[jira] Commented: (COUCHDB-61) Separate storage of attachments from the main database file

["Maximillian Dornseif (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COUCHDB-61?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12672908#action_12672908 ] 

Maximillian Dornseif commented on COUCHDB-61:
---------------------------------------------

31.2 GB	database with 34175 documents. Typical Document size is 300 bytes the rest is attachments.
So we can assume about 15 MB for Documents and about 30 GB for attachments.

While accessing documents by key is decently fast view generation is extremely slow.

> At the moment all document- and attachment-data go into the same database file. It would be nice if the attachments could be saved in a different file. This would enable the use of slower and cheaper hardware for attachment storage and faster hardware for the document and index data storage.
