I'm aware. I did use r6gd.2xlarge in my example. :) > I do not need all the space that i3en gives me (and probably won't be able > to use it all due to memory usage, or have other issues just like you > mention), so the plan is use the big enough r6gd nodes, such as > r6gd.8xlarge, it has 1.9tb nvme, it should good enough for my needs > I feel like we have a disconnect here. :) You won't get value from the r6gd.8xlarge. You're paying for 32 cores + 256GB RAM which are mostly unusable to you unless you have a configuration where Spark is co-located with C* on the servers. It's the equivalent of using a truck to transport 2 boxes when a car will suffice. >From a dollar perspective, you're opting to pay $10,714/yr for a r6gd.8xlarge (I arbitrarily picked a standard 1-year term in West coast) versus $3839/year for an i3.2xlarge just because you want Arm but will end up using just a quarter (maybe half if I'm generous) of the compute power. It doesn't stack up for me. But YMMV. :) > (I would also add that a big chunk of the data that is not read that > frequently, so I might be ok with putting a specific set of tables on EBS) > Interestingly, how do you plan to configure that? Unless I'm mistaken, C* doesn't support tiered storage. Cheers!
