How to use ClientV2 and ExternalTable

[den-crane]

I need an example how to use ClientV2 and ExternalTable

For example I have a simple query select * from numbers(10) where number in ExternalTable;

        final Client client = new Client.Builder().setUsername("default").setPassword("").addEndpoint("http://localhost:8123/")
                .build();

        final String sql = "select * from numbers(10) where number in ExternalTable";
        QueryResponse response = client.query(sql).get(3, TimeUnit.SECONDS);
        ClickHouseBinaryFormatReader reader = client.newBinaryFormatReader(response);
        while (reader.hasNext()) {
            reader.next();
            System.out.println(reader.getLong("number"));
        }

And I need to pass 1\n\2\n3 as ExternalTable.

Like here

clickhouse-java/clickhouse-client/src/test/java/com/clickhouse/client/ClientIntegrationTest.java

Line 570 in bed84ee

try (ClickHouseResponse response = request

Or here #891

https://clickhouse.com/docs/engines/table-engines/special/external-data

I need it because I want to pass a list with 200k values and a query size (SQL length) without using the external data is bigger than 1Mb.

This is not supported in v2 currently. Will look into it short this week.
