smart_replace

Purpose​

smart_replace identifies values for smart replacement wherever they are encountered. For example, let's say we need to replace a set of unique user IDs spread throughout a large set of traffic. It would take a long time to meticulously define and replace each instance of the user ID. Instead, use smart_replace to match each user ID with a new value whenever it is encountered. Insert smart_replace at the beginning of a transform chain and the value being extracted will be matched with the new value at the end of the chain in the future.

Usage​

"type": "smart_replace",
"config": {
    "overwrite": "<boolean>",
}
  • overwrite - If false, the key=value mapping will be made permanently. If true, the key=value mapping will be rewritten each time smart_replace is called. This is helpful if you want to rotate values through a CSV continuously. For most use cases, overwrite=false (the default) is desired.

Example​

The smart_replace transform forms the heart of session or request ID replacement workflow.

Configuration​

"type": "smart_replace",
