Denis Chudov updated IGNITE-19478:
----------------------------------
Description:
*Motivation*
There are multiple entities written to meta storage during DDL operations,
especially table creation, for example, assignments. The size of these entities
is excessive, because of usage instances of ClusterNode, wrapping to
collections and so on. This can lead to degradation in Raft during creation of
multiple tables, see IGNITE-19275 .
The size of such entities can be optimized.
*Definition of done*
The size of serialized entities is close to number of bytes which is taken by
elementary types which these entities consist of.
*Implementation notes*
We can use @Transferable annotation with OptimizedMarshaller to serialize table
entities.
