This article is about how to set up cache in mysql. Xiao Bian thinks it is quite practical, so share it for everyone to make a reference. Let's follow the editor and have a look.

The cache setting method in mysql: 1. Enable the self cache function [show variables like "%cache%"];2. Set the self cache to 32M [set global query_cache_size = 1024 * 1024 * 32;].

Methods of caching settings in mysql:

1. You need to enable MySQL's own cache function

# show variables like "%cache%"

query_cache_type: MySQL's own cache startup state is enabled by default, but there is no space size

query_cache_size: Size of MySQL's own cache, in bytes

If you need to set MySQL's own cache to 32 MB

# set global query_cache_size = 1024 * 1024 * 32;

Run some comparative tests.

query_cache_size=0;

3. Inquiry

4. Open MySQL cache (32 MB space)

5. When modifying the case of words in a query statement, the query result remains unchanged, but MySQL's own cache considers this to be a different query and will cache it here (MySQL's own cache is strictly based on the case of sql statements).
