摘要

Abstract

Massive meteorological observations data is the key of the improvement of public weather services'refinement, precision and personalized level. The increased meteorological data can reach to 1 TB every day. The timeless require-ments of large scale meteorological data for its storage, retrieval, transfer and share is a challenge to traditional meteoro-logical information system while based on IOE(IBM, Oracle and EMC)framework. Based on HBase, this paper proposes a structural query optimization using index, named as Hbase4M(HBase for Meteorology). Firstly, the table structure is designed according to the HBase storage property. Secondly, the secondary indexes are established and maintained by HBase coprocessors. It will convert the field query to rowkey search in index table. It also facilitates HBase4M directly to inherit HBase's scalability and low latency and support the flexibility of structure meteorological data query. Experimental results show that the performance of HBase4M can satisfy the demands of meteorological business services.
