I had one, but later on I found out that I don't necessarily use flush to
achieve that so it's not really a valid use case that definitely need
flush...

I think Apache Solr could explore leveraging the returned sequence number
for its transaction logs.

Actually there are some interesting use cases for sequence numbers:
They enable the caller to know the effective order of operations

Hi folks,
I just realized that while "commit" returns the sequence number which
represents the latest event that committed in the index, "flush" still
returns nothing. Since they're essentially the same except fsync I wonder
whether there's any specific reason to not do so?
