Updated Key/Value Store Modules
In the previous versions of the Key/Value Store modules you could set/get and delete complex objects for a specific key in a Key/Value Store. What was not possible is to set/get or delete a specific part of such an object.
We have updated the Key/Value modules to allow users to access a specific property with a ‘path’ and perform specific actions such as set/get and delete only a specific property for a given key.
Beside that, template syntax is now supported on the ‘key’ and ‘path’ setting and warnings can be ignored if ‘key’ or ‘path’ were not found.
Example:
Store current state of machine in Key/Value Store from streaming ingest like OPC UA Subscription.
Key Value Set configuration:
Key = {data.machine} Path = {data.name} Value = data.value
Incoming message 1:
{ "crosser": { "success": true }, "data": { "machine": "blender_1", "name": "temp", "value": 17.7938298 } }
Incoming message 2:
{ "crosser": { "success": true }, "data": { "machine": "blender_1", "name": "pressure", "value": 0.99938298 } }
Incoming message 3:
{ "crosser": { "success": true }, "data": { "machine": "blender_1", "name": "speed", "value": 34.7938298 } }
Get all values for specific machine.
Key/Value Get configuration:
Key = {name} Path =
Result:
{ "crosser": { "success": true }, "data": { "pressure": 0.99938298, "speed": 34.7938298, "temp": 17.7938298 }, "name": "blender_1", "path": "" }
Get specific value utilizing ‘path’
Key = {name} Path = {path}
Result:
{ "crosser": { "success": true }, "data": 17.7938298, "name": "blender_1", "path": "temp" }
Tip: You can now also ignore module warnings in case the key and path is not found.
