问题 I am working on a project in which I need to use Cassandra Database . I have a sample program that will populate data into Cassandra database . I am using Pelops client for that. So now I am thinking of making a Singleton class for Cassandra database that will make a connection to Cassandra database and then I be using that instance from Singelton class into my CassandraDAO to insert into Cassandra database and retrieve the data from Cassandra database as well. Below is my Singleton class

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I have recently started working with Cassandra Database. Now I am in the process of evaluating which Cassandra client we should go forward with. I have seen various post on stackoverflow about which client to use for Cassandra but none has very definitive answer. My team has asked me to do some research on this

问题 I've written a "census" program to iterate through all the rows in a Column Family and within each row count the columns, recording the max value and row key. I've been spending more time with the Hector client but have written a Pelops client as well to test. The basic flow is to use use a RangeSlicesQuery to iterate through the rows, and then at each row, use a SliceQuery to iterate through and collect the stats. Works similar in Pelops, just different APIs. Downside is having to do the

I have seen various post on stackoverflow about which client to use for Cassandra but none has very definitive answer. My team has asked me to do some research on this and come up with certain pros and cons for each Cassandra Client API’s in Java. As I mentioned, I recently got involved with Cassandra so not have that much idea why certain people choose Pelops client and why certain people go with Astyanax and some other clients. I know brief things
