Subject [jira] [Reopened] (CASSANDRA-3040) Refactor and optimize ColumnFamilyStore.files(...) and Descriptor.fromFilename and few other places responsible for work with SSTable files.
Date Fri, 19 Aug 2011 04:56:27 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-3040?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Stu Hood reopened CASSANDRA-3040:
---------------------------------


startsWith() is not a strong enough restriction: you'll still need an exact match for the
CF name at some  point (or to append the '-' separate character to your startsWith call.)

> Refactor and optimize ColumnFamilyStore.files(...) and Descriptor.fromFilename and few
other places responsible for work with SSTable files.

> ColumnFamilyStore.files(...) methods are not optimal in a sense of work they are doing
- scanning whole table directory for files and directories, but it's mission is to locate
CF specific files only.
> Descriptor.fromFilename could be refactored to use getParentFile and getName methods
instead of manual parsing of the path. Small refactorings in this sense are planed for Component
and SSTable classes.
