报告内容摘要：

In this article, the author presents  a summary of the key techniques, namely bitmap compression, encoding and  binning. The advances in these techniques have led to a search tool that can  answer structured (SQL) queries orders of magnitude faster than popular  database systems.FastBit is designed to accelerate user's data selection  tasks without imposing undue requirements.

报告内容摘要：

A lightweght index called the  CR-index(Continuous Range Iindex) base on log-structured storage small enough  to reside in main memory and fast to construct exploit observational data’s  continuity avoid indexing each item achieve high write throughput in  write-heavy applications
