> The following are reasons of refactoring.
> # A update-heavy application, for example, loader, creates many BufferedMutator for batch
updates. But these BufferedMutators can’t share a large threadpool because the shutdown()
method will be called when closing any BufferedMutator. This patch adds a flag into BufferedMutatorParams
for preventing calling the shutdown() method in BufferedMutatorImpl#close
> # The AsyncProcess has the powerful traffic control, but the control is against the single
table currently. We should allow alternate traffic control implementation for advanced user
who want more control.
> All suggestions are welcome.
