Question: Availability of max_query_size Flag in Chproxy

Question details
In our use case with ClickHouse, we often encounter the need to pass larger queries. While the max_query_size flag works seamlessly with ClickHouse directly, we've encountered errors when using it with Chproxy. Can someone confirm whether the max_query_size flag is available in Chproxy?

Additional context/motivations
The max_query_size parameter is supported by ClickHouse within Query statements, aiding in the handling of larger queries.

indead you can use this flag. One way to have it in chproxy is to write it in the clickhouse query using the SETTINGS keyword. For example: select * from system.numbers limit 1 settings max_query_size= 400, would it solve your issue?
