Andriy Kolyadenko commented on CASSANDRA-9283:
----------------------------------------------
Hi there,
in my understanding, cross-partition unlogged batches are widely used by
community for fast hustle free bulk data import into Cassandra.
Other alternative approaches:
- CQLSSTableWriter - much harder to setup and maintain in the program logic
- individual Async writes - much slower than unlogged batch in few nodes setup
(up to 10 times slower in my observations)
- logged bacth - slower than unlogged batch - (3 times slower in my
observations)
Is it possible to undeprecate/keep unlogged batch, or develop some other simple
to use bulk insert API for fast insertion of data?
Thank you.

> Officially mark unlogged batches deprecated.
> Note that the main "good" use case for unlogged batches, of multiple updates
> in a single partition key, is "free" when done as a logged batch. So really
> unlogged batches mainly serve as a honeypot to trick new users into abusing
> them in misguided bulk loading attempts.
