Class BulkDataPersisterContext

java.lang.Object
com.j_spaces.sadapter.datasource.BulkDataPersisterContext
public class BulkDataPersisterContext extends Object
BulkDataPersisterContext an operation context that is accessible on mirror in BulkDataPersister.executeBulk(List) method.
BulkDataPersisterContext is not accessible on any other space except mirror and not in any other method except BulkDataPersister.executeBulk(List)

Example of mirror implementation: 

 public void executeBulk(List bulk) throws DataSourceException {
 BulkDataPersisterContext context = BulkDataPersisterContext.getCurrentContext();

 if (context.isConsolidatedDistributedTransaction()) {
 // Built-in consolidation using multi-source replication mode
 ConsolidatedDistributedTransactionMetaData metadata = getConsolidatedDistributedTransactionMetaData();
 TransactionUniqueId transactionId = metadata.getTransactionUniqueId();
 int participantsCount = metadata.getParticipantsCount();

 } else if (context.isTransactional()) {
 // Single participant transaction or distributed transaction failed to be consolidated
 TransactionParticipantMetaData metadata getTransactionParticipantMetaData();
 TransactionUniqueId transactionId = metadata.getTransactionUniqueId();
 int participantsCount = metadata.getParticipantsCount();
 int participantId = metadata.getParticipantId();

 // Identify failed to consolidate transaction
 if (participantsCount > 1) {
 ...

 } else {
 // Single participant transaction...

 }

 } else {
 // Regular execution (no transaction)
 ....
 }

 }

      Resets the current context

    • getTransactionData

      @Deprecated public TransactionParticipantData getTransactionData()
      Deprecated.
      since 9.0.1 - use getTransactionParticipantMetaData() instead.
      Gets transaction participant data if exists.

    • getTransactionParticipantMetaData

      public String getSourceSpaceMemberName()
      Get the source space member name that sent this bulk.

    • isTransactional

      public boolean isTransactional()
      Returns:
      Whether the current context is transactional.

    • isConsolidatedDistributedTransaction
