key-value

Redis是一个key-value存储系统，和Memccached类似，支持存储的value类型相对更多，很大程度上补偿memcached这类key-value存储的不足 他提供了Java，c/c++，c#，PHP,JavaScript，Pert，Object-c，Python，Erlang等客户端 Redis支持主从同步 redis的官网地址，Redis.io，（域名后缀io属于国家级） 目前，Vmware在赞助者redis项目的开发和维护 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　自我总结 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　---------致自己

I want to create a key-value pairs in an array within a foreach. Here is what I have so far: function createOfferUrlArray($Offer) { $offerArray = array(); foreach ($Offer as $key => $value) { $keyval = array($key => $value[4] ); array_push($offerArray,$keyval); } return $offerArray; } If I declare the array within the foreach, it will overwrites it on each iteration, but defining it outside the foreach doesn't work either and causes triplets: array[0] => key => value array[1] => key => value How do I make it so I only get key-value pairs like this? key => value key => value Something like this

在使用handsontable的时候，本身的下拉列表无法满足业务需求，需要使用key-value类型的dropdown. 找了半天终于找到了一个可以满足需求的 参考方案 此方案完美的解决了我的问题。 但是使用过程中需要注意两点 1.此插件是基于chosen.jquery.js的一个jquery插件，所以使用的过程中记得引入chosen.jquery.js 与jquery.js 2.由于handsontable的版本跟新，有些api不能使用了 customDropdownRenderer 方法中的 Handsontable.TextCell.renderer需要改成Handsontable.renderers.TextRenderer 完整案例请参考 文章来源: Handsontable Dropdown with key-value pair

$lang = array( 'thank you'=>'You are welcome', 'thanks'=>'You are welcome', 'thank ya'=>'You are welcome' ); As you can see this is going to get tiresome writing multiple keys for the same value is there any way I can do. $lang['thanks']=>$lang['thank ya']=>$lang['thank you'] Just trying to save myself some time here from rewriting a hundred times PHP class function: function fetch_key($key, $l,$bool){ $dynamic = new l18n; if($bool == true or is_null($bool)){ return addslashes( $dynamic->convert($key,$l) ); }else{ return $dynamic->convert($key,$l); } } EX $lang = array( 'thank you'=>'You are

We are working on a SSD-backed key-value solution with the following properties: Throughput: 10000 TPS; 50/50 puts/gets; Latency: 1ms average, 99.9th percentile 10ms Data volume: ~1 billion values, ~150 bytes each; 64-bit keys; random access, 20% of data fits RAM We tried KyotoCabinet, LevelDB, and RethinkDB on commodity SSDs, with different Linux IO schedulers, ext3/xfs file systems; made a number of tests using Rebench ; and found that in all cases: Read-only throughput/latency are very good Write/update-only throughout is moderate, but there are many high-latency outliers Mixed read/write

I'm learning Swift lang and one of the things that would be great to hear others input about is "How you handle models from JSON responses"? For example - I have User.swift model: class User: NSObject { var user_token:String? var email:String? } and also I would like to use KeyValueObjectMapping as I do in Obj-C projects. Unfortunately this doesn't work here: let parser = DCKeyValueObjectMapping.mapperForClass(User) let user = parser.parseDictionary(data.objectForKey("user") as NSDictionary) as User println(user.user_token) // returns nil How do you create your models in Swift? I recommend

I was wondering if there was a lightweight, embeddable, key/value database out there. Something like a lightweight Couchdb (RESTful, key/value, etc) where you just send it the key and it responds with appropriate values. Thanks! Evan On the Related Projects page of the CouchDB wiki, under "Alternatives" they mention some similar projects: Feather DB * CouchDB clone in java. StrokeDB * A CouchDB-like database written in Ruby to make embedding into Ruby apps easier. mongoDB A high-performance, open source, schema-free document-oriented database. And of course Tokyo Cabinet which has already been

All of the examples of Kafka | producers show the ProducerRecord 's key/value pair as not only being the same type (all examples show <String,String> ), but the same value . For example: producer.send(new ProducerRecord<String, String>("someTopic", Integer.toString(i), Integer.toString(i))); But in the Kafka docs, I can't seem to find where the key/value concept (and its underlying purpose/utility) is explained. In traditional messaging (ActiveMQ, RabbitMQ, etc.) I've always fired a message at a particular topic/queue/exchange. But Kafka is the first broker that seems to require key/value
