Subject: Broken image links in Wiki:Memtabl
Hello folks,
I'm tranlating the Wiki pages to Japanese now.
I found all of images in MemtableThresholds are broken:
http://wiki.apache.org/cassandra/MemtableThresholds
Can anyone fix the links?
Thanks

Hi Carlo,
As Jonathan mentions the compareWith on a column family def. is defines the
order for the columns *within* a row... In order to control the ordering of
rows you'll need to use the OrderPreservingPartitioner

That is not correct. Hinted handoffs do not count toward reaching QUORUM
counts.[1]

If you're coming into th
Sorry, was typing faster than my brain was working. I was trying to say at the higher level the request would block for the write operations in other DC's to complete. As you say.That was the ticket I was thinking of. ThanksAaron On 21 Feb, 2011,at 01:19 PM, Jonathan Ellis wrote:On Sun, Feb 20, 20
Thanks for the probing questions. Just got around to looking into this a
bit more and discovered it's not exactly what I thought. It's actually a
single multiget_slice with a fairly slow response time.
I've answered as many of the questions as I can, and have also included a
reply to Rob's state

Some of the schema operations wait to check agreement between the nodes before
proceeding.
Are there any messages in your server side logs.

AFAIK the write across the dc is sync as well. I think there I'd a ticket out
there to make them asnc, take a look at Jira.

AFAIK the MemtablePostFlusher is the TP writing sstables, if it has a queue
then there is the potential for writes to block while it waits for Memtables to
be flushed. Take a look at your Memtable settings per CF, could it be that all
the Memtables are flushing at once? There is info in the logs
My understanding..
1 read repair involves the coordinator sending a full data read to CL nodes,
resolving the differences and sending writes back. For CL one this happens
after returning, for higher CL this happens before. (my understanding of the
internals of RR are a little rough though)

The best examples I know of are in the internal cli help, and conf/casandra.yaml

Thanks Peter for the extra detail.
I thought there may have been something more mysterious going on. But it sounds
like it was just the semantics of the term "use".
Cheers

Thanks for replying, but it is not at all clear to me that redis was
ever the right solution to the problem at hand. I'm still working out
whether, in fact, Cassandra is.
Up to a fairly large scale, this particular problem needs no 'cache'
at all. It needs a write-behind persistence mechanism -- a
