Summary: | The invention discloses an HBase secondary memory index construction method based on a coprocessor. The HBase secondary memory index construction method comprises the following steps: initializing anoriginal HBase data table; initializing a secondary index by using a coprocessor according to the original data table; according to updating of the original data table, updating the secondary index through coprocessor data and constructing a memory index structure; carrying out data table fragmentation operation; initializing a secondary index for the fragmented data table and constructing a memory index structure; and persistently storing the constructed memory index to a disk through a memory persistence method. According to the method, construction and persistent storage of the HBase secondary memory index can be achieved, the defect that a native HBase database only supports non-primary key query in a full-disk scanning mode is overcome, the efficiency of HBase non-primary key retrieval is improved, and the av |
