Re: Transaction failed because of timeout, retry failed because of the first try actually succeeded.

I had this problem, and it was caused by my retry policy. For reasons I don’t remember (but is documented in a C* Jira ticket), when onWriteTimeout() is called, you cannot call RetryDecision.retry(cl), as it will be a CL that is incompatible with LWT. After the fix (2.1.?), you can pass null,

Hi everyone, I recently encountered a problem wrt light weight transaction. My query is to insert a row to a table if the row doesn't exist. It goes like this: Insert Into mytable (key, col1, col2) Value("key1", 1, 2) If Not Exist My case is the driver somehow gets time out from waiting for

Re: Motivation for a DHT ring

With fault tolerance and reliability, it also gives a faster lookup mechanism across various nodes in a cluster. Amazon's dynamo paper might be a better read to understand the reasoning behind a DHT based system: http://www.allthingsdistributed.com/files/amazon-dynamo-sosp2007.pdf On Wed, Jun 29,

RE: Exception in logs using LCS .

Hi Paulo, Thanks for the reply. Running scrub every time the exception occurs is not a possible solution for us. We don’t have a log patrolling system in place that verify the log on regular basis. I have some queries based on your reply: 1. You mentioned race condition. Can you please

Hi, Could it be garbage collection occurring on nodes that are more heavily loaded? Cheers, Jens Den sön 26 juni 2016 05:22Mike Heffner skrev: > One thing to add, if we do a rolling restart of the ring the timeouts > disappear entirely for several hours and performance

Re: Motivation for a DHT ring

Some reasons I can come up with: - it would be hard to have tunable read/consistencies/replicas when interfacing with a file system. - data locality support would require strong coupling to the distributed file system interface (if at all possible given that certain sstables should live on the
