[jira] [Issue Comment Deleted] (CASSANDRA-9283) Deprecate unlogged
batches
[ https://issues.apache.org/jira/browse/CASSANDRA-9283?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andriy Kolyadenko updated CASSANDRA-9283:
-----------------------------------------
Comment: was deleted
(was: 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.
