[jira] [Created] (CASSANDRA-3329) make HSHA the default Thrift
server
make HSHA the default Thrift server
-----------------------------------
Key: CASSANDRA-3329
URL: https://issues.apache.org/jira/browse/CASSANDRA-3329
Project: Cassandra
Issue Type: Improvement
Components: API
Reporter: Jonathan Ellis
Assignee: Jonathan Ellis
Priority: Minor
Fix For: 1.0.0
HSHA has been an option since 0.8.3 (CASSANDRA-1405) and has been stable. Besides making possible lots of unpooled connections such as are common in some environments (*cough* PHP), we've seen EC2 in particular have trouble with lots of threads (CASSANDRA-2170).

[jira] [Updated] (CASSANDRA-3329) make HSHA the default Thrift
server
Posted by "Jonathan Ellis (Updated) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-3329?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jonathan Ellis updated CASSANDRA-3329:
--------------------------------------
Attachment: 3329.txt
testing on Windows, I get 17-18k rows/s with hsha instead of 21-24 with sync. So I'll leave the default as sync.
patch updates comments and defaults hsha thread pool to # of cpu cores.

[jira] [Commented] (CASSANDRA-3329) make HSHA the default Thrift

Brandon Williams commented on CASSANDRA-3329:
---------------------------------------------
It looks like defaulting to the number of cores for hsha isn't quite adequate - I get about 20% less throughput on 4 cores with this patch than if I set it explicitly to 16.

Brandon Williams commented on CASSANDRA-3329:
---------------------------------------------
Looks like it defaults to hsha if the config doesn't specify, but +1 otherwise.
