Service Components
The types of services which can be configured includes:
- ReplicatedCache - A cach service which maintains copies of all cache entries on all cluster nodes which run the service.
- ReplicatedCache.Optimistic - A version of the ReplicatedCache which uses optimistic locking.
- DistributedCache - A cache service which evenly partitions cache entries across the cluster nodes which run the service.
- SimpleCache - A version of the ReplicatedCache which lacks concurrent control.
- LocalCache - A cache service for caches where all cache entries reside in a single cluster node.
- InvocationService - A service used for performing custom operations on remote cluster nodes.
Elements
The following table describes the elements you can define for each service element.
| Element |
Required/Optional |
Description |
| <service-type> |

Specifies the canonical name for a service, allowing the service to be referenced from the service-name element in cache configuration caching-schemes. |
| <service-component> |
Required |
Specifies either the fully qualified class name of the service or the relocatable component name relative to the base Service component.
Legal values are:
- ReplicatedCache
- ReplicatedCache.Optimistic
- DistributedCache
- SimpleCache
- LocalCache
- InvocationService
|
| <use-filters> |
Optional |
Contains the list of filter names to be used by this service.
For example, specifying use-filter as follows
<use-filters>
<filter-name>gzip</filter-name>
