/**
 * 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 to limit query/transaction execution time. Specified timeout overrides the default timeout
 * configured in the database using `dbms.transaction.timeout` setting. Value should not represent a duration of zero or negative duration.
 * @property {Object} metadata - the transaction metadata. Specified metadata will be attached to the executing transaction and visible in the output of
 * `dbms.listQueries` and `dbms.listTransactions` procedures. It will also get logged to the `query.log`. This functionality makes it easier to tag
 * transactions and is equivalent to `dbms.setTXMetaData` procedure.
