BTreeDatabaseConfig Class See Also Send Feedback

The BTreeDatabaseConfig type exposes the following members.

# Fields

| Name | Description
--- | --- | ---
| AutoCommit | Enclose the open call within a transaction. If the call succeeds, the open operation will be recoverable and all subsequent database modification operations based on this handle will be transactionally protected. If the call fails, no database will have been created. (Inherited from DatabaseConfig.)
| BlobDir | The path of the directory where blobs are stored. If the database is opened within DatabaseEnvironment, this path setting will be ignored during Open(String, BTreeDatabaseConfig). Use BlobDir to identify the current storage location of blobs after opening the database.
| BTreeCompare | The Btree key comparison function.
| BTreePrefixCompare | The Btree prefix function.
| ByteOrder | The byte order for integers in the stored database metadata. The host byte order of the machine where the Berkeley DB library was compiled is the default value. (Inherited from DatabaseConfig.)
| CacheSize | The size of the shared memory buffer pool (the cache). (Inherited from DatabaseConfig.)
| Creation | The policy for how to handle database creation.
| DoChecksum | If true, do checksum verification of pages read into the cache from the backing filestore. (Inherited from DatabaseConfig.)
| DuplicateCompare | The duplicate data item comparison function.
| Duplicates | Policy for duplicate data items in the database. Allows a key/data pair to be inserted into the database even if the key already exists.
| Env | The Berkeley DB environment within which to create a database. If null, the database will be created stand-alone; that is, it is not part of any Berkeley DB environment. (Inherited from DatabaseConfig.)
| ErrorFeedback | The mechanism for reporting error messages to the application. (Inherited from DatabaseConfig.)
| ErrorPrefix | The prefix string that appears before error messages issued by Berkeley DB. (Inherited from DatabaseConfig.)
| Feedback | (Inherited from DatabaseConfig.)
| FreeThreaded | Causes the database object to be free-threaded; that is, concurrently usable by multiple threads in the address space. (Inherited from DatabaseConfig.)
| NoMMap | Do not map this database into process memory. (Inherited from DatabaseConfig.)
| NonDurableTxns | If true, Berkeley DB will not write log records for this database. (Inherited from DatabaseConfig.)
| NoReverseSplitting | Turn reverse splitting in the Btree on or off.
| NoWaitDbExclusiveLock | Configuration of BaseDatabase handle to obtain a write lock on the entire database. (Inherited from DatabaseConfig.)
| Priority | The cache priority for pages referenced by the database. (Inherited from DatabaseConfig.)
| ReadOnly | Open the database for reading only. Any attempt to modify items in the database will fail, regardless of the actual permissions of any underlying files. (Inherited from DatabaseConfig.)
| ReadUncommitted | Support transactional read operations with degree 1 isolation. (Inherited from DatabaseConfig.)
| Truncate | Physically truncate the underlying file, discarding all previous databases it might have held. (Inherited from DatabaseConfig.)
| UseMVCC | Open the database with support for multiversion concurrency control. (Inherited from DatabaseConfig.)
| UseRecordNumbers | If true, support retrieval from the Btree using record numbers.
