SecondaryQueueDatabaseConfig Fields

BerkeleyDB

The SecondaryQueueDatabaseConfig type exposes the following members.

Fields

  NameDescription
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.)
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.)
ImmutableKey
If true, the secondary key is immutable.
(Inherited from SecondaryDatabaseConfig.)
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.)
Populate
If true and the secondary database is empty, walk through Primary and create an index to it in the empty secondary. This operation is potentially very expensive.
(Inherited from SecondaryDatabaseConfig.)
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.)
