Very good video series, I love that you took time to illustrate the different examples. I have a question.. instead of creating different tables with the cluster key of ascending/descending order.. is it possible for cassandra to do SQL like queries where SELECT * FROM simple_temp_v2 ORDER BY time_created ASC Cheers

Hi, so this is my JSON to create debezium connector but it returned error. Could you please help me troubleshoot? I am still learning and already look out for the solving but to no avail. Y^Y JSON: { "name": "source-transactions-connector", "config": { "connector.class": "io.debezium.connector.postgresql.PostgresConnector", "plugin.name": "pgoutput", "database.hostname": "postgres", "database.port": "5432", "database.user": "etl", "database.password": "demopass", "database.dbname": "dvdrental", "database.server.name": "postgres", "key.converter.schemas.enable": "false", "value.converter.schemas.enable": "false", "transforms": "unwrap", "transforms.unwrap.type": "io.debezium.transforms.ExtractNewRecordState", "key.converter": "org.apache.kafka.connect.json.JsonConverter", "value.converter": "org.apache.kafka.connect.json.JsonConverter", "table.include.list": "public.rental_streaming", "slot.name": "deb_rental_transaction_slot" } } ERROR: ERROR || Failed testing connection for jdbc:postgresql://postgres:5432/dvdrental with user 'etl': The connection attempt failed.

You can combine the inventory and rate tables

can you make a video on streaming data from cassandra to kafka using debezium

The note pdf is not available. Can you reupload it? Thanks.

Thank you

How would this system handle scalability? For example if we need to horizontally scale the rate limiter service.

Thank you for the great tutorial! I really appreciate it. I did find the background music a bit distracting-would you mind considering leaving it out in the future?

Amazing, thank you

Tooltip doesn't work now on v5

Hello, great video. I am interested in taking this entire course. However, I am having trouble figuring out the arrangement/progression of the entire course in your playlist. Please could you kindly number each of the videos in this series (e.g. #0, #1, etc.) or perhaps reorganise the playlist? This would really help me and others who are finding it difficult to know the correct sequence to follow. Thank you.

Why do we need both unique checkout_id and token? Shouldn't the unique checkout_id be good enough?

Scheduled job won't work if the consumers logs in after 1 year

I just heard of Debezium few months ago because we use it at work. Your explanation was clear. Thank you!

Is there a way to shut down the background music?

Awesome, Make a complete RAG application with some text file.

Hi this is Faruk from India, You are doing awesome.

Love it!

Im try this command "docker run --tty --network postgres_debezium_cdc_default confluentinc/cp-kafkacat kafcakat -b kafka:9092 -C -s key=s -s value=avro -r schema-registry:8081 -t postgres.public.student" and get issue => docker: Error response from daemon: network postgres_debezium_cdc_default not found. When i check docker network im found this network, ee5c820a3e14 debezium-network bridge local b4dadb00d632 debezium_default bridge local when im tried using one of them, get issue: docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "kafcakat": executable file not found in $PATH: unknown. how to solve?

How did you get umami.track to work? It says it's missing umami installation

great tutorial. Used Claude AI to figure out the dependencies and how to setup the OpenAI API Key for the simple_prompts file.

thank you very much. i really appreciate your approach to discussing this topic

Welcome back! This is amazing, very informative, and easy to understand

so this is transactional replication but for each individual table?

I am sorry but that bgm is really irking me

Woow, you have even shared your noted!! That's perfectly perfect!

Thank you so much Irtiza, that's pure Gold content!! Every sec was full of informarion!! Subscribed!

As a Frontend dev, you're videos have been pivotal in my understanding system design. You explain everything so well! I wish you had more fullstack SD videos... I could watch your videos all day!

Wow, this is one of the best videos on system design I've seen. This was super well organized and thought out. I really appreciate the clear explanations!

Okay, so I'm rewatching this. We said at the beginning that guests are not booking actual rooms rather, it is a room type they are booking, that makes sense. Now the issue of multiple guests booking the same seems irrelevant here, dont you think. A reservation is for a particular room type in a particular hotel. For example Hotel XYZ has 50 King Size Room types, recorded in the room_type_inventory table yeah? So if guest A books one of such room types in Hotel XYZ, we have 49 left right? At this point guest A has no idea what the room number is until they are checking in, most likely at the hotel front desk. So what I am saying is, guests booking the same room does not apply, since they are only able to book a room type in advance. What am I missing?

11:50 let me clarify, this is a very compound PRIMARY KEY <PARTITION KEY, league, kit_number, position, goals> with a PARTITION KEY <name, club>?

Amazing videos and great explanations. Awaiting for new videos.

Mentioning the consistent hash ring should be a necessity for intro to cassandra videos

Another question partaining to partioning. So one of the functional requirements is that a user should be able to search for a room by a given date range. Would it be right to partition the table in question by date field?

Great!

In the case where multiple users are trying to make a booking or reservation for the same room, wont the reservation status suffice instead of using the optimistic locking approach or db constraint? Let's say the status is an enum {'available', 'pending', 'payment_completed'} as an example, if the status is not `available` then it can be reserved. Wouldn't that be sufficient to avoid multiple booking?

Thank you :)

the best explanation

can i used this design for RAG system in production for real time update postgres to vector database?

Lots of conflict in your talk. If user A pushes its message to its channel, and A's subscribers go to pull the message themselves, why does A need to look up which friend is online and then determine if A needs to push message or not.

Mine is saying no module named redis. So how do I troubleshoot it??

Stanton View

Can you do api calls with the self host version?

Thank you, this was a basic demo, but a really good one!
