Subject [jira] [Commented] (CASSANDRA-10331) Establish and implement canonical bulk reading workload(s)
Date Thu, 10 Mar 2016 07:48:40 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10331?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15188861#comment-15188861
] 

Stefania commented on CASSANDRA-10331:
--------------------------------------

In terms of establishing the canonical bulk reading workload, I suggest using the profiles
available in [this benchmark|https://github.com/stef1927/cstar_bulk_read_test] with single
clustering and row sizes of approximately 100 bytes, 1 kb and 10 kb. These correspond to the
following user profiles:

* [bulk_read_value50_cluster1.yaml|https://github.com/stef1927/cstar_bulk_read_test/blob/master/bulk_read_value50_cluster1.yaml]
* [bulk_read_value500_cluster1.yaml|https://github.com/stef1927/cstar_bulk_read_test/blob/master/bulk_read_value500_cluster1.yaml]
* [bulk_read_value5k_cluster1.yaml|https://github.com/stef1927/cstar_bulk_read_test/blob/master/bulk_read_value5k_cluster1.yaml]

Here are sample cassandra-stress commands to generate the data and read it back:

{code}
cassandra-stress user profile=bulk_read_value50_cluster1.yaml ops\(insert=1\) n=5M -rate threads=25
cassandra-stress user profile=bulk_read_value50_cluster1.yaml ops\(all_columns_tr_query=1\)
-rate threads=25
{code}

> Implement a client, use stress, or extend stress to a bulk reading workload that is indicative
of the performance we are trying to improve.
