Built-in LRU memory cache provider

  1. Global Cache Xorm implements cache support. Defaultly, it’s disabled. If enable it, use below code.
cacher := xorm.NewLRUCacher(xorm.NewMemoryStore(), 1000)
engine.SetDefaultCacher(cacher)

If disable some tables’ cache, then:

engine.MapCacher(&user, nil)
  1. Table’s Cache If only some tables need cache, then:
cacher := xorm.NewLRUCacher(xorm.NewMemoryStore(), 1000)
engine.MapCacher(&user, cacher)

Caution:

  1. When use Cols methods on cache enabled, the system still return all the columns.

  2. When using Exec method, you should clear cacheļ¼š

engine.Exec("update user set name = ? where id = ?", "xlw", 1)
engine.ClearCache(new(User))
