Subject [jira] [Commented] (CASSANDRA-6962) examine shortening path length post-5202
Date Tue, 01 Apr 2014 13:50:23 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6962?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13956514#comment-13956514
] 

Yuki Morishita commented on CASSANDRA-6962:
-------------------------------------------

bq. limit them to say 10 characters each (just for the file name), truncating the name if
necessary?

We can truncate name to fit within os path limit adaptively with some calculation.

How about completely omit Keyspace name but keep ColumnFamily name and adaptively adjust(truncate)
its name?

> Did we give up on this?
> Could we clean up the redundancy a little by moving the ID into the directory name? e.g.,
ks/cf-uuid/version-generation-component.db
> I'm worried about path length, which is limited on Windows.
> Edit: to give a specific example, for KS foo Table bar we now have
> /var/lib/cassandra/flush/foo/bar-2fbb89709a6911e3b7dc4d7d4e3ca4b4/foo-bar-ka-1-Data.db
> I'm proposing
