If I changed code like this, it works for me - connectionProvider = new ClickHouseConnectionProvider(options); to connectionProvider = new ClickHouseConnectionProvider(options, connectionProperties);

Hi @YahorBurakevich

Can you describe the scenario where you have to pass 'properties.*' to this temporary ClickHouse connection?

Hi, @itinycheng I need to use ssl mode for connect to Clickhouse. I passed properties.ssl = true

Ok, got it. Use new ClickHouseConnectionProvider(options, connectionProperties); seems more reasonable here. I'll find time to fix it.
