Subject [jira] [Commented] (CASSANDRA-9207) COPY FROM command does not restore all records
Date Wed, 29 Apr 2015 13:18:06 GMT


Gaurav commented on CASSANDRA-9207:

It is a double column. Below is the schema of table.

CREATE TABLE cron_tasks(
    type varchar,
    starts double,
    chatid varchar,
    status varchar,
    result varchar,
    reason varchar,
    PRIMARY KEY (type, starts,chatid)

If precision issue is valid for double as well, then how to resolve it.

>         Attachments: cron_task.csv
> Steps to reproduce:
> 1. run COPY TO command on keyspace A. (on my environment problem occurred on only 1 table
out of 19, only thing that io noticed is this table has >1500 records and other tables
has <1000 records)
> 2. pull the csv file and place it on machine (say machine B)where  other database resides.
(In my case this was another instance of amazon machine)
> 3. Now, run the COPY TO command on machine B. (both keyspaces, one on machine A and one
on machine B has same schema.)
> Observation:
> 1. when COPY TO command is run for table having records > 1500. Command gave following
> Processing 1000 records
> 1573 records copied.
> but when i tried to verify it by running below mentioned commands, i received only 273
> 1. SELECT COUNT(*) FROM table-name;
> 2. SELECT * FROM table-name;
> Note: please let me know if other information needs to be shared with you.
> Also, is there any other way to take the back-up of keyspace and restoring it on other
