yuruguo opened a new pull request #12242:
URL: https://github.com/apache/pulsar/pull/12242
### Motivation
Currently we can use cli `./pulsar-admin topics set-publish-rate` /
`./pulsar-admin topics set-dispatch-rate` to set message publish/dispatch rate
for a topic, but its effect is to clear the previous rate and then reset which
causes the previously rate to disappear (unless I specifically add the previous
rate when I set it again), for example:
**1st**
> ./pulsar-admin topics set-publish-rate `-b 10485760`
persistent://public/default/topic-rate-test
./pulsar-admin topics get-publish-rate
persistent://public/default/topic-rate-test
{
"publishThrottlingRateInMsg" : -1,
"publishThrottlingRateInByte" : 10485760
}
**2nd**
> ./pulsar-admin topics set-publish-rate `-m 1000`
persistent://public/default/topic-rate-test
./pulsar-admin topics get-publish-rate
persistent://public/default/topic-rate-test
{
"publishThrottlingRateInMsg" : 1000,
"publishThrottlingRateInByte" : -1
}
The purpose of this PR is to combine the previous and current rate by adding
an option `--reset-mode`, in this case, we will execute **2nd** as the result
below.
**2nd**
> ./pulsar-admin topics set-publish-rate `-m 1000` --reset-mode false
persistent://public/default/topic-rate-test
./pulsar-admin topics get-publish-rate
persistent://public/default/topic-rate-test
{
"publishThrottlingRateInMsg" : 1000,
"publishThrottlingRateInByte" : 10485760
}
