Sets the serial consistency level for the query.
The serial consistency level is only used by conditional updates (so INSERT, UPDATE
and DELETE with an IF condition). For those, the serial consistency level defines
the consistency level of the serial phase (or "paxos" phase) while the
normal consistency level defines the consistency for the "learn" phase, i.e. what
type of reads will be guaranteed to see the update right away. For instance, if
a conditional write has a regular consistency of QUORUM (and is successful), then a
QUORUM read is guaranteed to see that write. But if the regular consistency of that
write is ANY, then only a read with a consistency of SERIAL is guaranteed to see it
(even a read with consistency ALL is not guaranteed to be enough).
Cassandra (in Cassandra.dll) Version: 3.13.0
Type: CassandraConsistencyLevel Can be set only to ConsistencyLevel.Serial or
ConsistencyLevel.LocalSerial. Setting it to ConsistencyLevel.Serial guarantees full
linearizability while ConsistencyLevel.LocalSerial guarantees it only in the local datacenter.
