How do you use handlersocket?

HandlerSocket is a MySQL plugin that offers developers a fast and cacheless way to access MySQL databases, allowing them to read and modify data directly without executing SQL statements.

The usage of HandlerSocket is as follows:

1. To install and configure the HandlerSocket plugin, start by installing the plugin and enabling it in the MySQL configuration file. Refer to the official HandlerSocket documentation for installation and configuration methods.
2. To establish a connection with HandlerSocket: In an application, it is necessary to create a connection with the HandlerSocket server. This can be done using a client library that supports HandlerSocket, such as the HandlerSocketi extension for PHP.
3. Open the index of HandlerSocket: Through the connection of HandlerSocket, you can open the index of one or multiple database tables. The index can be a combination of single or multiple fields. You can use the open_index() method of the connection to open the index.
4. Performing read and modify operations: Once the index is opened, you can utilize the connected execute() method to execute queries and modifications. Queries can be done by specifying values of index fields for range searches or exact searches. Modifications can update existing records or insert new ones.
5. Result processing: After performing a query or modification operation, you can use the read_result() method of the connection to retrieve the results. The results can be the entire record or the values of specific fields.

It’s important to note that HandlerSocket can only be used for executing simple queries and modifications, as it does not support complex SQL statements and transaction operations. Additionally, since HandlerSocket bypasses MySQL’s query cache and permission verification mechanism, it should be used with caution to ensure that only authorized users can access the database.
