btw, I am considering using it to speedup (parallel) online queries over
large dataset. Is pig suitable for this, or just suitable for offline large
data analysis? Will it be a better choice than distributed(parallel)
database in terms of scalability and latency?
I really like the pig's programming interface. So I want to try to use it
instead of using parallel database.
Thanks!
cheers,
W.
