Ye Liang commented on CASSANDRA-12767: -------------------------------------- Thank you very much,I specify a server-side timestamp generator to solve this problem. I notice that when i use a client-side timestamp generator,the cassandra driver still attach a server-side timestamp to my insert request(with ifnotexist),i want to know when will this timestamp be replaced to a server-side timestamp.I think it will be replaced in cassandra server side,if true,can you tell me the source code segment about this in Cassandra2.1.15 source code? > Cassandra Java Driver 3.1.0 Client-Side timestamp generation issue > ------------------------------------------------------------------ > > Key: CASSANDRA-12767 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12767 > Project: Cassandra > Issue Type: Bug > Environment: Cassandra 2.1.15 > Cassandra Java Driver 3.1.0 > Reporter: Ye Liang > Priority: Minor > > I use cassandra driver java to do some insert operation.I notice that > Cassandra Java Driver use client-side timestamp as default. > I make my client server one hour ahead than my cassandra server,then i insert > some record to an exist table and use sstable2json tool to check my record ' > s timestamp. > i find out that if i insert a record with ifnotexist,the record's timestamp > used server-side timestamp,otherwise it use client-side timestamp. > I think this is a very strange result. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
