Interface ITwoPhaseCommit

An interface for implementations that support 2-phase commit. You can use TwoPhaseCommitTool to execute a 2-phase commit algorithm over several ITwoPhaseCommits.

Note

This API is experimental and might change in incompatible ways in the next release.

Namespace: Lucene.Net.Index

Assembly: Lucene.Net.dll

Syntax

public interface ITwoPhaseCommit

Methods

Commit()

The second phase of a 2-phase commit. Implementations should ideally do very little work in this method (following PrepareCommit(), and after it returns, the caller can assume that the changes were successfully committed to the underlying storage.

Declaration

void Commit()

PrepareCommit()

The first stage of a 2-phase commit. Implementations should do as much work as possible in this method, but avoid actual committing changes. If the 2-phase commit fails, Rollback() is called to discard all changes since last successful commit.

Declaration

void PrepareCommit()

Rollback()

Discards any changes that have occurred since the last commit. In a 2-phase commit algorithm, where one of the objects failed to Commit() or PrepareCommit(), this method is used to roll all other objects back to their previous state.

Declaration

void Rollback()
