[jira] [Created] (CASSANDRA-4860) Estimated Row Cache Entry size
incorrect (always 24?)
Chris Burroughs created CASSANDRA-4860:
------------------------------------------
Summary: Estimated Row Cache Entry size incorrect (always 24?)
Key: CASSANDRA-4860
URL: https://issues.apache.org/jira/browse/CASSANDRA-4860
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.1.6
Reporter: Chris Burroughs
After running for several hours the RowCacheSize was suspicious low (ie 70 something MB) I used CASSANDRA-4859 to measure the size and number of entries on a node:
In [3]: 1560504./65021
Out[3]: 24.0
In [4]: 2149464./89561
Out[4]: 24.0
In [6]: 7216096./300785
Out[6]: 23.990877204647838
That's RowCacheSize/RowCacheNumEntires . Just to prove I don't have crazy small rows the mean size of the row *keys* in the saved cache is 67 and Compacted row mean size: 355. No jamm errors in the log
Config notes:
row_cache_provider: ConcurrentLinkedHashCacheProvider
row_cache_size_in_mb: 2048
Version info:
* C*: 1.1.6
* centos 2.6.32-220.13.1.el6.x86_64
* java 6u31 Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)

[jira] [Updated] (CASSANDRA-4860) Estimated Row Cache Entry size
incorrect (always 24?)
Posted by "Vijay (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-4860?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Vijay updated CASSANDRA-4860:
-----------------------------
Attachment: 0001-CASSANDRA-4860.patch
0001-CASSANDRA-4860-for-11.patch
Simple patch to fix the issue....
Looks like the issue is that we do Mesure instead of MeasureDeep which will actually measure the byte[] attached to the RK.
*-for-11.patch is for 1.1 and *.patch is for 1.2.
