建议阅读时间：1分钟 0.太长不看版 移除Dictionary中某个Key-Value 对不能使用removeValueForKey() 方法1: 使用API: removeValue(forKey: Int)  var someDict:[Int:String] = [1:"One", 2:"Two", 3:"Three"]  var removedValue = someDict.removeValue(forKey: 2)  ​  print( "key = 1 的值为 \(someDict[1])" )  print( "key = 2 的值为 \(someDict[2])" )  print( "key = 3 的值为 \(someDict[3])" )  ​ 方法2: 使用API: remove(at: Dictionary<Key,…

NVMCached: An NVM-based Key-Value Cache

NVMCached: An NVM-based Key-Value Cache Xingbo Wu, Fan Ni, Li Zhang, Yandong Wang, Yufei Ren, Michel Hack, Zili Shao, and Song Jiang, in Proceedings of the 7th ACM SIGOPS Asia-Pacific Workshop on Systems, 2016.

This is a short (6 page) paper that discusses the challenges of taking a memory based key-value cache (e.g., memcached) and converting it to use a non-volatile memory.  Because the authors…

SILT: A Memory-Efficient, High-Performance Key-Value Store

SILT: A Memory-Efficient, High-Performance Key-Value Store Hyeontaek Lim, Bin Fan, David G. Andersen, Michael Kaminsky, in Proceedings of the 23rd Symposium on Operating Systems Principles (SOSP ’11), October 23-26, 2011, Cascais, Portugal. In this paper, we have an interesting hybrid key-value store; part of the store is in DRAM, while the rest of it is stored in flash storage.  The authors have…

Cache Craftiness for Fast Multicore Key-Value Storage

Cache Craftiness for Fast Multicore Key-Value Storage Yandong Mao, Eddie Kohler, Robert Morris, in Proceedings of the 7th ACM european conference on Computer Systems (Eurosys ’12), pp. 183-196, Bern, Switzerland, April 10 – 13, 2012. In this work, the authors build a key-value system called MassTree.  This is an in-memory Key-Value store (I will look at several of them, in fact).  What is novel…
