Are you sure about that? Sounds too high.

Wait, really? I thought it was only 10.
EL

It's 15 read-only nodes in a PolarDB cluster!

I’m pretty certain it’s 15, but I might be mixing it up with another database system.

I’m a bit confused; I thought it was either 10 or 15, but I can't recall which one.
VE

I practiced a similar question last week, and I think the answer was around 5 read-only nodes.

I think I remember reading that PolarDB can have multiple read-only nodes, but I’m not sure about the exact number.

I'm a bit confused by this question. I don't recall discussing the specifics of PolarDB cluster configurations in class. I'll have to make an educated guess on this one.
RU

Okay, I've got a strategy for this. I'll start by considering the typical use cases for read-only nodes in a PolarDB cluster, then narrow down the options based on that context.
RO

Hmm, I'm not too familiar with PolarDB clusters. I'll have to think through the potential limits and constraints to determine the maximum number of read-only nodes.
MA
Maddie

This seems like a straightforward question about PolarDB cluster configuration. I'll need to review my notes on the maximum number of read-only nodes allowed.
MA
Margarita

Wait, does this mean I can have a 'polar bear' in my PolarDB cluster? I'm going with B, just to be on the safe side.
PA
Paul

This question is making me feel a bit 'polar-ized'. I'll go with A, just to keep things simple.
IN
Inocencia

I believe it's D) 15.
TI
Tiffiny

I'll choose C) 10.
DE
Deane

I'm going with B) 5.
NA
Nakisha

I think the answer is A) 1.
EL
Ellen

Ha! I bet the developers were feeling a bit 'polar' when they set the max at 15. I'm sticking with D just to see what happens.
MA
Margurite

I'm curious too, I'll go with D and see if it's 15.
KE
Kenny

I'm going with option C, 10 read-only nodes.
ST
Stefanie
1 year ago
I think the max number of read-only nodes is 10.
MA
Macy

Wait, 15 read-only nodes? That sounds like a lot. I'm going to go with C, 10 seems more reasonable for a PolarDB cluster.
SU
Susy
1 year ago
Yeah, 15 read-only nodes does sound like a lot. I think C, 10, is the right choice.
TH
Therese
1 year ago
I agree, 10 read-only nodes does seem like a reasonable number for a PolarDB cluster.
LO
Lorita

Hmm, this seems like a tricky one. I'm guessing the answer is B, since 5 is a nice round number for a cluster, right?
AL
Alfreda

Thanks for clarifying. I'll remember that for next time.
CA
Carman

Exactly, it's not 5. It's 10 read-only nodes in a PolarDB cluster.
MA
Marleen
1 year ago
Oh, I see. That makes sense. So, it's not B) 5 after all.
KA
Kallie

I think the answer is actually C) 10, because PolarDB clusters can have up to 10 read-only nodes.
IR
Irene

I agree with Michel, C) 10 makes sense for better scalability and fault tolerance.
MI
Michel
2 years ago
I believe it's C) 10 because having more read-only nodes can improve read performance.
CA
Carin

I think the answer is A) 1.
