Күн бұрын

Redis is a noSQL key-value store, in memory database first that exploded in popularity in the past few years. In this video slash course, we will explain what Redis is, talk about the in-memory model, the optional durability, replication, clustering publish subscribe and the protocol and finally we will go through examples. During the video I will add time codes to each topic so you guys can jump to the topic that interests you the most.

Hello Nasser, your content is brilliant and the way you talk and present tops it. Its like having a coffee table discussion with you about a topic(my role being a good listener). I leant a lot of concepts at its core. I have been looking for a content like this for long. Big thanks man!

I did not have seen that many tutorials/crash course as good as yours to follow!😁 for me it was perfect. Entertaining and still got all the Infos I wanted/needed. Thank you! Keep on!

Great video Hussein. The first in-memory database I worked on a couple of years back was TimesTen. We usually use this along with the main Oracle DB for caching aggregates. You can sync data, mostly aggregates for faster reporting defaulted to that particular aggregation hierarchy.

Great video, very infomative, I love your style. Here are my 2 cents about HTTP vs TCP: If I was designing a DBMS I would also use TCP. HTTP uses TCP in the background. TCP keeps permanently open socket connection, whereas HTTP closes the socket connection after each request/response cycle, and that adds overhead to communication. Also with TCP you can have just as much security as with HTTP with TLS, since it's the same underlying principle.

redis is simple to install, configure and use , with sdk s available for all major programming languages and good performance out of the box. it’s no surprises we all love it.

Doesn't Http use tcp? You are comparing an application layer with transport layer. I guess Resp and Http are comparable. Correct me if wrong.

@avatsavirs 3 жыл бұрын

28:00 TCP and HTTP aren't competing protocols. TCP is a transport layer protocol and HTTP is an application layer protocol. In fact HTTP uses TCP in transport layer.

@ladmerc 3 жыл бұрын

I think he didn't insinuate that they're competing. As you mentioned, HTTP is built on top of TCP so there's always going to be some overhead when using HTTP instead of TCP. For example, HTTP would parse headers, format of data etc I think what he's curious about is if these overheads outweigh the benefits of using HTTP

@muhaimintaib 3 жыл бұрын

@@ladmerc agreed. He’s just wondering why most other databases (not all) are creating their own protocol on top of raw TCP (this is what Redis does), instead of just using the new HTTP/2 where you can keep the TCP connection open and streams requests back and forth. Using QUIC (soon to be HTTP/3) is also an option.

Hey! Hussain. How about collaborating on building an Http based Database? 😎

hi, Hussein i have a question and it will not take long to answer so, plesase answer it question: just after completing high school i had purchased a web development course and learned a lot. After some 3-4 months i endup with a job. It is now 4 months of job. at this point i am enjoying and also learning a lot from nice gurus like you. But i want to go more deeper into computer science like how operating systems, db systems, cpu executes instructions works, do i need to join college to learn all these stuffs or i can learn by my own by joining some good community, opensource, reading book etc.

You can learn them by yourself. Hussein himself has courses for both db & os fundamentals.

Imagine, REDIS with non volatile memory, like the future ReRAM as your storage.....the perfect match, Millions of Rps on a commodity server. Everybody will choose REDIS and the infrastructure will be simplier (no more cache all in non volatile memory accessible in sub millisecond). For me, REDIS with ReRAM is the futur. No need of Snapshop or AOF, no care about the size of the memory, the dream.

What about streams ?

@mohamedhabas7391 3 жыл бұрын

They are quite trikey , I have been hunting for a way to deal with them , the only approach I found is people using custom data frames and processing them as a sequence of json strings. I wish if someone is familiar with dealing with streams would give his/her opinion

@@mohamedhabas7391 the few videos I have looked are examples of how to use them but no real use case the video are with Salvatore Sanfilippo himself (2 years ago) he does it quickly in vim in front of us but not only he is well prepared but we can imagine that he knows intrinsically what he is talking about
