Support for using bokeh protocol in the notebook including binary transfer #1894
The bokeh/bokeh#6945 PR adds support for sending bokeh events in the notebook using the regular bokeh protocol. This means we can now take advantage of binary transfer for arrays providing a ~5x speedup, which is particularly noticeable for images. Additionally this will allow us to dynamically add new glyphs to a plot, which means a DynamicMap will be able to return varying numbers of layers with a bit of work.
For now I've left in support for the old way of generating JSON patches and moved some small deprecated bokeh functions into holoviews, as it's not quite clear to me yet whether we can use the protocol for statically embedded data.
That sounds really helpful, and is something that will greatly simplify a lot of user code. What was the change that made that possible?
