不过,如果左右两侧都是散列索引,而用户可能希望主视图是有序的。
However, if both of them are hash indexes, the user may want the main view to be ordered.
您将找到的大部分结果都是哈希索引站点——有意地连接散列值和其相应关键字的站点。
Most of the results you'll find are hash indexing sites — sites intentionally built to connect hash values and their corresponding keys.
该索引包含实际字符串的散列值,只能用于等式谓词,不能用于范围谓词。
This index contains hash values of the actual strings and can be used for equality predicates only, not for range predicates.
访问控制列表(acl)是具有所有者和索引列表或散列的对象,如图2所示。
Access control lists (ACLs) are objects with an owner and an indexed list, or hash, as illustrated in Figure 2.
LinkedIn在其Hadoop管道上构建了一个索引结构:这会产生几个TB的查找结构,该结构完美地使用了散列(每个键只需要2.5个位)。
LinkedIn builds an index structure in their Hadoop pipeline - this produces a multi-TB lookup structure that USES perfect hashing (requiring only 2.5 bits per key).
因此,Cell对象通过Row对象中的列索引进行散列化。
Thus, the Cell objects are being hashed with the column index in the Row object.
操作数据库是为已知的任务和负载设计的,如使用主关键字索引和散列,检索特定的记录,和优化“罐装的”查询。
An operational database is designed and tuned from known tasks and workloads, such as indexing and hashing using primary keys, searching for particular records, and optimizing "canned" queries.
当哈希冲突发生时,系统不会储存新数据,因为它看到它的散列人数已经存在于索引…这就是所谓的假阳性,并可能造成数据丢失。
When a hash collision occurs, the system won't store the new data because it sees that its hash number already exists in the index... This is called a false positive, and can result in data loss.
