Hi Siddharth Verma,
You can define consistency level LOCAL_ONE.
and you can applyh consistency level during statement creation.
like this -> statement.setConsistencyLevel(ConsistencyLevel.LOCAL_ONE);

Hi all users,
Currently we are using cassandra-2.1.13 but we want to upgrade *2.1.13 to
3.x* in production.
Could anyone please tell me which is the most stable *cassandra version
after 3.5*.
Thanking You!!

Varun Barala
Thanks everyone for your detailed explanation!!
We are going to upgrade from 2.1 to 3.0.8 as many people agreed that It's
safe skipping measure version 2.2.
Could anyone please tell me which *cassandra java driver* will be
compatible with 3.0.8 ?
Currently we are using *2.1.7.1 driver version*

Hi,
*How many column families are there? What is the heap size?*
You can turn off logs for statusLogger.java and gc to optimize heap usage.
Can you also monitor cpu usage and memory usage? IMO, in your case memory
is the bottle-neck.
Thanks!!

Hi,
You can create pseudo index table.
IMO, structure can be:-
CREATE TABLE IF NOT EXISTS test.user ( account_id bigint, pid bigint,
disp_name text, status int, PRIMARY KEY (account_id, pid) ) WITH
CLUSTERING ORDER BY (pid ASC);
CREATE TABLE IF NOT EXISTS test.user_index ( account_id bigint,
stability* About bugs* About performance (cluster size or DCs)*
Could you please help us to make the decision.
Thanking you!!

* Which C* version are you using?
* How many nodes are there in this cluster?
These tombstones will not be deleted if they are not older than
gc_grace_seconds.

Hi,
This is the property of table and It's not written in sstables. If you
change gc_grace, It'll get applied for all the data. Thanks!!
C* stores this info inside schema_columnfamilies

Did you change gc_grace for all column families?

Could you please explain?

Can you share result of query:-
*select gc_grace_seconds from system_schema.tables where keyspace_name =
'keyspace' and table_name = 'number_item;*

In this particular blog, they mentioned your case.

never tested it thoroughly but this should work conceptually. So
here we are taking advantage of the fact that we have volumes(data) for
the new node beforehand so we no need to bootstrap them.

I'm not sure about the use cases. But other approaches can also be
considered:-
* Every mutation will have the timestamp in the commitlog [So taking backup
of the commitlogs will give you this functionality]
* At client side, you fetch the existing writetime for those columns from
the db and also
26 matches
