Subject Cassandra read requests not getting timeout
Date Mon, 05 Aug 2019 06:50:02 GMT
Hi Community,

I am using Cassanadra 3.0.13 . 5 node cluster simple topology. Following
are the timeout  parameters in yaml file:

# grep timeout /etc/cassandra/conf/cassandra.yaml
cas_contention_timeout_in_ms: 1000
counter_write_request_timeout_in_ms: 5000
cross_node_timeout: false
range_request_timeout_in_ms: 10000
read_request_timeout_in_ms: 10000
request_timeout_in_ms: 10000
truncate_request_timeout_in_ms: 60000
write_request_timeout_in_ms: 2000

i'm trying a cassandra query using cqlsh and it is not getting timeout.

#time cqlsh 10.50.11.11 -e "CONSISTENCY QUORUM; select
asset_name,profile_name,job_index,active,last_valid_op,last_valid_op_ts,status,status_description,live_depth,asset_type,dest_path,source_docroot_name,source_asset_name,start_time,end_time,iptv,drm,geo,last_gc
from cdvr.jobs where model_type ='asset' AND docroot_name='vx0000030'
 LIMIT 100000 ALLOW FILTERING;"
Consistency level set to QUORUM.
(....)
(....)
(79024 rows)

real    16m30.488s
user    0m39.761s
sys     0m3.896s

The query took 16.5 minutes  to display the output. But my
read_request_timeout is 10 seconds. why the query doesn't got timeout after
10 s ??

Regards,
Renoy
