This can be particularly useful when working with custom ClickHouse functions or extensions that require specific configuration parameters. By defining custom options, you can ensure that your client is properly configured to interact with these custom components. The flexibility of ClickHouseOption makes it a valuable tool for adapting your ClickHouse client to a wide range of scenarios and use cases. Whether you're working with a small-scale application or a large-scale data warehouse, ClickHouseOption provides the means to fine-tune your client's behavior to meet your specific needs. For instance, in a high-volume data ingestion scenario, you might use ClickHouseOption to increase the batch size for data insertion, thereby improving overall throughput. In a security-sensitive environment, you might use ClickHouseOption to enforce strict authentication policies and encryption protocols. By carefully considering your application's requirements and leveraging the power of ClickHouseOption, you can optimize your ClickHouse client for maximum performance, security, and reliability.

Practical Examples

Let's look at some practical examples to illustrate how ClickHouseOption can be used in real-world scenarios. Suppose you want to configure your ClickHouse client to connect to a server with a specific hostname and port, using a particular username and password. You can achieve this using ClickHouseOption as follows:

ClickHouseClient client = ClickHouseClient.builder()
 .option(ClickHouseOption.HOST, "your_clickhouse_host")
 .option(ClickHouseOption.PORT, 9000)
 .option(ClickHouseOption.USER, "your_username")
 .option(ClickHouseOption.PASSWORD, "your_password")
 .build();

In this example, we're using the ClickHouseClient.builder() method to create a new client instance and then using the option() method to specify the desired configuration settings. We're setting the HOST, PORT, USER, and PASSWORD options to their respective values. This ensures that the client will connect to the specified ClickHouse server using the provided credentials. Another common use case for ClickHouseOption is configuring connection timeouts. Suppose you want to set a timeout of 10 seconds for establishing a connection to the ClickHouse server. You can do this as follows:

ClickHouseClient client = ClickHouseClient.builder()
 .option(ClickHouseOption.CONNECT_TIMEOUT, 10000) // 10 seconds in milliseconds
 .build();

In this example, we're setting the CONNECT_TIMEOUT option to 10000 milliseconds, which is equivalent to 10 seconds. This ensures that the client will automatically disconnect if it fails to establish a connection within 10 seconds. These are just a few simple examples, but they illustrate the power and flexibility of ClickHouseOption. By using ClickHouseOption, you can easily customize your ClickHouse client to meet the specific needs of your application.
