Local context storage not intended for large data arrays?

I just found this post:
https://discourse.nodered.org/t/persistent-context-storage/37858/2

by setting

contextStorage: {
        default: {
        module: 'memory'
        },
        disk: {
           module: 'localfilesystem', config: {flushInterval: '600'},
          },
     },

I can keep it all in memory, but flush to disk at the end of every cycle with:

flow.set("my_object", content, "disk")

That will do the trick
