# Cache: Reuse the results from previous execution for custom tasks. | ||
|
||
### How To | ||
|
||
1. Setup. | ||
```go | ||
taskCacheStore := TaskCacheStore{} | ||
err := taskCacheStore.Connect(db.ConnectionParams{DbDriver: "sqlite3", DbName: ":memory:"}) | ||
// Currently, mysql and sqlite3 are supported driver. | ||
``` | ||
|
||
2. Store an entry to cache. | ||
```go | ||
taskCache := &model.TaskCache{ | ||
TaskHashKey: cacheKey, | ||
TaskOutput: cacheOutput, | ||
} | ||
taskCacheStore.Put(taskCache) | ||
``` | ||
|
||
3. Fetch an entry from cache. | ||
```go | ||
cacheResult, err := taskCacheStore.Get(taskCache.TaskHashKey) | ||
if err != nil { | ||
fmt.Printf("%v", err) | ||
} | ||
|
||
``` | ||
4. Prune entries older than a day using: | ||
```go | ||
taskCacheStore.PruneOlderThan(time.Now().Add(-24*time.Hour)) | ||
``` |
