An Efficient Row Key Encoding Method with ASCII Code for Storing Geospatial Big Data in HBase
2020
ISPRS International Journal of Geo-Information
Preserved Fulltext
In this paper, we propose a new row key encoding method instead of conventional stereotypes. ...
that the proposed method can not only maintain an equivalent query speed but can shorten the row key and save storage resources by 20.69% compared with the original grid codes. ...
We found that the prefixtree method would have a greater apparent efficiency for the experimental data used in this paper compared with the proposed row key encoding method. ...
