ESENT

ESENT is an embeddable transactional database engine. It was delivered for the first time with Microsoft Windows 2000 and has been available to developers since then. You can use ESENT for applications that require reliable, efficient and economical storage of structured or semi-structured data. The ESENT engine can meet data needs ranging from something as simple as a hash that is too large to be stored in memory to something more complex, such as an application with tables, columns, and indexes.

  • Indexing support for integer, floating-point, ASCII, Unicode, and binary columns.
  • Sophisticated index types, including conditional, tuple, and multi-value.
  • Columns up to 2 GB with a maximum database size of 16 TB.

Benefits
