Module :
transactions
Version : 0.5.0
Module overview
This module provides Ballerina transaction manager implementation.
The code snippet given below uses the functions in the module to get the transaction information.
NOTE: This module is deprecated from 2.0.0-preview1 onwards. Please use lang.transaction module instead.
// When the `transaction` statement starts, a distributed transaction context is created.
transaction {
// Print the current transaction ID
log:printInfo("Started transaction: " +
transactions:getCurrentTransactionId());
// When a participant is called, the transaction context is propagated, and that participant
// gets infected and joins the distributed transaction.
boolean successful = callBusinessService();
if (successful) {
log:printInfo("Business operation executed successfully");
} else {
log:printError("Business operation failed");
abort;
}
// As soon as the `transaction` block ends, the `2-phase commit
// coordination` protocol will run. All participants are prepared
// and depending on the joint outcome, either a `notify commit` or
// `notify abort` will be sent to the participants.
} committed {
log:printInfo("Initiated transaction committed");
} aborted {
log:printInfo("Initiated transaction aborted");
}
