Transactions are a robust concept to ensure your queries are executed,
even if network errors occur. To do this, simply use the transaction
method on EdgeDBClient.
client.transaction(tx ->
tx.execute("INSERT Person { name := $name, age := $age}", new HashMap<>(){{
put("name", "Example Name");
put("age", 1234);
}}).thenCompose(v ->
tx.querySingle(Long.class, "SELECT count((SELECT Person))");
);
).thenAccept(count -> {
System.out.println(String.format("There are %d people in the database", count));
})It is important to note that you must use the tx parameter of the
transaction to preform queries, otherwise you won’t get the benefits
of transactions.
