Best way to deploy bokeh app with big dataset

Community Support
1

Hi all

Currently i have a project using Bokeh, i generate html file then copy div and script to my html file then host the standalone html with my server.

But for big data like millions or so rows the html file will be too big and it will be slow to render so my question is which is the best way to deploy the app?

My project relate mostly to data table and some basic chart.

Thanks

Hi,

You might want to look at Holoviews, which can generate Bokeh output that also integrates tightly with Datashader (which can handle very large datasets, e.g. billions of points)
  
  Working with large data using datashader — HoloViews v1.18.1

Thanks,

Bryan

Hi Bryan

Can Holoviews work with JS callback?

Thanks

Hi,

Holoviews can produce Bokeh output which is the same as any output from Bokeh's own APIs and has all the same capabilities.

Thanks,

Bryan

On SO I suggested to use ColumnDataSource to achieve interactivity in the plot and got this comment:

Hi Tony, thanks for your answer - The problem I have is that Holoviews does not accept the ColumnDataSource as underlying data model and therefore I cannot make use of the source.change.emit() to let the plot update itself – dmeu 19 hours ago

I don’t know Holoviews, can someone confirm if this is true?

Hi,

You should pose this question to the Holoviews devs directly. One place they hang out is on Gitter:

Thanks,
