Why did you choose java for the operator implementation when everybody seems to use the go client (probably for greater functionalities) ? 2018-05-23 15:39 GMT+02:00 Ben Bromhead : > You can get a good way with StatefulSets, but as Tom mentioned there are > still some

Re: Pluggable throttling of read and write queries

Aren't you using mesos Cassandra framework to manage your multiple clusters ? (Seen a presentation in cass summit) What's wrong with your current mesos approach ? I am also thinking it's better to split a large cluster into smallers except if you also manage client layer that query cass and you

Hi all, Is there any way to trace user activity at the server level to see which user is accessing which data ? Do you thin it would be simple to implement ? Tx

Re: [External] Re: Cassandra ad hoc search options

The problem with adhoc queries on casssandra (with spark or not) is the partition model of cassandra that needs to be respected to avoid full scan queries (the link you mentioned explains all of them). With FiloDB, which works on cassandra, you can pushdown predicates of the partition key and

Re: Cassandra data modeling for a social network

Or use graphframes (Spark) over cassandra to store separately a graph of users and followers and next a table of tweet. You will be able to join data between those 2 structures using spark. 2016-05-31 14:27 GMT+02:00 : > Hello, > > >* First, Is this data modeling

cassandra disks cache on SSD

I am looking for way to optimize large reads. I have seen using SSD is a good option but out of budget, so I am looking for a way to use some kind of tiering with few SSD caching hot data from HDD. I have identified two solutions and would like to get opinions from you and if you have any
