Product Features
EXASolution runs on a cluster of standard hardware servers. Following the
SPMD model, on each node the identical code is executed simultaneously. The lack of any kind of master node is one reason for the scalability of the product (see also [http://www.tpc.org/tpch/ TPC-H benchmark results] ). Furthermore, EXASolution is designed to run In Memory, although data is persistently stored on disc following the ACID rules.EXASolution supports the and can be integrated via standard interfaces like ODBC, JDBC or ADO.NET. Additionally, a
SDK is provided for native integration.EXASOL has implemented a so called Cluster Operating System (EXACluster OS). It is based on standard Linux and provides functionality for parallel programs. It can be compared to Virtualization, but instead of virtualizing the hardware of a single server, it virtualizes a cluster of nodes to a single one. Intelligent algorithms for cluster management are provided, e.g. failover mechanisms or automatic cluster installation.
The key features of EXASolution can be summarized as follows:
* Shared Nothing Architecture
* Optimized for In Memory Processing
*Column-oriented database
* High Availability through automatic failover mechanismsSee also
