OVERCHAN(8)
NAME
overchan - Batch update the INN overview database
SYNOPSIS
overchan [file ...]
DESCRIPTION
overchan reads overview data from the specified files or from standard
input if no files are specified, and writes that data into the INN
overview database. (The file "-" means to read data from standard
input as well.)
- Normally, overview data is stored by innd for articles as they're
accepted. For performance, however, it's sometimes useful to have
overview data written by a separate process. To do this, set
useoverchan to true in inn.conf to tell innd to not write overview data directly and then add an overchan channel in newsfeeds: - overview!:*:Tc,WnteO:<pathbin>/overchan
- where <pathbin> is pathbin in inn.conf. Additionally, overchan can be
used to bulk-load overview data from appropriately formatted batch
files (such as overflow files from an overchan channel). - Each line of input should have the following format:
<token> <arrived> <expires> <data>- where <token> is the storage API token of the article in textual form
(surrounded by "@" characters), <arrived> is the arrival timestamp of
the article in seconds since epoch, <expires> is the expiration time of the article in seconds since epoch or 0 if there is none, and <data> is the tab-separated overview data. Each of these fields must be
separated by a single space.
