KV Store

This application modifies the body in the onResponseBody function.

It ignores the body received from the origin and instead just replaces it with results from interacting with a KV Store.

Note This is purely to demonstate how to interact with a KV Store. It has no real world use case.

Application Flow

In onResponseHeaders it resets the content-length header, sets the transfer-encoding header and ensures that the runtime property response.content_type is set to application/json.
In onResponseBody it demonstrates how to interact with a KV Store.

This interaction with the KV Store is powered using query parameters.

store - the name of the store you wish to open. This is the name given to a store on the application.

action - What you wish to perform. Options are "get", "scan", "zscan", "zrange", "bfExists". ( If no action is provided it will default to "get" )

key - The key you wish to access in the KV Store.

match - A prefix match pattern, used by "scan" and "zscan". Must include a wildcard. e.g. foo*

min / max - Used by zrange for defining the range of scores you wish to receive results for.

item - Used by Bloom Filter exists function.
