Batched statements two different cassandra clusters.

As far as I understand, this is impossible. There isn't a way to figure out which statement goes to which cluster. We are going to have two different clusters because the hardware config is slightly different and so is our caching strategy. A plan B could be to write to both commits to something

Tune cache MB settings per table.

It's possible to set caching to: all, keys_only, rows_only, or none .. for a given table. But we have one table which is MASSIVE and we only need the most recent 4-8 hours in memory. Anything older than that can go to disk as the queries there are very rare. … but I don't think cassandra can d

Set it up as one cluster with multiple datacenters and configure replication accordingly. -- Colin Clark +1-320-221-9531 > On Jun 1, 2014, at 2:43 PM, Kevin Burton wrote: > > As far as I understand, this is impossible. > > There isn't a way to figure out which statement goes to which clust

Re: Tune cache MB settings per table.

Not in our experience… We've been using fadvise don't need to purge pages that aren't necessary any longer. Of course YMMV based on your usage. I tend to like to control everything explicitly instead of having magic. That's worked out very well for us in the past so it would be nice to still hav

Re: Tune cache MB settings per table.

Have you been unable to achieve your SLA's using Cassandra out of the box so far? Based upon my experience, trying to tune Cassandra before the app is done and without simulating real world load patterns, you might actually be doing yourself a disservice. -- Colin 320-221-9531 > On Jun 1, 20

Re: Tune cache MB settings per table.

I think of all the areas you could spend your time, this will have the least returns. The OS will keep the most frequently used data in memory. There's no reason to require cassandra to do it. If you're curious as to what's been loaded into ram, try Al Tobey's pcstat utility. https://github.com

Good question. still migrating.. but we don't want to paint ourselves into a corner. There's an interesting line between premature optimization and painting yourself into a corner ;) Best to get it right in between both extremes. On Sun, Jun 1, 2014 at 4:30 PM, Colin wrote: > Have you been un

Your data model will most likely be the far most important component of your migration. Get that right, and the rest is easy. -- Colin Clark +1-320-221-9531 > On Jun 1, 2014, at 7:01 PM, Kevin Burton wrote: > > Good question. still migrating.. but we don't want to paint ourselves into a >
