[jira] [Commented] (CASSANDRA-9207) COPY FROM command does not restore all records

["Tyler Hobbs (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-9207?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14522449#comment-14522449 ] 

Tyler Hobbs commented on CASSANDRA-9207:
----------------------------------------

Yes, the precision issue affects doubles as well.  To increase the precision, in your cqlshrc file, add the following:

{noformat}
[ui]
float_precision = 16
{noformat}

(or use whatever precision you want).  On a related note, CASSANDRA-9224 should improve the default precision settings.

> 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 output:
> Processing 1000 records
> 1573 records copied.
> but when i tried to verify it by running below mentioned commands, i received only 273 records.
> 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 machine.
