Once this is done, we can update https://confluence.lsstcorp.org/display/DM/DM+Third+Party+Software and remove dependency between Qserv and numpy.

Jacek Becla,

Ok, above documentation updated.

Hi Daniel Wang [X],

I removed some code from core/ in this ticket so I would like you to review it.
It's very small, it only removes some files.

Thanks,

Fabrice

This looks mostly fine, but... we are removing functionality.

plotChunksCopies.tcl, while dependent on output from obsolete code, is still the only way we have of visualizing the chunk layout. I recommend we keep it and plan on some small work to port it for the current infrastructure.

rebalance.py provides a chunk-to-node mapping. It should work fine on the new partitioner's output. It depends on loader.py. Do we have a replacement for it? We might borrow code from this and the old loader in building the multi-node loader, so I think we should wait until the multi-node loader is done before removing this (and loader.py, even though we won't be using loader.py to load anymore).

So, I suggest keeping plotChunksCopies, rebalance, and loader. Maybe put a note in loader.py to say that it is only being kept in support of rebalance, and both should go away when a multi-node loader lands.

I Daniel,

I put the tree files in core/examples/obsolete, added core/examples/obsolete/README.txt and created a new ticket DM-1902 for plotChunkCopies.tcl port.

Thanks.
