Defines the action to perform when opening a BPlusTree with an existing log file.

Syntax

Visual Basic (Declaration)
Public Enum ExistingLogAction Inherits System.Enum

C#
public enum ExistingLogAction : System.Enum

Members

Member	Description
Default	Infers the default wether or not the data file was created. For newly created data files (CreatePolicy = Always, or IfNeeded and the file is missing) the default will be Truncate. When existing data files are opened the default will ReplayAndCommit.

Replay	Replay the log entries uncommitted
ReplayAndCommit	Replay the log entries and commit the changes to the store
Truncate	Ignore the existing entries and truncate the log
