I realize it is quite off topic but does anyone know of a good place to stream new series online ?

Storage is stripped across multiple volumes? 6 copies in 3 AZ needs to be understand, but what is it like have so many copies after that? Is it Read Replicas? Kindly explain.

[@Sonu-xyz123]

around 8:45 , you said it need 4 copies out of 6 to read and 3 copies to write. So what it mean ?

[@Pythoholic]

I think i mentioned 4 copies out of 6 to write the read replica you need 3 copies out of 6 to read. its basically the copies of data it needs to read, its like affirmation that if it gets 3 copies out of 6 , it will complete the read operation

[@catchroniclesbyanik]

For read operation, most of the time the writer instance and the read replicas have enough information about which segment to access to get the latest data ... So it doesn't actually require read quorum in most of the cases. Read quorum is only required when request comes to db instance after crash, because the ephemeral state has been lost

[@niteshsrivastava6504]

And the 15 replicas are created automatically or through auto scaling kinda step autoscaling? I can see a create read replica button also.

[@engr707]

ur lectures are awesome, can you tell which software you use to create your slides and graphic and are you using any libs ?, if possible so share the link it will be highly appreciated.

[@Pythoholic]

It's just ppt . Thanks a lot

[@barnalibiswas3186]

Can you explain 7:38 to 7:45

[@Pythoholic]

What it means is that aurora keeps 6 copies of your data across 3 availability zone. if you see the diagram here on the time 7:38 you can see the color code denoting the number of copies if the data. there are 2 copies each in each az

[@barnalibiswas3186]

@@Pythoholic As you have said it needs 4 copies out of 6 to write and 3 copies out of 6 to read, how do we decide that values

you dont have to it will be managed automatically

[@Pythoholic]

hey no worries… btw are you from VSV?

[@samarthgupta8782]

could you please explain 06:44 to 07:50?

[@boxitupsam792]

RDS is a database provisioning service, Database engine is the actual database u use like postgres mysql. We need 6 copies of data 1 will be master 5 others will be replicas (total 6) And that should be spread across 3 az We actually use the master to write and it replicates it across other nodes

[@niteshsrivastava6504]

For cross region disater mgmt, we can use cross region replica and promote that as primary in other region? Is the global table is replacement of cross region replica? Thanks for your efforts.

[@Pythoholic]

Sure, i will get back to you, I will collect all the doubts and make a video.

[@RK-bw8tu]

Excellent ! Thank you.

[@ranjeethnadella643]

Does 15 low-latency read replicas mean the 15 replicas are created established in closer (AZ's) to the primary DB instance?

[@Pythoholic]

Up to 15 Aurora Replicas can be distributed across the Availability Zones that a DB cluster spans within an AWS Region. it's like having the primary along with the same replications across the AZ in the region.

[@ranjeethnadella643]

Is the number of replicas automated or by default. Do AWS charges for number of replicas that we maintain?

[@Pythoholic]

As far i have read and used i have basically created them so that incase of a failure it uses the data from the replication. And thats what the documentation tells us is to create the replicas.

[@ranjeethnadella643]

@@Pythoholic I see, I thought replicas are created automatically. Thanks for clarifying

[@ayansaif6754]

what is readers endpoint?

[@chanksgaming9802]

To connect through only read the databases you dont have permission to write the data

[@devendranabar6871]

What exactly is Read Replica?

[@Pythoholic]

Amazon RDS Read Replicas enable you to create one or more read-only copies of your database instance within the same AWS Region or in a different AWS Region

[@gouravchoubey860]

@@Pythoholic Are these read replicas remains in Sync with master data?or is there any delay ?
