Internal error processing get in get after insert ttl

Hello, I tried to use Column.Ttl property but I was not successful. My simple test: 1) insert column with ttl = 3 2) get column - all is ok 3) wait for 2 seconds 4) get column - all is ok 5) wait again for 2 seconds (so column should disappear) 6) get column - I got Thrift.TApplicationException

Re: column expiration and rows in 0.7

Thanks.. but, in 0.7 every CF has its own GCgraceSeconds which is gc_grace_seconds, and I am setting gc_grace_seconds to 5 hours and the columns ttl to 4 hours, this means that after 5 hours the columns should be removed, and the keys are removed too, right?, however, I still see the keys

Re: column expiration and rows in 0.7

A few things: 1- in your case, the expiring columns are gc-able 5 hours after the column expires. So roughly 9 hours after the column insertion, not 5. 2- columns are not necessarily removed after gc_grace_seconds elapses exactly. They get removed by the first *major* compaction

Throughput performance problem

When inserting rows to Cassandra, we have noticed an odd performance behavior. When we insert rows with increasing row keys (0,1,2,...) we get a throughput that is 10% higher than when we insert rows with random row keys (in the range of 0 to 1'000'000). This is strange because we use the

Hi I was using 'access_logs' as column family name changed it to Accesslogs and it worked. May be cassandra doesn't like underscores and small letters. Regards Vineet Daniel Cell : +918106217121 Websites : Blog http://vinetedaniel.blogspot.com |

Re: Internal error processing get in get after insert ttl

Unfortunately, I'm running Cassandra on Windows platform and the logging doesn't work; I'm not able to configure them properly respectively. I always get log4j:WARN No appenders could be found for logger (org.apache.cassandra.utils.CLibrary). after Cassandra starts. I tried to copy

Oups, that would be a bug. Would you mind grabbing the patch attached to https://issues.apache.org/jira/browse/CASSANDRA-1539 and check that is does fix the problem ? -- Sylvain On Thu, Sep 23, 2010 at 1:28 PM, Michal Augustýn augustyn.mic...@gmail.com wrote: Ah, I didn't know that, thank you!

NullPointerException in TCP Selector Manager [Cassandra 0.5.1]

Hello, I've been working with Cassandra for some time and get this error intermittently: ERROR [TCP Selector Manager] 2010-09-23 08:42:18,138 service.CassandraDaemon Fatal exception in thread Thread[TCP Selector Manager,5,main] java.lang.NullPointerException at

Re: Thrift gen problem with cassandra.thrift

I finally grabbed Cassandra off the trunk to make things work so I guess it is 0.7. If I start the same server and connect to it, should things work? I am happy using pycassa or telephus but I had Thrift installed for things beyond Cassandra (for example for Hypertable) and I was hoping that

Yes, that is a problem with 0.5.1. Unfortunately we are not planning any more releases to 0.5. On Thu, Sep 23, 2010 at 1:18 PM, Adam Holmberg adam.holmberg.l...@gmail.com wrote: Hello, I've been working with Cassandra for some time and get this error intermittently: ERROR [TCP Selector
