Ye Liang updated CASSANDRA-12767:
---------------------------------
Description:
When I use Cassandra Java Driver to connect a C* cluster with a Protocol
Version 3,such as :
Builder builder = Cluster.builder().withProtocolVersion(ProtocolVersion.V3);
I insert some record to an exist table using ifnotexist,for example:
QueryBuilder.insertInto(xxx).ifNotExists();
Then,i will delete the record normally.
i do the two step over and over again
I find something strange to me :
insert and delete operation are always success(no exception and the response
looks ok).but before i delete the record,i use select statement to query my
record.when i insert the record for the first time i can always query my
record.but after that i seldom query my record successfully between insert and
delete.
I just use a single node cassandra cluster to exclude the effect of data
consistency.And when i use a Protocol Version 2,it works well,everytime i query
my record between insert and delete works

addition:
Although i can not query my records,i can find out which sstables my record is
in using nodetool getsstables.
when i enable the tracing in cqlsh,the result like that :
a | b | c |
---+---+---
1 | 2 | 4 |
