Transactions

A transaction is a sequence of SQL operations that starts with the START TRANSACTION statement and ends with the COMMIT statement. Either the effect of all operations will be published, or no results will be published at all.

warning

Transaction control statements are only allowed within a script.

In Apache Ignite 3, you start the transaction by using the START TRANSACTION statement:

note

DDL statements are not supported inside transactions.

Parameters:

  • READ WRITE - both read and write operations are allowed in the transaction. Used by default.
  • READ ONLY - only read operations are allowed in the transaction.

You close and commit the transaction by using the COMMIT statement:

Example​

The example below inserts 3 lines into the table in a single transaction, ensuring they will all be committed together:

START TRANSACTION READ WRITE;

INSERT INTO Person (id, name, surname) VALUES (1, 'John', 'Smith');
INSERT INTO Person (id, name, surname) VALUES (2, 'Jane', 'Smith');
INSERT INTO Person (id, name, surname) VALUES (3, 'Adam', 'Mason');

COMMIT;
