When the load balancer can use round robin algorithm to distribute the incoming request evenly to the nodes why do we need to use the consistent hashing to distribute the load? What are the best sc...

I am trying to understand how consistent hashing works. This is the article which I am trying to follow but not able to follow, to start with my questions are: I understand, servers are mapped in...

My understanding of consistent hashing is that you take a key space, hash the key and then mod by say 360, and place the values in a ring. Then you equally space nodes on that ring. You pick the no...

I'm using redis cluster 3.0.1. I think redis cluster use consistent hashing. The hash slots are similar to virtual nodes in consistent hashing. Cassandra's data distribution is almost the same as ...

I am trying to understand how different Load Balancing strategy works. One way is to use consistent hashing algorithm where we divide the entire space into multiple virtual nodes and each physical ...

It is common to require ordering in same partition of given Kafka topic. That is, messages with same key should go to same partition. Now, if I want to add new partition in a running topic, how to ...

This is perhaps specific to an implementation that I'm looking at (node-hashring), but what is the difference between virtual nodes (vnodes) and replicas in a consistent hash ring? The original Ak...

I'm looking into using a consistent hash algorithm in some java code I'm writing. The guava Hashing library has a consistentHash(HashCode, int) method, but the documentation is rather lacking. My i...

I have a producer that I want to distribute work consistently across consumers by consistent hashing. For example, with consumer nodes X and Y, tasks A, B, C should always go to consumer X, and D, ...

Story I have 3 memcached servers running where I shutdown the one or the other to investigate how PHP-memcached behaves upon a server not beeing reachable. I have defined 4 servers in PHP, 1 to sim...

We have an app that the Python module will write data to redis shards and the Java module will read data from redis shards, so I need to implement the exact same consistent hashing algorithm for Ja...

I'm not talking about distributed key/value systems, such as typically used with memcached, which use consistent hashing to make adding/removing nodes a relatively cheap procedure. I'm talking abo...

There is a lot available on the Net about consistent hashing, and implementations in several languages available. The Wikipedia entry for the topic references another algorithm with the same goals:...

I have been trying for the whole day to understand and code for Memcache with PHP but I am getting confused at few points. I have gone through many articles and almost every SO questions related th...

I am using spymemcached & HashAlgorithm.KETAMA_HASH to connect to a pool of memcached of 5 nodes. My understanding is when we use a consistent hashing algorithm like, when a node is down, we d...

Trying to horizontally scale out the Redis instance working as the task server for Python-RQ. As far as I know, the best way to do this would be to add sharding logic (most likely using Consistent...

Assume I have two memcached nodes (node A, B) at the beginning, and when I add a new node C, a portion of the keys are remapped and thanks to consistent hashing only some of them. Let's assume a v...

Basically, I would want to implement the following algorithms and analyze how the system built using these algorithms behave under different conditions. Gossip protocol Multiple paxos Consistent ...

I am trying to figure out if I am on the right track. I am building a (real-time) statistics/analytics service and I use redis to store some sets and hashes. Now let's assume I have some success a...

I'm having a problem with MessageDigest returning different hash values on different computers. One computer is running 32-bit Java on Windows Vista and the other is running 64-bit Java on Mac OS....
