All Implemented Interfaces:

Serializable

public final class TransactionConflictException
extends TransactionFailedRetriableException

Thrown if there is a conflict detected when a transaction is committed. If two concurrent transactions make calls to Transaction.put(TableReference, java.util.Map) or Transaction.delete(TableReference, Set) for the same Cell, then this is a write-write conflict.

The error message should be detailed about what caused the failure and what other transaction conflicted with this one.

Method Detail

getSpanningWrites

public Collection<TransactionConflictException.CellConflict> getSpanningWrites()

These conflicts had a start timestamp before our start and a commit timestamp after our start.

getDominatingWrites

public Collection<TransactionConflictException.CellConflict> getDominatingWrites()

These conflicts started and committed after our start timestamp. Having these kinds of conflicts means that we may be a long running transaction.

getConflictingTable

public TableReference getConflictingTable()

create

public static TransactionConflictException create(TableReference tableRef,
                                                  long timestamp,
