What are the pros and cons of handlersocket?

Handlersocket is a high-performance MySQL protocol plugin that offers a new way to access MySQL data. Here are its advantages and disadvantages:

Advantages:

1. High performance: Handlersocket bypasses MySQL’s query parsing and optimizer stages, directly manipulating the data engine to significantly improve query performance.
2. Low latency: Handlersocket is a protocol based on TCP/IP that, when compared to traditional MySQL protocol, can reduce the overhead of network transmission, thereby lowering query latency.
3. Lightweight: Handlersocket is a standalone plugin that does not require extra storage space or memory resources, making it suitable for use in environments with limited resources.
4. Easy to use: Handlersocket offers a simple API that allows developers to easily achieve high-performance database access.

Drawback:

1. Only basic SQL operations are supported: Handlersocket only supports basic query operations such as SELECT and UPDATE, it does not support complex SQL statements and transaction operations, so it may not meet the demands of some complex application scenarios.
2. Data integrity and constraints are not supported: Handlersocket directly manipulates the data engine, bypassing MySQL’s integrity and constraint checks, so developers need to handle data integrity and consistency issues themselves.
3. Configuration and deployment can be complex: Handlersocket requires configuration and deployment on the MySQL server, which may be challenging for some non-technical users.
4. Community support is limited: Handlersocket is not an official plugin provided by MySQL, so community support and documentation may be relatively limited.
