Question 1

How to sync MySQL data to Elasticsearch with go-mysql?

Accepted Answer

Use the Canal package to dump and incrementally sync binlog events, implementing a custom handler to push data to Elasticsearch; refer to the go-mysql-elasticsearch project for a complete example.

Question 2

go-mysql vs go-sql-driver/mysql: which is better for my project?

Accepted Answer

Choose go-mysql if you need low-level protocol access, replication, or custom server building; use go-sql-driver/mysql for standard database/sql operations with broader community support and simplicity.

Question 3

How to handle large SELECT queries without memory issues?

Accepted Answer

Use the streaming feature in the client package by calling ExecuteSelectStreaming with a callback function, which processes rows incrementally without loading the entire result set into memory.

Question 4

Can go-mysql work with MySQL 8.0 authentication methods?

Accepted Answer

Yes, the server package supports authentication methods like caching_sha2_password, and the client is tested with MySQL 8.0.x, ensuring compatibility with modern MySQL versions.

Question 5

What are the steps to build a MySQL proxy using this library?

Accepted Answer

Implement a fake MySQL server with the server package to intercept client commands, then add custom logic for routing or transforming queries, as demonstrated in the minimal server example.

Question 6

Is go-mysql compatible with ARM architectures?

Accepted Answer

Yes, as a pure Go library, it supports ARM64 and ARM architectures, with testing confirmed on Linux for production use, though 32-bit ARM lacks continuous integration.
