How do you update a value with a path in complex object in Redis/ReJson on Kubernetes?

Question

I am trying to update a complex object via a path value which it appear ReJson can do. I have used it as a Cache just fine, I want to use it as a json collection store for real time data (similar to mongodb).

for example: { "name": "Michael \u0027Mike D\u0027 Diamond", "employeeID": "E#101", "role": "Cleaner", "location": { "longitude": -2.552079, "lattitude": 51.501335 }, "numberOfAssignedJobs": 5 }

For example I want to update location.lattitude without taking the whole object and dealing with read/write sync issues.

However I am struggling with the API/How it is used in kubernetes. If anyone has any example code or tips and tricks, anything is much appreciated.

Thanks, Matt

You can do this with the JSON.GET command and JSON path syntax (docs here)

First, save the document in Redis at key "jsondoc":

127.0.0.1:6379> json.set jsondoc $ '{ "name": "Michael \u0027Mike D\u0027 Diamond", "employeeID": "E#101", "role": "Cleaner", "location": { "longitude": -2.552079, "latitude": 51.501335 }, "numberOfAssignedJobs": 5 }'

Atomically update path location.latitude to some other value:

127.0.0.1:6379> json.set jsondoc $.location.latitude 52.014
OK

Retrieve just location.latitude:

127.0.0.1:6379> json.get jsondoc $.location.latitude
"52.014"
