Performance: How to increase loading speed when access dcc.Store data from callback

[jinnyzor]

Hello @DeKhaos,

Have you looked into serversude caching for the storages? Browsers limit the amount of data you can store there to about 8mb, plus the network traffic that you use would be pretty big.

Show and Tell - Server Side Caching

The Store component in Dash makes it easy to share state between callbacks. Under the hood, the data are stored as JSON in the browser. This approach is chosen to keep the server stateless (i guess), but it has a few drawbacks As the data are stored in JSON, you must convert objects from/to JSON in the beginning/end of each callback Since the callbacks are executed server side while the data are stored client side, the data will be sent across the wire every time a callback is invoked The maxi…

See side caching would eliminate the need to transfer the data.
