NAME
nbdkit-retry-request-filter - retry single requests on error
SYNOPSIS
nbdkit
--filter=retry-request PLUGIN
[retry-request-retries=N] [retry-request-delay=N]
[retry-request-open=false]
DESCRIPTION
"nbdkit-retry-request-filter" is a filter for nbdkit that transparently retries single requests if they fail. This is useful for plugins that are not completely reliable or have random behaviour. For example nbdkit-curl-plugin(1) might behave this way if pointed at a load balancer which sometimes redirects to a web server that is not responsive.
An alternative filter with different trade-offs is nbdkit-retry-filter(1). That filter is more heavyweight because it always reopens the whole plugin connection on failure.
PARAMETERS
retry-request-retries=N
The number of times any single request will be retried before we give up and fail the operation. The default is 2.
retry-request-delay=N
The number of seconds to wait before retrying. The default is 2 seconds.
retry-request-open=false
If set to false, do not retry opening the plugin. The default is to treat plugin open in the same way as other requests.
FILES
$filterdir/nbdkit-retry-request-filter.so
