i would respectfully disagree, what you have said is true but it really
depends on the use case.
1) do you expect to be doing updates to individual fields of an item, or
will you always update all fields at once? if you are doing separate
updates then the first is definitely easier to handle
yes, you are right, it depend on use cases.
I suggested it is a better choice not only choice. JSON will be better if
any filed change re-write whole data without reading.
I tend to use JSON more, where my data does not change or very rarely, Like
storing demoralized JSON data for analytic
Thanks again Aaron.
I think case I would not expect to see data lose. If you are still in a test
scenario can you try to reproduce the problem ? If possible can you reproduce
it with a single node ?
We will try that later this week.
We did the same exercise this week, this time we

You can consider adding -pr. When iterating through all your hosts
like this. -pr means primary range, and will do less duplicated work.

Thanks Nick.
it would be nice to pack such work-arounds together with Cassandra, and
enable it with a command line arg in the start up script, so that the
end-user has a more
smooth usage experience - we did spend some time before to debug the
ports issues, and find a trick for that.

Hi,
This support is now implemented in kundera(latest trunk branch).
Let me know, if you have any other question.

Funny you mention that... i just was hearing on #cassandra this
morning that it repairs the replica set by default. I was thinking of
repairing every 3rd node (RF=3), but running -pr seems cleaner.
Do you know if this (repairing a replica vs node) was introduced in 1.0 or 1.1?

Is there any reason why cassandra doesn't do nodetool repair out of the box
at some fixed intervals?

So in an interesting turn of events, this works on my other 4 keyspaces but
just not this 'EBonding' one which will not recognize the changes. I can
probably get around this by dropping and re-creating this keyspace since its
uptime is not too important for us.

For static column family what is the advantage in pre-defining column metadata ?
I can see ease of understanding type of values that the CF contains

something else that makes it
For the record, we just had a recurrence of this.
This time, when the node (#5) came back it didn't properly rejoin the ring.
We stopped every node and brought them back one by one to get the ring
to link up correctly.
Then, all the even nodes (#2, #4, #6) had out of data schemas.

Setting the metadata will set the validation. If you insert to a
column that is supposed to only INT values Cassandra will reject non
INT data on insert time.
Also comparator can not be changed, you only get once chance to set
the column sorting.

Thanks a very nice approach.
If every nodetool repair uses -pr does that satisfy the requirement to
run a repair before GCGraceSeconds expires? In otherwords, will we get a
correct result using -pr everywhere.
Secondly, what's the need for sleep 120?
Cheers,

I believe what may be really going on is that my schema is in a bad or corrupt
state. I also have one keyspace that I just cannot drop an existing column
family from even though it shows no errors.
So right now I was able to get 4 of my 6 keyspaces over to Network Topology
strategy.
I think

just give the cluster a chance to settle down between repairs...
there's no real need for it, just is there because.
Actually, repair could cause unreplicated data to be streamed and new
sstables to be created. New sstables could cause pending
I can confirm having seen this (no time to debug). One method of
recovery is to jump the node back into the ring with auto_bootstrap
set to false and an appropriate token set, after deleting system
tables. That assumes you're willing to have the node take a few bad
reads until you're able to
If i understand you correctly, you are only ever querying for the rows
where is_exported = false, and turning them into trues. What this means
is that eventually you will have 1 row in the secondary index table with
350K columns that you will never look at.
It seems to me you that perhaps you
All host names are resolved to IP addresses.
does the listen_address have to be hardwired to that same EXACT hostname for
lookup purposes as well?
Not sure exactly what you mean here.
I think if you only supply the host name, and your DNS is set correctly will
work.
Hope that helps.
