Konstantin Orlov created IGNITE-20813:
-----------------------------------------
Summary: Sql. Introduce InternalSqlRow as resulting row of
QueryProcessor
Key: IGNITE-20813
URL: https://issues.apache.org/jira/browse/IGNITE-20813
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Konstantin Orlov
As for now, the method signature of
{{QueryProcessor#querySingleAsync}} looks like this:
{code:java}
CompletableFuture<AsyncSqlCursor<List<Object>>> querySingleAsync(
SqlProperties properties,
IgniteTransactions transactions,
@Nullable InternalTransaction transaction,
String qry,
Object... params
);
{code}
The problem is that client code may not need de-serialised row right here right
now (for instance, thin client handler will send those rows down the channel
anyway), yet current signature force us to do deserialisation from a storage
format.
Let's change the signature to return something that extends InternalTuple, but
also provides a way to get column value by having only index of column of
interest (e.g. {{@Nullable Object get(int idx)}}).
