问题 Is Terracotta a distributed cache? 回答1: Although you don't specify which product you are talking about, I'm going to assume you mean the open source platform itself. The short answer is no, but it can be used to write a distributed cache, and it has been in one of their own products (Ehcache). You can see an overview of what the core engine is about here (it seems that they are hiding the information on their open source platform behind a registration wall now). It is a clustering engine that

问题 Does anybody have a working example of how to configure a cluster of nodes to share an index using the infinispan directory provider? All the documentation on Infinispan (the documentation is seriously lacking btw) implies that it should be as easy as having some properties set but no matter how I try I cannot get it to work. The nodes in the cluster find eachother fine and I can do get operations on one node and get object that were put on another. But as soon as I do queries (use the index)

One of the decisions I need to make is what caching framework to use in my system. With so many to choose from, I am currently investigating redis, ehcache and memcached. Can anyone point to performance benchmarks of these three particular frameworks? Also an overview of their features - I am particularly

问题 I have a task to build a prototype for a massively scalable distributed shared memory (DSM) app. The prototype would only serve as a proof-of-concept, but I want to spend my time most effectively by picking the components which would be used in the real solution later on. The aim of this solution is to take data input from an external source, churn it and make the result available for a number of frontends. Those "frontends" would just take the data from the cache and serve it without extra

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 compiled trafficserver-4.1.2 on two openvz containers running on Debian Squeeze, located on two different physical root nodes. Everything including caching is working fine, except for the clustering. I added the same name to the two nodes, as traffic_line -s proxy.config.proxy_name -v fetest Configured to run

问题 I'm currently using couchbase for quick and distributed access of data. I have Community objects being stored by the keys "comm-{index}" where {index} is the key index for a given community object (i.e. comm-1 stores object 1, comm-2 stores object 2 a so on). I need to retrieve a list containing all of the Community objects, and I wonder: would it be better (faster) to do a GET of every object one by one and add it to a list, or otherwise, storing a List object identified by a key, and

问题 I want to make my understanding about hadoop distributed cache clear. I know that when we add files to distributed cache, the files get loaded to the disk of every node in the cluster. So how do the data of the files get transmitted to all the nodes in the cluster. Is it through the network? If so, will it not cause a strain on the network? I have the following thoughts, are they correct? If the files are large, wont there be network congestion? If the number of nodes are large, even though

问题 I'd like to know if there is any distributed cache systems like memcached, velocity or sharedcache that allows me to tag content with more than just it's name, or that can relate items to eachother, so if i invalidate the cache for one item it also invalidates the related items too. eg. if i have two pages that reference the same data and that data changes, i'd like the cache for the two referencing pages to invalidate. or is this an addition to one of those projects begging to be developed?

问题 I try to find how to implement distributed caching for applications. Ehcache already used for caching in my project, that's why I search how to solve this issue using it. But, unfortunately, it seems, that Terracotta Enterprise Suite is needed for this and it is commercial. Isn't it? Is there another solution how to use Ehcache for distributed caching (RMI or anything else)? 回答1: You don't need terracotta enterprise suite to cluster you Ehcache instances. So you can use clustering with

问题 I am using infinispan to distribute the cache over multiple nodes using multicast which is working fine. Unfortunately, according to the System Admin requirements they don't want to allow multicast and they gave me a set of the possible node IP addresses. Is there a way programatically or via infinispan.xml or jgroups.xml to define the set of IP Addresses of the nodes instead of auto discovery? If not is there an alternative cache that fit the same requirement? 回答1: You need to adjust JGroups
