Persistent Filesystem

100%

Large data apps deploy smoother and run faster. Upload 25GB flat files to your app and Dash Enterprise 5.0 will ensure your data remains accessible — after deployment and in the Data App Workspace IDE — without external data storage services.

Workspaces.gif

Dash Enterprise 5.0 enables you to upload, update, and cache up to 25GB or 500M rows of data directly in your browser. (That's 500x the amount that you could store in excel!) Drag-and-drop large Parquet, Arrow, or CSV files without Git or third-party storage services.

Screen Shot 2022-10-14 at 2.56.58 PM.png

Time well spent is time working on your data, not building pipelines or waiting for things to load. Dash Enterprise's Persistent Filesystem stores large datasets between your Workspace IDE, your deployed app, and background tasks, enabling:

Faster access to datasets that are too big to store in Git or that would require third-party storage

Cache files that can be persisted across deploys

Dynamic data updates through periodic background processes read by the Dash app

Manually updated data updates in your workspace without redeploying your app

Vaex (1).gif

Visualizing 10s or 100s of millions of rows of data? Dash Enterprise 5.0 supports high-performance, out-of-memory data processing.

The Persistent Filesystem supports large Parquet, Arrow, and HDF5 file formats better than standard containerized deployment systems. Deployed Dash apps can visualize 120 million rows of data in less than four seconds and 3 lines of code.

It is often faster to store a copy of your data close to your app rather than download it on-the-fly.

Dash Enterprise’s Persistent Filesystem allows you to upload, read, update and cache datasets up to 25GB per app without introducing network costs or delays while keeping these large files out of Git repositories.

With Persistent Filesystem, simplify your data science workflow and avoid network delays. Large data can be uploaded, updated, and cached in Dash Enterprise.
