QueueDatabaseConfig Fields
QueueDatabaseConfig Class See Also Send Feedback

The QueueDatabaseConfig type exposes the following members.

# Fields

| Name | Description
--- | --- | ---
| Append | A function to call after the record number has been selected but before the data has been stored into the database.
| 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.)
| 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 -- that is, the cache. (Inherited from DatabaseConfig.)
| ConsumeInOrder | If true, modify the operation of Consume(Boolean) to return key/data pairs in order. That is, they will always return the key/data item from the head of the queue.
| 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.)
| 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 | Cause 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.)
| 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.)
