Hi, It was a great video!..Nice and clear explanation of concepts. I just have one thing to add - As per my understanding, the replicas of a given node will not hold the copy of the documents stored on that node, rather they will be stored in the replicas of other nodes in the cluster.And that's how elasticsearch will be able to recover lost data even if a node goes down.
It is a really good video series, after going through a lot of videos I found this tutorial which explains perfectly what's needed for a beginner to start learning ELK and in a really simple and to the point manner with examples which I feel are really important rather than just the theory.
please mention those links which you are referring here to watch saying "earlier videos". I am unable to find any such video in this playlist of in your channel.
I am creating 4 index using es.index method to store different sub system real time data. And only 1 node is there. What is the best method to do it correctly so it stores a large amount of data without any problem. Because for 1 run it stores total 577 attributes for 4 index.
Very well explained Amita, i have one question though..how should i maintain consistency of data between rdbms and es server?..eg: registration happened on rdbms and i want that it moves to es server..
It's a great video. I really like the way you explain from scratch. I have a question related to storing data persistently in ElasticSearch DB. Can I do that? , Are there any drawbacks in doing that?
i have one doubt in each nodes we have unique documents i.e 30k it may be unique suppose if node size is full and due to some reason node is down or we cannot read documents in that case what will happen in other nodes we may not be having same documents which present in node 1
Hi thanks for these useful series. I am new to elastic-search and I,m trying to create a cluster using nodes present in two different windows machines in a small LAN. I've created two separate nodes with the same cluster name . the first one has Master Role and the second one has Data role. but it seems both of them works independently in their own cluster. Can you please direct me to a basic tutorial? Thanks again.
_id is nothing but the location where you want to add data... you need to give this in url for more info watch part 3 ruclips.net/video/MPjily-rb1A/видео.html
Calling the type of your document 'doc' is a bit misleading. It should be employees or something similar. Anyway, great video and thanks for your effort!
bapr. you are too confusing. .. you cant understandable. this is failover. same is happening in Hadoop. block replication. kya bol Raho mam. aramsa. you know the process i know. practically dikhao. its understandable.
Finally an organised series of tutorials on Elastic Search.
Great Job!!!

3:42 mapping types are removed 6.0 onwards. One index can have only one type now.
Correct I have made video on this

A link to elasticsearch's justification: www.elastic.co/guide/en/elasticsearch/reference/7.0/removal-of-types.html
Great to find a slow and precise teaching. Please make one lecture on ELK implementation on kubernetes.
Great Video...... Mapping in ElasticSearch = Table Definition in RDBMS :)
Please carry your great work till the time I get the job.

@@TechieLifestyle Thank you very much lady :)
Its hard to record such tutorials. Thank you for your work.
true
Thanks, it is very good for beginners.

Which version of elastic search is this?
Very well explained Amita, i have one question though..how should i maintain consistency of data between rdbms and es server?..eg: registration happened on rdbms and i want that it moves to es server..
anshuman upadhyay you need export data into elastic search through scheduler by using logstash

How can we create index using a sql query?? Can u help me with this info..
i have one doubt in each nodes we have unique documents i.e 30k it may be unique suppose if node size is full and due to some reason node is down or we cannot read documents in that case what will happen in other nodes we may not be having same documents which present in node 1
This is the reason we should always have master and slave node (or more than 2 nodes). Single node cluster is not recommended for big firm.

After some research I've found that my problem is related to network.host setting in elasticsearch.yml .
Mam it seems you have change "_id" field...can you please tell me how you did so. I cant find it's method in this video lecture.
_id is nothing but the location where you want to add data... you need to give this in url for more info watch part 3 ruclips.net/video/MPjily-rb1A/видео.html
Is the mapping applicable to a particular type or to the whole index ?
Mapping is like the schema of the table in relational db. So yes it is different for each index
nice explain 100 thumps up to you
Thanks for the information
You mean JSON NOT "Jason " in the Elasticsearch Basic concept slide.
YES ITS JSON NOT JASON MY MISTAKE
Calling the type of your document 'doc' is a bit misleading. It should be employees or something similar. Anyway, great video and thanks for your effort!

Too many ads for a 10 min video ...i think i understand what not to do when you upload a video
one interface have 10 method and in class A we want to use 5 method and another 5 method in class B how we achieve
2 Abstract class should implement required methods and throw unsupported exception
Hello amita i've got some questions about this part in elasticsearch, could i send you an email to ask you ?
Sure i will check if i could help.
@@TechieLifestyle great thanks, can you pass me your email please ?
@@ChillinVibe check about in channel
Wow😍
thank you are very smart , to passing the information
Nice video
Too Many ads.
