Re: Timeout Exception in get_slice

If I was rebuilding my power after spending the first thousand years of the Third Age as a shapeless evil I would cast my Eye of Fire in the direction of the filthy little multi_gets. A node can fail to respond to a query with rpc_timeout for two reasons: either the command did not run or the

Hi, Can someone give some more details about the CASSANDRA-4116 bug fixed in this release? Could this cause resurrection of deleted data for example? https://issues.apache.org/jira/browse/CASSANDRA-4116 / Jonas On 2012-05-08 11:04 , Sylvain Lebresne wrote: > The Cassandra team is pleased to an

Re: count after truncate NOT zero

enforcing ordering

Hi, I'm wondering if there is a common 'pattern' to address a scenario we will have to deal with. We will be storing a set of Column/Value pairs per Key where the Column/Values are read from a set of files that we download regularly. We need the loading to be resilient and we can receive correcti

There is no support in the cli for using a socks proxy. You would need to add it. Take a look in CliMain.java Cheers - Aaron Morton Freelance Developer @aaronmorton http://www.thelastpickle.com On 8/05/2012, at 10:00 AM, Shawna Qian wrote: > Hello: > > In our cassandra sett

Can you store the corrections in a separate CF? When the client reads the key, reads from the original the corrects CF at the same time. Apply the correction only on the client side. When you have confirmed the ingest has completed, run a background jobs to apply the corrections, store the up

Re: [RELEASE] Apache Cassandra 1.0.10 released

Hi Jonas, the bug that was fixed in 4116 meant that the max timestamp recorded for an sstable didn't consider any tombstones from row deletions. This meant that from some queries, some sstables were not being read when they should have been. I couldn't say categorically that this would cause the d

Maybe one of the problems is that I am reading the columns in a row and the rows themselves in batches, using the count attribute in the SliceRange and by changing the start column or the corresponding for rows with the KeyRange. According to your blog post, using start key to read for millions
