Tania S Engel updated CASSANDRA-10876:
--------------------------------------
Comment: was deleted
(was: In 3.11.1 we still see these warnings even when we are inserting into
multiple tables with the same partition key. The comment above from Patrick
seems to indicate a partition key is for one keyspace.table. But I thought a
partition key was a value that hashed to the same value. Is it still a burden
on the coordinator worthy of a warning if we do a batch insert to 4 tables with
the same partition key ({color:#333333}Day{color})? For example if we do a
batch insert into these 2 tables, is that considered a single partition insert
and if so why is there a warning?
CREATE TABLE Log_User (Day timestamp, LogTime timeuuid,
{color:#333333}UserID{color} int) PRIMARY KEY ({color:#333333}Day {color},
UserID, LogTime)
CREATE TABLE Log_Event( Day timestamp, LogTime timeuuid, EventID int)
{color:#333333}PRIMARY KEY ({color}{color:#333333}Day {color}{color:#333333},
EventID , LogTime){color})
> Alter behavior of batch WARN and fail on single partition batches

> In an attempt to give operator insight into potentially harmful batch usage,
> Jiras were created to log WARN or fail on certain batch sizes. This ignores
> the single partition batch, which doesn't create the same issues as a
> multi-partition batch.
> The proposal is to ignore size on single partition batch statements.
