The SecondaryBTreeDatabase type exposes the following members.

# Properties

| Name | Description
--- | --- | ---
| AutoCommit | If true, all database modification operations based on this object will be transactionally protected. (Inherited from BaseDatabase.)
| CacheSize | The size of the shared memory buffer pool -- that is, the cache. (Inherited from BaseDatabase.)
| Compare | The Btree key comparison function. The comparison function is called whenever it is necessary to compare a key specified by the application with a key currently stored in the tree.
| Creation | The CreatePolicy with which this database was opened. (Inherited from BaseDatabase.)
| DatabaseName | The name of this database, if it has one. (Inherited from BaseDatabase.)
| DoChecksum | If true, do checksum verification of pages read into the cache from the backing filestore. (Inherited from BaseDatabase.)
| DupCompare | The duplicate data item comparison function.
| Duplicates | Whether the insertion of duplicate data items in the database is permitted, and whether duplicates items are sorted.
| EncryptAlgorithm | The algorithm used by the Berkeley DB library to perform encryption and decryption. (Inherited from BaseDatabase.)
| Encrypted | If true, encrypt all data stored in the database. (Inherited from BaseDatabase.)
| Endianness | The database byte order. (Inherited from BaseDatabase.)
| ErrorFeedback | The mechanism for reporting detailed error messages to the application. (Inherited from BaseDatabase.)
| ErrorPrefix | The prefix string that appears before error messages issued by Berkeley DB. (Inherited from BaseDatabase.)
| Feedback | Monitor progress within long running operations. (Inherited from BaseDatabase.)
| FileName | The filename of this database, if it has one. (Inherited from BaseDatabase.)
| FreeThreaded | If true, the object is free-threaded; that is, concurrently usable by multiple threads in the address space. (Inherited from BaseDatabase.)
| HasMultiple | If true, the object references a physical file supporting multiple databases. (Inherited from BaseDatabase.)
| InHostOrder | If true, the underlying database files were created on an architecture of the same byte order as the current one. This information may be used to determine whether application data needs to be adjusted for this architecture or not. (Inherited from BaseDatabase.)
| KeyGen | The delegate that creates the set of secondary keys corresponding to a given primary key and data pair. (Inherited from SecondaryDatabase.)
| MinKeysPerPage | The minimum number of key/data pairs intended to be stored on any single Btree leaf page.
| NoMMap | If true, this database is not mapped into process memory. See MMapSize for further information. (Inherited from BaseDatabase.)
| NonDurableTxns | If true, Berkeley DB will not write log records for this database. (Inherited from BaseDatabase.)
| Nullifier | (Inherited from SecondaryDatabase.)
| Pagesize | The database's current page size. (Inherited from BaseDatabase.)
| PrefixCompare | The Btree prefix function. The prefix function is used to determine the amount by which keys stored on the Btree internal pages can be safely truncated without losing their uniqueness.
| Priority | The cache priority for pages referenced by this object. (Inherited from BaseDatabase.)
| ReadOnly | If true, this database has been opened for reading only. Any attempt to modify items in the database will fail, regardless of the actual permissions of any underlying files. (Inherited from BaseDatabase.)
| ReadUncommitted | If true, this database supports transactional read operations with degree 1 isolation. Read operations on the database may request the return of modified but not yet committed data. (Inherited from BaseDatabase.)
| RecordNumbers | If true, this object supports retrieval from the Btree using record numbers.
| ReverseSplit | If false, empty pages will not be coalesced into higher-level pages.
| Transactional | If true, this database has been opened in a transactional mode. (Inherited from BaseDatabase.)
| Truncated | If true, the underlying file was physically truncated upon open, discarding all previous databases it might have held. (Inherited from BaseDatabase.)
| Type | The type of the underlying access method (and file format). This value may be used to determine the type of the database after an Open(String, DatabaseConfig). (Inherited from BaseDatabase.)
| UseMVCC | If true, the database was opened with support for multiversion concurrency control. (Inherited from BaseDatabase.)
