A New Efficient Memory Index

In the aerospace thermal test requires high real-time analysis of big data, the data is too big so it can´t store all the collected data and index data on the memory. In order to solve the above problem proposing a memory data index, by using this index it can achieve partial store index in memory, this index uses page mechanism, every page has an unique page key, every page will maintain a certain number of index items, pages store in memory and disk, using the page key it can quickly retrieve the page stored in the disk, using the index data in the page it can quickly retrieve the collected data, there will be a certain number of pages stored in the memory, experimental results show that this method can achieve high real-time read and write performance, and consume little memory space.
