And not just the GPL, but the AGPL. That one caught me by surprise. Does this mean there is going to be a MySQL-style dual-licensing situation in the future? (or is this already the case?)
PipelineDB is actually licensed under the GPLv3. We accidentally updated our files with the AGPL earlier today by mistake but have since rectified that. Apologies for the mixup!
As much as thank you comments are downvoted here I'll still say: Thank you! Same goes to everyone else who avoids hasseling developers everywhere with AGPL.
