This is the first time I feel like I understand how elasticsearch works. I was looking for good foundations, and I find them - very clear and great idea about the quiz !
Liked your presentation. Proper Introduction to all components of Elastic stack and then moving into Elasticsearch made it easier to understand/visualize whole ecosystem.
The lecture is very good 👍📌 I could answer all the quiz questions in the end, But I thing it would appropriate if you add to title of the tutorial that it's more suitable to architects or DevOps.
i have a question, at 10:00 it talks about the inverted index and i get the idea, however i'm confused about the document it doesn't look like a JSON document which is the kind of documents that ElasticSearch works on, so is this just a simplified version of how things work ?
Oh my god. Are you the voice behind Webflow University? If not, it's seriously spooky how much you sound like him. :) Fantastic information. Thank you.
16:37 is really confusing, I know by This INDEX has two PRIMARY SHARDs and two REPLICAs, it probably means this way PUT /testindex { settings: { number_of_shards: 2,
It's like when you're trying to calculate purchase price on an item (that isn't free), and your local economy levies a sales tax on that item: t = tax rate (replicas) u = price (primaries) y = Purchase Price (primaries and replicas) y = u + (u * t) y = 5 + (5 * 3) y = 20
Hi, I have a question. Generally, for a document stored in the primary shard of a node, the copies of that document need to be stored only in the replicas of other nodes right? Because storing the copies in replicas of the same node doesn't make sense, because if the node goes down, the replicas are also lost.
You are correct. By default Elasticsearch will never allocate a replica to a node where there is already a copy (whether primary or replica) of that shard.
Did not like it. Does not adress the fundamental question, how do you go from your SQL/NoSQL/GraphDB to ElasticSearch. How do you sync data? Is it manual? Do you have connectors like Kafka? What is the lag/latency. What is the sync strategy? How it compares to full text search in traditional dbs? Sorry lots of kibana works and not much nutrients on the plate.

This is the best video on elastic search on youtube, other tutorials don't show or explain the concepts but this explains the foundation with clarity
Frank has a very listenable voice.
This is super clean and REALLY well explained. Thank you !
This video gave me a total understanding on what elastic search means
Informative, well-spoken, easy to understand.
This is the first time I feel like I understand how elasticsearch works. I was looking for good foundations, and I find them - very clear and great idea about the quiz !
Very clearly explained, I was a first timer on ES, understood it with one or two short rewinds. Liked the quiz with explanations!
I want to hear this guy explain everything. He is good!!!
I like the quiz section at the end. it cements one's understanding
finally understand index in elasticSearch!
Amazing! Professional! Clear and right on point.
Well done sir.
Lucky to find this. Excellent tutorial.
Liked your presentation.
Proper Introduction to all components of Elastic stack

Feedback: Very nice Video! Also, very nice presentation layout! To too loaded, not too sparse, the right balance between information and design!
Absolutely fucking incredibly well explained. OMG. Give this man a cookie!
OH MY GOD THIS WAS SO GOOD
Shard total =( no of primary shard * no of replica ) + no of primary shard
👍😎
or easily: total_shards= no_of_primary_shards * (no_of_replicas + 1)
The beginning is a bit confusing but to the end it all clears up great one !
The lecture is very good 👍📌

Useful & Comprehensive...TY!
Love it, Kane! Compact format AND lots of topics covered 👌
Clear and concise, well explained.
So I can use ElasticSearch to work with my sql server?
Brilliantly and clearly explained!
I like your voice man!
Had to come down here and appreciate your way to expaining. Super clean and the quiz at the end was fun as well. Thank you.
Thanks! Extremely helpful!
Neat! Very Helpful!
Hi team
How we can subscribe for platinum features of kibana and how we can pay for that.
very well explained
Top notch!
18:50 there are things to "node" here
he wants to avoid a pop. He can control how much air bursts out when he says a p or t or k. Or he's Dutch.
Oh my god. Are you the voice behind Webflow University? If not, it's seriously spooky how much you sound like him. :) Fantastic information. Thank you.
Wow, trying to understand elastic search and came across this video.. Well explained. +1 on the quiz at the end
Udemy intro is cool.
Thank you. But please may ask, of do my queries I elasticsearch, how to I get that data. If I want to train it for machine learning
Nice concepts !
The link to the full course takes you to a machine learning with Python course instead.
Yes, I'd like the right link too :)
informative, can you add information how does elasticsearch store such that it allow fast aggregation ?
There's a typo (Elaticsearch) in both the title and the description.
Thank you so much for letting us know. We've updated the video. We appreciate the feedback.
@@udemy Gladly. Thanks for the helpful video!
Thanks a lot
Great content
Can i get these slide ?

Yes, I'd like the right link too :)
Thanks!
Great video.
Neat tutorial thanks.
v clean video but I am worried whether this is still relevant in 2022?
what is lucene ?
great
great thanks
Just great
Introduction or Overview, not Tutorial. :(
was not expecting this from Udemy
We're sorry you didn't enjoy the video, we appreciate your feedback and will review to make sure the video titles align with the content.
title is a bit misleading
Great introduction, to elastic search and the elastic stack, however i think that the word "introduction" should not be in the title
We're so glad you liked the video, thank you for your feedback. We really appreciate it.
13:15
REST request for a web page?
GET request with a body?
What r u talkin bout?
that shit was confusing as fuck. It confuses me and i Know rest services, imagine someone who doesn't.
galat link paste kar diye hain chachaa. Elasticseach bolkar Machine learning padhaa diye!
Drop the playback speed to 0.75 and you'd think it's President Obama ! :) Excellent video BTW.
Close, but still very funny. Just needs to drop the voice about half an octave and it'd be spot on.
9:05 🖖
Thanks, but please someone who is looking for elasticsearch I think he know JSON, Restful ....

wow
I'm a simple man: I see Star Trek, I press like.
GET requests don't have a body...
cannot understand his accent properly, or he is speaking inside his mouth, really hard time understanding him.
Not beginner-friendly
that's not a tutorial
