Subject [jira] Commented: (HBASE-1755) Putting 'Meta' table into ZooKeeper
Date Sun, 09 Aug 2009 04:53:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12741022#action_12741022
] 

Erik Holstad commented on HBASE-1755:
-------------------------------------

Did some small testing to see how a node with a lot of children would be have and what the
memory usage would be.
These numbers were produced by running a single ZooKeeper node on my laptop and will be further
tested on a bigger cluster
in the beginning  of next week, but just wanted to get some rough numbers.

Inserted 10000 children and it didn't seem to cause any issues. Approximate  memory usage
for this insert seemed to be around 6MB, so about 600B/node which seems kinda reasonable when
looking at the DataNode.java code in ZooKeeper.
