Optimising column family for OLAP queries in HBase
International Journal of Big Data Intelligence, 2016Apache HBase is a column-oriented NoSQL key-value store built on top of the Hadoop distributed file-system. Logically, columns in HBase are grouped into column families. Physically, all columns in one column family are stored in the same set of files. Therefore the division of column families is closely related to the response time for a specific row ...

Implementing Joins over HBase on Cloud Platform
2014 IEEE International Conference on Computer and Information Technology, 2014Amount of data and number of database accesses has increased enormously. Traditional databases are unable to fulfil these requirements. Along with the increased amount of data and number of accesses, data is becoming more unstructured. Relational database could not only serve these purposes efficiently but also they add a limitation on the size of data,

HBase runs on HDFS as the underlying filesysystem and benefits from HDFS features such as data reliability, scalability, and replication. HBase stores data as StoreFiles (HFiles) on the HDFS datanodes. HFile represents the file format for HBase. HFile is an HBase-specific file format based on the TFile binary file format.

Performance testing of HBase based on the potential cycle
2013 IEEE/ACIS 12th International Conference on Computer and Information Science (ICIS), 2013With the development and wide application of the computing technology, performance testing becomes more and more important. Real simulation of the user behavior becomes a concern of the performance testing. The paper introduces the potential model to establish the model of the visit amount which can be used in the performance testing.

All names in the Apache HBase shell should be quoted, such as the table name, row key, and column name. Constants don’t need to be quoted. Successful HBase commands return an exit code of 0. But a non-0 exit status does not necessarily indicate failure and could indicate other issues, such as loss of connectivity.

Geospatial data storage based on HBase and MapReduce
2017 6th International Conference on Agro-Geoinformatics, 2017Traditional relational database management systems (RDBMS) have shown limitations in storing and analyzing big data. For example, a RDBMS is suitable for transactional operations yet not good at large-scale data analysis and processing, since a large-scale record scan or full table scan is often time-consuming.

A query method for domain ontology based on HBase
2017 13th International Conference on Natural Computation, Fuzzy Systems and Knowledge Discovery (ICNC-FSKD), 2017To address the problem of distributed query in the domain ontology of civil aviation emergency, this paper proposed a distributed storage and a query method of domain ontology based on HBase. It adopted a method for storing domain ontology metadata and RDF instance data separately.

A hybrid index for multi-dimensional query in HBase
2016 4th International Conference on Cloud Computing and Intelligence Systems (CCIS), 2016With the explosive growth of data, distributed databases are widely used in various applications, including e-commerce, social networking, recommendation system, location-based service and etc. Among them, the use of HBase is the most common. However, it does not natively support multi-dimensional query and the existing multi-dimensional index ...

Social Network Path Analysis Based on HBase
2013Online social network services have become indispensable in people’s daily life. The analysis of data in social network services often involves data mining techniques. However, the quick increase of users in such services posts challenges to develop effective data mining algorithms to deal with large social network data.
