/**
* Configuration object containing settings for explicit and auto-commit transactions.
* <p>
* Configuration is supported for:
* <ul>
* <li>queries executed in auto-commit transactions using {@link Session#run} and {@link RxSession#run}</li>
* <li>transactions started by transaction functions using {@link Session#readTransaction}, {@link RxSession#readTransaction},
* {@link Session#writeTransaction} and {@link RxSession#writeTransaction}</li>
* <li>explicit transactions using {@link Session#beginTransaction} and {@link RxSession#beginTransaction}</li>
* </ul>
* @typedef {Object} TransactionConfig
* @property {number} timeout - the transaction timeout in **milliseconds**. Transactions that execute longer than the
* configured timeout will be terminated by the database. This functionality allows user code to limit
* query/transaction execution time. The specified timeout overrides the default timeout configured in the database
* using the `db.transaction.timeout` setting (``dbms.transaction.timeout`` before Neo4j 5.0). Values higher than
* `db.transaction.timeout` will be ignored and will fall back to the default for server versions between 4.2 and 5.2
* (inclusive). The value should not represent a negative duration. A timeout of `0` will make the transaction execute
* indefinitely. `null` (default) will use the default timeout configured on the server.
* @property {Object} metadata - the transaction metadata. Specified metadata will be attached to the executing transaction and visible in the output
* of `SHOW TRANSACTIONS YIELD *`. It will also get logged to the `query.log` file. This functionality makes it easier to tag transactions and is
* equivalent to the `dbms.setTXMetaData` procedure, see https://neo4j.com/docs/cypher-manual/current/clauses/transaction-clauses/#query-listing-transactions
* and https://neo4j.com/docs/operations-manual/current/reference/procedures/ for reference.
