You can find a small script below. This doesn’ t produce any errors though. The glyphs I am working with are wedges rather than circles.

could you explain what is happening in background tornado web socket?
I don’t really have any idea what information you are asking for, specifically.

I am trying to update a column data source with len 40000 information having 7 columns. This causes web connection to close. The workaround I found and as earlier suggested to me was to send the data in chunks. That works okay but is there an another way as this requires to set up threads and updating the doc? I found th following issue
which says that websocket_max_message_size is allowed to be overwritten. But when I do so and increase the default 10 mib to 20 mib, I run into another problem of memory leak and besides the connection is closed anyway just because I am tyring to send large amount of data. Is there a solution to this and could you explain what is happening in background tornado web socket?
