overchan - Batch update the INN overview database
overchan [
file ...]
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.
