GlobalCache
GlobalCache implements a wrapper around go-cache for Flogo.
go-cache is an in-memory key:value store/cache similar to memcached that is suitable for applications running on a single machine. Its major advantage is that, being essentially a thread-safe map[string]interface{} with expiration times, it doesn't need to serialize or transmit its contents over the network.

Inputs
| Input | Description |
|---|---|
| action | The action to perform on the cache. Allowed values are INITIALIZE (to create a new GlobalCache object), SET (to add a new key/value pair to the cache), GET (to retrieve an object from the cache), and DELETE (to remove on object from the cache) |
| key | The name of the key to look for (during a GET or DELETE operation) or to add to the cache (during a SET operation) |
| value | The value to add to the cache |
| expiryTime | The expiration time of items in the cache in minutes (defaults to 5). Using -1 as expiryTime means items will never expire |
| purgeTime | The purge time of expired items in the cache in minutes (defaults to 10) |
| loadset | A JSON object representing key/value pairs to load while initializing the cache (like {"key":"value","retgits":"Awesome!"}) |
Ouputs
| Output | Description |
|---|---|
| result | The value of the item in the cache, if it exists (will return an empty element if no entry was found) |

Package globalcache implements a wrapper around go-cache for Flogo. go-cache is an in-memory key:value store/cache similar to memcached that is suitable for applications running on a single machine. Its major advantage is that, being essentially a thread-safe map[string]interface{} with expiration times, it doesn't need to serialize or transmit its contents over the network.
