Subject understanding batch atomicity
Date Fri, 29 Sep 2017 15:07:53 GMT
Hi,

About BATCH, the Apache doc https://cassandra.apache.org/doc/latest/cql/dml.html?highlight=atomicity
says :

"The BATCH statement group multiple modification statements (insertions/updates and deletions)
into a single statement. It serves several purposes:
...
All updates in a BATCH belonging to a given partition key are performed in isolation"

Is "All updates" meaning equivalent to "All modifications (whatever it's sources: INSERT or
UPDATE statements)" ?

Or, is "updates" meaning partition-level isolation only for UPDATE statements into the batch
(w/o taking into isolation the INSERT other statements into the batch) ?

Thanks

Regards
Dominique
