You can use the pulsar-admin cli to interact with Pulsar function's state e.g.
./bin/pulsar-admin functions querystate
That's excellent, thank you!
$ apache-pulsar-2.4.1/bin/pulsar-admin functions querystate --name
womble --key lastmsg
{
"key": "lastmsg",
"stringValue": "Hello-9",
"version": 259
}
$ apache-pulsar-2.4.1/bin/pulsar-admin functions querystate --name
womble --key global_count
{
"key": "global_count",
"numberValue": 460,
"version": 229
}
$ apache-pulsar-2.4.1/bin/pulsar-admin functions putstate --name womble
-s '{"key":"lastmsg", "stringValue":"blahblah"}'
