Gld Configuration

Configuration
-c <cofiguration-file.yml>
If the configuration file is not specified on the command line (where it has priority), it is looked up a value of GLD_CONF_FILE environment variable.
Load Configuration
service: ... load: threads: 10 requests|operations|messages: 1000 # optional, if not specified load will be generated forever
Cache Service Configuration
service:
type: cache
key-size: 10 # optional, if not specified, the default value is 12 characters
value-size: 1024 # optional, if not specified, the default value is 512 characters
implementation:

For details on how to configure a specific implementation, see Implementation below.

Generic Load Strategy Configuration
load-strategy: class: <fully-qualified-class-name>
read-then-write-on-miss Load Strategy Configuration
service:
type: cache
...
load-strategy:
name: read-then-write-on-miss
reuse-value: false
reuse-value
By default, the load strategy randomly generates the first entry value and then keeps reusing it, as a speed optimization (reuse-value: "true"). To change this behavior and configure the load strategy to generate a new random value every times it needs one, set "reuse-value" to "false". Configuring the load strategy to not reuse values will make it somewhat slower.
write-then-read Load Strategy Configuration
service:
type: cache
...
load-strategy:
name: write-then-read
reuse-value: false
read-to-write|write-to-read: <integer>
reuse-value
See reuse-value above.

write-to-read
Store Configuration
store: type: hierarchical directory: ../store # if relative, is relative to the position of the configuration file
Implementation
The implementation section defines the gld extension to use. The extension contains implementation-specific details essential to connect to, and interact with the target service.
Implementation Name
The implementation "name" specifies the name of the gld extension that will be instantiated. For more details about extension names, see "Extension Name" section.
service:
implementation:
name: <extension-name>
Implementation Class
Optionally, the implementation may be specified by its fully qualified class name:
service:
implementation:
class: some.fully.qualified.class.Name
Note that an implementation may be specified either by name or class, but not both. The configuration parsing will fail both the name and the class are found. The class, and its dependents, must be available on the extension class path.
