[DAS] 1 Mb detailed view limit

[Simon Hearsey]

Dear Tony et al,
I should have been more clear, I am running the Ensembl server locally as well as a local DAS server.  I have tried, unfruitfully, to find where the configuration is that sets the limit to 1Mb.  Can you point me in the direction of the code?
Thanks,
Simon

This is an internal limit imposed for performance reasons at the Ensembl server
end. We could allow users to select arbitrary genome region but it could cripple
the server if somebody wanted to look at every feature on chromosome N for
instance -  of course they would get bored waiting for the answer amd go off and
do the same query on a different chromosome....

...meanwhile back at the ranch we are watching servers die painful deaths.

We could review the contigview limit but in all honesty I suspect the mimit is
never going to be ideal for everybody and we have to draw a balance between the
needs of specialised uers and general performance for the masses.

Of course, the solution to this is for you to have a local Ensembl installation
where you can change the defaults to whatever you need.

regards

Tony
