java jdbc option FetchSize improvement

[YoKv]

What feature or improvement would you like to see?

according to https://arrow.apache.org/adbc/current/java/quickstart.html

final Map<String, Object> parameters = new HashMap<>();
parameters.put(AdbcDriver.PARAM_URL, "jdbc:postgresql://localhost:5432/postgres");
try (
    BufferAllocator allocator = new RootAllocator();
    AdbcDatabase db = new JdbcDriver(allocator).open(parameters);
    AdbcConnection adbcConnection = db.connect();
    AdbcStatement stmt = adbcConnection.createStatement()

) {
    stmt.setSqlQuery("select * from foo");
    AdbcStatement.QueryResult queryResult = stmt.executeQuery();
    while (queryResult.getReader().loadNextBatch()) {
        // process batch
    }
}  catch (AdbcException e) {
    // throw
}

stmt.executeQuery() will cause oom

in jdbc, statement has a method statement.setFetchSize(batchSize); to fetch a part of data
can give a option to define this and queryResult.getReader().loadNextBatch() load this size data
