Loading Binary files in Cassandra DB
Hello Team, I am going to use Cassandra DB in our existing project as its suiting my requirement. I have binary files generated from our application every one minutes and have to store them in DB. I have a table which is having 100+ column on which customer is going to use only 10 column for searching data. I would like to know if there are any loader supported for loading binary files into DB or please guide me how to write it Thanks Regards Akshay Ghanshyam Ballarpure Tata Consultancy Services Cell:- 9985084075 Mailto: akshay.ballarp...@tcs.com Website: http://www.tcs.com Experience certainty.

Write Inconsistency to update a row
I have two Cassandra 2.0.5 servers running with some datas inserted, where each row have one empty column. When the client send a lot of update commands to fill this column in each row, some lines update their content, but some lines remain with the empty column. Using one server, this never happens! Any suggestions? Tks. -- Atenciosamente, Sávio S.

Re: Write Inconsistency to update a row
This seems like a hinted handoff issue but since you use CL = ONE it should happen. Are you sure all the nodes are working at that time? You could use nodetool status to check that. I would suggest increasing the replication factor (for example 3) and use CL=ALL or QUORUM to find out what is going wrong. Regards, Panagiotis On Thu, Jul 3, 2014 at 5:11 PM, Sávio S.

Re: Triggers and their use in data indexing
This is one of the trickier areas of doing multi dc. The current recommendation is to use a separate message queue. If you'd like to see remote triggers, you could fire a JIRA. Get back to the list w/ the ticket #, I'm sure there are others who have similar needs.

Re: keyspace with hundreds of columnfamilies
thank you for the replies; I am rethinking the schema design, one possible solution is to implode one dimension and get N times less CFs. With this approach I would come up with (cql) tables with up to 100 columns; would that be a problem? Thank You, Tommaso 2014-07-02 23:43 GMT+02:00 Jack Krupansky j...@basetechnology.com: The official answer, engraved in stone tablets, and carried down from the mountain: “Although having more than dozens or hundreds of tables defined is almost certainly a Bad Idea (just as it is a design smell in a relational database), it's relatively straightforward to allow disabling the SlabAllocator.” Emphasis on “almost certainly a Bad Idea.” See: https://issues.apache.org/jira/browse/CASSANDRA-5935 “Allow disabling slab allocation” IOW, this is considered an anti-pattern, but... -- Jack Krupansky *From:* tommaso barbugli tbarbu...@gmail.com *Sent:* Wednesday, July 2, 2014 2:16 PM *To:* user@cassandra.apache.org *Subject:* Re: keyspace with hundreds of columnfamilies Hi, thank you for you replies on this; regarding the arena memory is this a fixed memory allocation or is some sort of in memory caching? I ask because I think that a substantial portion of the column families created will not be queried that frequently (and some will become inactive and stay like that really long time) Thank you, Tommaso 2014-07-02 18:35 GMT+02:00 Romain HARDOUIN romain.hardo...@urssaf.fr: Arena allocation is an improvement feature, not a limitation. It was introduced in Cassandra 1.0 in order to lower memory fragmentation (and therefore promotion failure). AFAIK It's not intended to be tweaked so it might not be a good idea to change it.

Thanks Tommaso 2014-07-02 17:21 GMT+02:00 Romain HARDOUIN romain.hardo...@urssaf.fr: The trap is that each CF will consume 1 MB of memory due to arena allocation. This might seem harmless but if you plan thousands of CF it means thousands of mega bytes... Up to 1,000 CF I think it could be doable, but not 10,000.

At this present I am running with 300 column families but I expect that to get to a couple of thousands. Is this something discouraged / unsupported (I am using Cassandra 2.0). Thanks Tommaso
