MSThe significant technical features of ESENT include:

· ACID transactions with savepoints, lazy commits and robust crash recovery.

· Snapshot isolation.

· Record-level locking — multi-versioning provides non-blocking reads.

· Highly concurrent database access.

· Flexible meta-data (tens of thousands of columns, tables and indexes are possible).

· Indexing support for integer, floating point, ASCII, Unicode and binary columns.

· Sophisticated index types including conditional, tuple and multi-valued.

· Individual columns can be up to 2GB in size. A database can be up to 16TB in size.

· Can be configured for high performance or low resource usage.

· No administration required (even the database cache size can adjust itself automatically).

· No download. Your application uses the esent.dll which comes with the operating system.
