pub enum GooseCoordinatedOmissionMitigation {
Average,
Maximum,
Minimum,
Disabled,
}
Expand description
THIS IS AN EXPERIMENTAL FEATURE, DISABLED BY DEFAULT. Optionally mitigate the loss of data (coordinated omission) due to stalls on the upstream server.
Stalling can happen for many reasons, for example: garbage collection, a cache stampede,
even unrelated load on the same server. Without any mitigation, Goose loses
statistically relevant information as GooseUser
threads are unable to make additional requests while they are blocked by an upstream stall.
Goose mitigates this by backfilling the requests that would have been made during that time.
Backfilled requests show up in the --request-file
if enabled, though they were not actually
sent to the server.
Goose can be configured to backfill requests based on the expected
user_cadence
. The expected
cadence can be automatically calculated with any of the following configuration options.
Variants
Average
Backfill based on the average
user_cadence
for this
GooseUser
.
Maximum
Backfill based on the maximum
user_cadence
for this
GooseUser
.
Minimum
Backfill based on the minimum
user_cadence
for this
GooseUser
.
Disabled
Completely disable coordinated omission mitigation (default).
