Thank you for the feedback. This is not a common concept, but you can use whenever you have find similar data from database which are of big size or volume it too high. Thank you for sharing the feedback.
I have one naive doubt, I have a pyhton project, and have a virtual env for that, also I have the file that I want to run in my dag in that project, how to use the same venev for airflow? Or is there any other way using two different envs?
Is there any way I can do this on my entire computer? I have failed uploads/downloads in games such as VRChat and also with my web browser, such as what was covered in this video. This did fix my problems I had downloading items off of my browser so Thank you very much :)
I am trying to reproduce the same steps in my machine. I am not able to find Student table under Northwind database. Can you please where I can find the scripts for that? This video is starting to be very useful for me.
The demonstrated platform responsiveness for ingesting just a few dummy records is absolutely disappointing. Also don’t really get what multiple comments like “wait for couple of minutes” has to do while you are presenting streaming solution claiming sub second operational processing !
when I execute copy comments , I got this error "ERROR: invalid byte sequence for encoding "WIN1251": 0xff CONTEXT: COPY paymentmastervisa, line 1 " Can you help me ?
SIMILAR CODE FROM CHATGPT Certainly! Here's an example code that demonstrates how to achieve inter-process communication using memory mapped files and event handlers in C#. This code assumes you have two Windows Forms projects: a sender project and a receiver project. Sender Project (Windows Forms): csharp Copy using System; using System.IO.MemoryMappedFiles; using System.Text; using System.Threading; using System.Windows.Forms; namespace SenderProject { public partial class SenderForm : Form { private MemoryMappedFile memoryMappedFile; private EventWaitHandle eventWaitHandle; public SenderForm() { InitializeComponent(); InitializeMemoryMappedFile(); } private void InitializeMemoryMappedFile() { memoryMappedFile = MemoryMappedFile.CreateOrOpen("MyMemoryMappedFile", 1000); eventWaitHandle = new EventWaitHandle(false, EventResetMode.AutoReset, "MyEvent"); } private void SendMessage(string message) { using (var accessor = memoryMappedFile.CreateViewAccessor()) { byte[] buffer = Encoding.ASCII.GetBytes(message); accessor.WriteArray(0, buffer, 0, buffer.Length); } eventWaitHandle.Set(); // Signal the event to notify the receiver } private void textBoxMessage_TextChanged(object sender, EventArgs e) { string message = textBoxMessage.Text; SendMessage(message); } } } Receiver Project (Windows Forms): csharp Copy using System; using System.IO.MemoryMappedFiles; using System.Text; using System.Threading; using System.Windows.Forms; namespace ReceiverProject { public partial class ReceiverForm : Form { private MemoryMappedFile memoryMappedFile; private EventWaitHandle eventWaitHandle; private Thread receiveThread; public ReceiverForm() { InitializeComponent(); InitializeMemoryMappedFile(); InitializeEventHandling(); } private void InitializeMemoryMappedFile() { memoryMappedFile = MemoryMappedFile.CreateOrOpen("MyMemoryMappedFile", 1000); eventWaitHandle = EventWaitHandle.OpenExisting("MyEvent"); } private void InitializeEventHandling() { receiveThread = new Thread(ReceiveMessage); receiveThread.Start(); } private void ReceiveMessage() { while (true) { eventWaitHandle.WaitOne(); // Wait for the event to be signaled using (var accessor = memoryMappedFile.CreateViewAccessor()) { byte[] buffer = new byte[1000]; accessor.ReadArray(0, buffer, 0, buffer.Length); string message = Encoding.ASCII.GetString(buffer).Trim('\0'); HandleMessage(message); } } } private void HandleMessage(string message) { // Invoke UI update on the main UI thread textBoxReceivedMessage.Invoke((MethodInvoker)delegate { textBoxReceivedMessage.Text = message; }); } } } In the sender project, you can create a Windows Forms application and add a TextBox control named textBoxMessage. Attach the textBoxMessage_TextChanged event handler to the TextChanged event of the textBoxMessage. In the receiver project, create another Windows Forms application and add a TextBox control named textBoxReceivedMessage.
Hello. Error = [Microsoft][ODBC Driver 13 for SQL Server]Unable to open BCP host data-file. I'm getting this type of error in step 3, while exporting the data. Please provide solution if any.
