Gld Configuration

• gld User Manual

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
  implementation: local

  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

  load-strategy:
    ...

implementation

Specifies either a conventional service implementation name, such as "local", or ... ?, or a fully qualified class name that can be looked up on the class path and instantiated.

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.

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.

Client Libraries Configuration

Client Libraries Available in the Operational Environment

TODO: replace with a real example

service:
  implementation:
    name: jboss-datagrid-7
    classpath: ${JDG_HOME}/client/hotrod.jar
...

Client Libraries Shipped with the gld Distribution

TODO: replace with a real example

service:
  implementation:
    name: jboss-datagrid-7
    version: 7.0.0
...
