在BigTable/GFS和Casses术语中,SSTable的定义是什么?
职业病理学表(从 go角bor出)是主要/价值乳制品的档案,由钥匙分类。
“一种可变的地图,从钥匙到价值,在关键和价值都是任意的外壳。 提供业务是为了研究与特定钥匙相关的价值,并在特定的关键范围内对所有关键/价值配对。 在内部,每个SSTable公司都有一系列的区块(通常每个区块面积为64KB,但这是可以想象的)。 用于确定区块的整块指数(在SSTable公司结束时储存);该指数在SSTable开立时被装入记忆中。 可以通过单一磁盘进行盘点:我们首先通过在圆形指数中进行双轨搜索,然后从磁盘中读出适当的栏。 单是,可以完全将SSTable打成记忆,使我们能够在不触及磁盘的情况下进行搜索和扫描。
SSTable (engl. Sorted Strings Table) is a file of key/value string pairs, sorted by keys.
An SSTable provides a persistent,ordered immutable map from keys to values, where both keys and values are arbitrary byte strings.
Internally, each SSTable contains a sequence of blocks (typically
each block is 64KB in size, but this is configurable).
表格以SSTables的形式储存。
可变现(直接标明给全球商品安全局)是基于关键价值的可变储存。 它储存数据库,每组64KB。
定义:
SSTable means sorted string table" based on key- Value pair. 在Casses,SSTables是不可变的,由钥匙分类。
