Hello,
We have just started exploring cassandra for our project and learning
basics for designing tables to meet our queries.
We will have a table with following fields :
user_id
list_id
fname
lname
email
AND so on.
We have each user with multiple lists (csv data) so have created table as
below
Hi all,
I'm trying to test the new JSON functionalities in C* 2.2.
I'm using this example:
https://issues.apache.org/jira/browse/CASSANDRA-7970
I believe there is a typo in the CREATE TABLE statement that requires
frozen:
CREATE TABLE users (id int PRIMARY KEY,name text,addresses maptext,
want is:
INSERT INTO users JSON '{id: 123,name: jbellis,address: {home:
{street: 123 Cassandra Dr,city: Austin,zip_code: 78747,phones:
[2101234567]}}}';

Hi Michel,
My only other guess is that you actually are running Cassandra 2.1, since
thats the exact error I get if I try to execute a JSON statement against a
version earlier than 2.2.

Thanks for your help.

Hello,
I try
emain on disk until that amount of
time has passed. So you will need enough disk space for about twice the
amount of data you are expecting to have in that table.

Hello,
I try to use cassandra (3.11.5) with 8 nodes (in single datacenter). I
use one simple table, all data are inserted with 31 days TTL (the data
are never updated).
I use the TWCS strategy with:
- 'compaction_window_size': '24'
- 'compaction_window_unit': 'HOURS'
- 'max_threshold': '32'
Hi,
I want to use TWCS on a cassandra table. Documentation explain 2
concerns about it:
