nbdkit-retry-request-filter - retry single requests on error

       "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.

$filterdir/nbdkit-retry-request-filter.so
           The filter.

           Use "nbdkit --dump-config" to find the location of $filterdir.

       nbdkit-retry-request-filter - retry single requests on error

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=DELAY
           The   time   to  wait  before  retrying.   The  default  is  2  seconds.   Any  format  supported  by
           nbdkit_parse_delay(3) is allowed here.

       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.

nbdkit(1), nbdkit-filter(3), nbdkit-readahead-filter(1), nbdkit-retry-filter(1), nbdkit_parse_delay(3).
