The MySQL Blackhole storage engine is a unique engine that does not store any data. Instead, it discards any data that is inserted into it and always returns an empty result set for SELECT queries. So why would anyone use it? The Blackhole engine can be useful in a few specific situations. For example, you might use it to capture and discard slow query log data, or to route certain types of queries to a separate server or application. It can also be used as a placeholder for a real storage engine, or as a way to “blackhole” or discard certain types of data. However, it’s important to note that the Blackhole engine is not a general-purpose storage engine and should not be used as the primary storage engine for your data. It is designed for specific use cases where data does not need to be stored, and its limited functionality makes it unsuitable for most applications. Creating a Blackhole-Engine Table To use the Blackhole engine, you must create a Blackhole engine table in your MySQL database. You can do this using the CREATE TABLE statement, with the ENGINE option set to BLACKHOLE: Once you have created a Blackhole-engine table, you can use it just like any other table in MySQL. However, any data you insert into it will be discarded, and SELECT queries will always return an empty result set.
