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 i…

I went ahead and slightly modified the /pages example to try and highlight the issue. app.py: from dash_extensions.enrich import ( Dash, FileSystemStore, ) import dash import dash_bootstrap_components as dbc import dash_labs as dl # Setup file caching fss = FileSystemStore(cache_dir="ca…

Hello all, I have a simple question for the usage of ServersideOutput. Is it necessary to convert all instances of Input, Output, State in an Dash app from dash.dependencies to dash_extensions.enrich to enable ServersideOutput? I am using DashProxy object to initiate the app and using ServersideO…

Hey everyone, Does anyone know if it is possible to ignore certain arguments when using memoization? It appears this should be possible as flask caching has an “args_to_ignore” parameter but I’m unsure where to include this parameter in the callback. Thanks in advance for any help!

Hi @Emil , In the documentation of ServerSideOutputTransform , you mentioned that it is recommended to perform scheduled cleanups outside business hours How can cleanups be scheduled? Will restarting the app cleanup the cache? Thanks for your help!

The cleanup can be scheduled using you method of choice. It could be a cron job, and scheduled background task in Python, a task scheduled by Windows scheduler. The best choice depends on you infrastructure setup.

Sorry, can I clarify what does a cleanup entail? Deleting the files cached in the file system? How would something like that work when deployed to something like Heroku? I apologize for these questions as I’m pretty new to the idea of caching. Thanks!

If you are using a file system store, then yes it would be deleting files. On Heroku, the file system is ephemeral, so I am not sure if manual cleaning is needed at all.
