(The file \f(CW\*(C`\-\*(C'\fR means to read data from standard input as well.) .PP Normally, overview data is stored by \fBinnd\fR 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 \&\fIuseoverchan\fR to true in \fIinn.conf\fR to tell \fBinnd\fR to not write overview data directly and then add an \fBoverchan\fR channel in \&\fInewsfeeds\fR: .PP .Vb 1 \& overview!:*:Tc,WnteO:/overchan .Ve .PP where is \fIpathbin\fR in \fIinn.conf\fR. Additionally, \fBoverchan\fR can be used to bulk-load overview data from appropriately formatted batch files (such as overflow files from an \fBoverchan\fR channel). .PP Each line of input should have the following format: .PP .Vb 1 \& .Ve .PP where is the storage \s-1API\s0 token of the article in textual form (surrounded by \f(CW\*(C`@\*(C'\fR characters), is the arrival timestamp of the article in seconds since epoch, is the expiration time of the article in seconds since epoch or 0 if there is none, and is the tab-separated overview data. Each of these fields must be separated by a single space. .SH "HISTORY" .IX Header "HISTORY" Written by Rob Robertson and Rich \f(CW$alz\fR for InterNetNews.
