Using the Amazon Simple Queue Service (SQS), counts the number of messages in an Amazon SQS queue.
The performance of this transformer is dependent on the amount of memory allocated to the Java Virtual Machine (JVM). The following environment variables allow you to specify memory available to Java Plugins:
- FME_JVM_MIN_HEAP_SIZE: Initial heap size for initializing the JVM. Default value is 1024K.
- FME_JVM_MAX_HEAP_SIZE: Maximum heap size for initializing JVM. Default value is 16384K.
If unset, the JVM applies the default values. If set, the values must be multiples of 1024K (for example, 4M and 64M, or 4096K and 32768K).
Note: To pass additional parameters used by FME to the Java Virtual Machine, use the JAVA_TOOL_OPTIONS environment variable.
This transformer accepts any feature.
This transformer outputs all features that enter the transformer, plus the following attributes:
- sqs_count: The approximate total number of messages in the queue.
- sqs_count_visible: The approximate number of visible messages in the queue.

Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter.
