NAME

6       overchan - Batch update the INN overview database
7

SYNOPSIS

9       overchan [file ...]
10

DESCRIPTION

12       overchan reads overview data from the specified files or from standard
13       input if no files are specified, and writes that data into the INN
14       overview database.  (The file "-" means to read data from standard
15       input as well.)
16
17       Normally, overview data is stored by innd for articles as they're
18       accepted.  For performance, however, it's sometimes useful to have
19       overview data written by a separate process.  To do this, set
20       useoverchan to true in inn.conf to tell innd to not write overview data
21       directly and then add an overchan channel in newsfeeds:
22
23           overview!:*:Tc,WnteO:<pathbin>/overchan
24
25       where <pathbin> is pathbin in inn.conf.  Additionally, overchan can be
26       used to bulk-load overview data from appropriately formatted batch
27       files (such as overflow files from an overchan channel).
28
29       Each line of input should have the following format:
30
31           <token> <arrived> <expires> <data>
32
33       where <token> is the storage API token of the article in textual form
34       (surrounded by "@" characters), <arrived> is the arrival timestamp of
35       the article in seconds since epoch, <expires> is the expiration time of
36       the article in seconds since epoch or 0 if there is none, and <data> is
37       the tab-separated overview data.  Each of these fields must be
38       separated by a single space.
