Understanding DynamoDB Hash and Range Keys in Java
Hey everyone! 🚀 Today, I want to share some insights on how to query DynamoDB using hash and range keys.
When using DynamoDB, having a good understanding of partition keys (hash keys) and sort keys (range keys) is crucial for efficient queries. Here's a quick breakdown:
- Hash Key: Uniquely identifies an item in a table. - Range Key: Allows multiple items with the same hash key, differentiated by this key.
To query using these keys in Java, you can use the AWS SDK like this:
This setup gives you fine control over your data retrieval. Don't hesitate to dive deeper into AWS docs, and practice querying your own DynamoDB tables! 📚✨

You can’t. What you can do, though, is use WhatsApp’s and Telegram’s web platforms to transfer stickers. It’s easy, but might take a while.Open WhatsApp in your browser, find a sticker you like in a chat, and right-click on it to save it as an image. The file won’t be a picture, though—it’s a webpage and will have a .webp extension. Don’t be scared, this is the way. Repeat this step to save as many stickers as you want.Then, open Telegram in your browser and go into your Saved messages chat. Just as you’d share a file with a friend, click the Share file button on the bottom left of the chat window (it looks like a dog-eared paper), and select the .webp files you downloaded. Click Open and you’ll see your stickers in your Saved messages chat. This is now your sticker depository. To use them, forward them as you would a message from one chat to the other: by clicking or long-pressing on the sticker, and then choosing Forward.
Unlimited members in Telegram group now
Telegram has made it easier for its users to communicate, as it has introduced a feature that allows more than 200,000 users in a group chat. However, if the users in a group chat move past 200,000, it changes into "Broadcast Group", but the feature comes with a restriction. Groups with close to 200k members can be converted to a Broadcast Group that allows unlimited members. Only admins can post in Broadcast Groups, but everyone can read along and participate in group Voice Chats," Telegram added.
