    • Techniques are disclosed for selecting a delete-safe compression method for a plurality of delta encoded data values (e.g., delta encoded integers or deltas). For example, a computer-implemented method for selecting an optimal delete-safe compression algorithm from among two or more compression algorithms for use on a plurality of delta encoded data values includes the following steps. The maximum number of data values eliminated by each of the two or more compression algorithms is computed. For the plurality of delta encoded data values to be compressed, the minimum size of the plurality of delta encoded data values before compression thereof is computed. A delete-safe threshold value is computed based on the minimum size of the plurality of delta encoded data values. Then, the compression algorithm is selected from the two or more compression algorithms that achieves the delete-safe threshold value.
    • 公开了用于为多个增量编码的数据值(例如,增量编码的整数或三角形)选择删除安全的压缩方法的技术。 例如,用于从用于多个增量编码数据值的两个或更多个压缩算法中选择最佳删除安全压缩算法的计算机实现的方法包括以下步骤。 计算由两个或更多个压缩算法中的每一个消除的数据值的最大数目。 对于要压缩的多个delta编码数据值,计算其压缩之前的多个Δ编码数据值的最小大小。 基于多个增量编码数据值的最小大小来计算删除安全阈值。 然后,从实现删除安全​​阈值的两个或更多个压缩算法中选择压缩算法。

    • Techniques are disclosed for encoding a variable length structure such that it facilitates forward and reverse scans of a list of such structures as needed. While the techniques are applicable to a wide variety of applications, they are particularly well-suited for use with structures such as those found in compressed database indexes. For example, a computer-implemented method for processing one or more variable length data structures includes the following steps. Each variable length data structure is obtained. Each variable length structure comprises one or more data block. A variable length encoding process is applied to the one or more blocks of each variable length data structure which comprises setting a continuation data value in each block to a first value or a second value, wherein the setting of the continuation data values enables bi-directional scanning of each variable length structure.
    • 公开了用于编码可变长度结构的技术,使得其有助于正向和反向扫描所需的这种结构的列表。 虽然这些技术适用于各种各样的应用,但它们特别适用于诸如在压缩数据库索引中发现的结构。 例如,用于处理一个或多个可变长度数据结构的计算机实现的方法包括以下步骤。 获得每个可变长度数据结构。 每个可变长度结构包括一个或多个数据块。 可变长度编码处理被应用于每个可变长度数据结构的一个或多个块,其包括将每个块中的连续数据值设置为第一值或第二值,其中,连续数据值的设置允许双向 扫描每个可变长度结构。
