-----------------------------------------
Summary: Sql. Improve conversion to BinaryRow in UpdatableTableImpl
Key: IGNITE-21019
URL: https://issues.apache.org/jira/browse/IGNITE-21019
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Konstantin Orlov
As for now, {{UpdatableTableImpl}} uses {{RowAssembler}} to re-assemble row
prior to send it to the table. The problem here is this is not very efficient
because of number of reasons. First, the most simple constructor of
{{RowAssembler}} is used, this causes tuple builder to preallocate 4kb of
buffer, which sometimes is too much. Second, usage of {{RowAssembler}} implies
double (de-)serialization since every field should be read from source row and
write back to target tuple.
Given that sql row now natively supports to binary tuple conversion, depending
on the schema of a table we may reuse that binary tuple or reshuffle fields
avoiding deserialisation by reading raw bytes.
