Jon Haddad commented on CASSANDRA-10701:
----------------------------------------

There's a few references here: https://cassandra.apache.org/doc/cql3/CQL.html

Instead of:

{quote}By default, all operations in the batch are performed atomically. See 
the notes on UNLOGGED for more details.{quote}

how about:

{quote}By default, all operations in the batch are performed as LOGGED, to 
ensure all mutations eventually complete. See the notes on UNLOGGED for more 
details.{quote}

Replace:
{quote}By default, Cassandra uses a batch log to ensure all operations in a 
batch are applied atomically. {quote}
With:
{quote}By default, Cassandra uses a batch log to ensure all operations 
eventually complete. {quote}

Replace:
{quote}There is a performance penalty for batch atomicity when a batch spans 
multiple partitions. If you do not want to incur this penalty, you can tell 
Cassandra to skip the batchlog with the UNLOGGED option. If the UNLOGGED option 
is used, operations are only atomic within a single partition.{quote}
