[jira] [Updated] (CASSANDRA-15905) cqlsh not able to fetch all rows
when in batch mode
[ https://issues.apache.org/jira/browse/CASSANDRA-15905?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yifan Cai updated CASSANDRA-15905:
----------------------------------
Description:
The cqlsh in trunk only display the first page when running in the batch mode, i.e. using {{\-\-execute}} or {{\-\-file}} option.
It is a change of behavior. In 3.x branches, the cqlsh returns all rows.
It can be reproduced in 3 steps.
{code:java}
1. ccm create trunk -v git:trunk -n1 && ccm start
2. tools/bin/cassandra-stress write n=1k -schema keyspace="keyspace1"
3. bin/cqlsh -e "SELECT * FROM keyspace1.standard1;"
{code}
There are 1000 rows written. But the output in step 3 will only list 100 rows, which is the first page.
The related change was introduced in https://issues.apache.org/jira/browse/CASSANDRA-11534, where the cqlsh.py script no longer fetch all rows when not using tty in the print_result method.
