EXASolution is a parallelized relational database management system (RDBMS) which runs on a cluster of standard computer hardware servers. Following the SPMD model, on each node the identical code is executed simultaneously. The data is stored in a column-oriented way and proprietary in-memory compression methods are used. The company claims that tuning efforts are not necessary since the database includes some kind of automatic self-optimization (like automatic indices, table statistics, and distributing of data).
EXASolution is designed to run in memory, although data is persistently stored on disk following the ACID rules. EXASolution supports the SQL Standard 2003 and can be integrated via standard interfaces like ODBC, JDBC or ADO.NET. Additionally, a SDK is provided for native integration. For OLAP applications, the MDX extension of SQL is supported via ODBO and XMLA.
The license model is based on the allocated RAM for the database software (per GB RAM) and independent to the physical hardware. Customers gain the maximal performance if their compressed active data fits into that licensed RAM, but it can also be much larger.
EXASOL has implemented a so-called cluster operating system (EXACluster OS). It is based on standard Linux and provides a runtime environment and storage layer for the RDBMS, employing a proprietary, cluster-based file system (ExaStorage). Cluster management algorithms are provided like failover mechanisms or automatic cluster installation.
In-database analytics is supported. EXASolution integrates support to run Lua, Java, Python and GNU R scripts in parallel inside user defined functions (UDFs) within the DBMS' SQL pipeline.
