Tiivistelmä (eng): | The scalability of a database is an important issue for applications that deal with large amounts of data, such as web services. The presence of rapidly increasing high-volume data sets is a phenomenon commonly known as Big Data. As an alternative to traditional relational databases, the so-called NoSQL distributed databases have proved to be robust in Big Data applications. Most NoSQL databases, such as Bigtable and HBase, do not depend on high-end hardware, but are designed to easily scale by distributing the workload to a set of servers with conventional hardware. Cloud Computing infrastructures are suitable for these databases. HBase focuses on offering scalability and thus does not provide transactions with ACID (atomicity, consistency, isolation, durability) properties. Recently, however, there have been ~any attempts towards supporting ACID transactions in these databases. One important application of this feature is the support for incremental updates to a data repository, such as a web search index. Most of the existing transactional systems for HBase are built on top of HBase itself, with transactional metadata in the database and algorithms in the client-side. We have built HAcid, a new open-source transactional system for HBase. As most similar existing systems, it is a client library that keeps transactional metadata in HBase to avoid introducing new server-side software. The novelty of HAcid is its lightweight characteristics: it uses minimal bookkeeping resources and is straightforward to install. The purpose is not to minimize transaction latency, but to provide an easy approach to ACID transactions in HBase. |
