My app compares the last known set of files located on a series of
servers against a current snapshot for auditing purposes. Its working
really well, and I’ll open source it when its complete!
Here’s my current issue (and forgive me, I started life as a DBA and I
constantly want to revert to connection.execute.)
The tables to store my objects are organized in this way:
COMPUTER <- belongs_to / has_many => CONFIGRATIONS <= has_many /
belongs_to -> ITEMS
I have another table called SNAPSHOT that has:
table.column :computername, :string
table.column :dirname, :string
table.column :filename, :string
table.column :file_modified, :datetime
- CONFIGURATIONS and SNAPSHOT both have about 500 millions rows
- Add configurations based on the the snapshot that do not
- Delete configurations that do not exists in the current snapshot
- Update configuration that have a file_modified data newer than
the one stored in the CONIGURATION object.
- Observe all changes and log to an AUDIT table
This is pretty easy in SQL, but hard in a non set based language… Can
anyone point me in the right direction?
