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.
