Hi, I've tried to upgrade my Elephantdb shards from 0.2.0 to 0.4.4. I figured the fastest way to do this is to use the old shards from 0.2.0 and create something that is compatible with the latest versions. Reading from Cascalog with 0.4.4 seems to work for old shards and my "upgraded" shards, but loading them into the server isn't working. I get nil values for known keys. I am starting to doubt what I want is possible, but someone might be able to see what is missing in my approach:
Another option would be to write data from the old code to intermediate seqfiles, that will be read by new code, that writes them to upgraded shards. However I think it would be more convenient if the old elephantdb-cascalog was able to write to the new format.
Any ideas?
Thanks,
Jeroen
