executeBatch的机制：事务还是管道？

Question

在MySQL中，executeBatch似乎不像事务。

它是否像Redis中的管道一样提高了性能？

更新

这两种用法之间是否有任何性能差异？

一个。的executeUpdate

try (PreparedStatement ps = conn.prepareStatement("INSERT INTO test (key_, value_) VALUES (?, ?)") {
    ps.setString(1, "key1");
    ps.setString(2, "value1");
    ps.executeUpdate();
    ps.setString(1, "key2");
    ps.setString(2, "value2");
    ps.executeUpdate();
}

湾addBatch /则ExecuteBatch

try (PreparedStatement ps = conn.prepareStatement("INSERT INTO test (key_, value_) VALUES (?, ?)")) {
    ps.setString(1, "key1");
    ps.setString(2, "value1");
    ps.addBatch();
    ps.setString(1, "key2");
    ps.setString(2, "value2");
    ps.addBatch();
    ps.executeBatch();
}
