• Store & Forward Type
  • The type of the Store & Forward mechanism options: In_Memory and Disk_Backed (available in release 4.0.17 and higher)
  • Data stored with an In_Memory Store & Forward will not be persisted across a module configuration change, module disable/enable, module restart or power loss
  • Data stored with a Disk_Backed Store & Forward will persist across a module configuration change, module disable/enable, module restart or power loss
• Message Capacity - deprecated in 4.0.19
  • The maximum number of messages to store before dropping the oldest historical messages
• History Max Size
  • The maximum number of megabytes history can use before dropping the data
  • In_Memory Store & Forward will use the Ignition Java Heap memory

• Partition Key Count
  • The number of partition keys to use for inserts
• Partition Key
  • An optional partition key pattern that supports token substitution for the following message fields: ${group}, ${edgenode}, ${device}.  This should only be configured if explicitly defined partition keys are necessary when inserting into the Kinesis Stream.
• Max Message Size
  • The maximum message size in bytes to send. Generally, this should match the max message size allowed by AWS Kinesis.
