URL: https://github.com/apache/pulsar-client-cpp/issues/442
Hi everyone, i'm running an event driven app and i use apache pulsar as
backbone. I use message's properties to exchange metadata between the services.
I noted that, when the properties exceed ~100kb the client gives
`Segmentation fault (core dumped)` (sometimes `corrupted double-linked list`
instead)
> I haven't done a proper test on the size, so take the size as a guideline
I was able to simulate the behaviour in a notebook:
```py
import pulsar
import sys
import json
# need to serialize to json nested object because client accepts properties
only
# of type (self: _pulsar.MessageBuilder, arg0: str, arg1: str)
nested_dict = json.dumps({
"foo": "bar"
})
big_dict = {
f"key{i}": nested_dict for i in range(3000)
}
print(sys.getsizeof(big_dict)) # 103856
client = pulsar.Client('pulsar://localhost:6650')
producer = client.create_producer('test-topic')
producer.send(content="test-message".encode(), properties=big_dict) #
segfault
```
Unfortunately i don't have details in the stacktrace:
```
In [4]: producer.send(content="test-message".encode(), properties=big_dict)
Segmentation fault (core dumped)
```
Pulsar client version is 3.5.0.
