ESENT
ESENT is an integrable transactional database engine. It first shipped with Microsoft Windows 2000 and has been available to developers since then. You can use ESENT for applications that require reliable, high-performance, low-overhead storage of structured or semi-structured data. The ESENT engine can meet data needs ranging from something as simple as a hash table that is too large to store in memory, to something more complex like an application with tables, columns, and indexes.
Active Directory, Windows Desktop Search, Windows Mail, Live Mesh, and Windows Update currently rely on ESENT for data storage. And Microsoft Exchange stores all of its mailbox data (a large server typically has tens of terabytes of data) using a slightly modified version of ESENT code.
Characteristics
The main technical characteristics of ESENT include:
- ACID transactions with savepoints, lazy commits, and robust disaster recovery.
- Snapshot isolation.
- Record-level locking (multi-versioning provides non-blocking reads).
- Highly concurrent database access.
- Flexible metadata (tens of thousands of columns, tables and indexes are possible).
- Indexing support for integer, float, ASCII, Unicode, and binary columns.
- Sophisticated index types, including conditional, tuple, and multivalued.
- Columns up to 2 GB with a maximum database size of 16 TB.
Benefits
- No additional downloads needed. ManagedEsent uses the native esent.dll which is already part of every version of Microsoft Windows.
- No administration required. ESENT automatically manages log files, database recovery, and even database cache size.
Note: ESENT database file cannot be shared among multiple processes simultaneously. ESENT works best for applications with simple, predefined queries; if you have an application with complex ad hoc queries, a storage solution that provides a query layer will work best for you.
