wise
equal table row, the approach is questionable because now we have no chunks,
and columns both of key and value are marshalled in a common space. Besides,
segregation on two chunks make it harder to get rid of IEP-54 leftovers
completely, because in fact key and value columns should not necessary take
contiguous space (meaning that layout `val1, id1, val2, id2' is valid)).
Let's simplify tuple marshaller in order to reflect actual state of the project
and prepare ground to completely get rid of IEP-54.
