How to filter topics in admin api ? The following call get list of topics how ever it is not able to get filtered list

let topics = admin
           .list_with_config::<TopicSpec, String>(ListRequest::default().system(self.system))
           .await?;

Code with name filter

let list_filters = ListFilters::from(topic.as_str());
     let partitions = admin
         .list_with_config::<PartitionSpec, String>(ListRequest::new(list_filters, self.system).system(self.system))
         .await?;

The value list_filters does not have any effect, the admin returns all the topics.
I had to do additional filtering as below

 let filtered_partitions = partitions.clone()
            .into_iter()
            .filter(|partition| {
                if let Some(index) = partition.name.rfind('-') {
                    let base_name = &partition.name[..index];
                    base_name == topic
                } else {
                    partition.name == topic
                }
            })
            .collect::<Vec<_>>();

Please advice if there is a better approach ?

Looks like SC partition doesn't properly filter on topic name: https://github.com/infinyon/fluvio/blob/master/crates/fluvio-sc/src/services/public_api/partition/mod.rs.

It'e straightforward to add them like: https://github.com/infinyon/fluvio/blob/master/crates/fluvio-sc/src/services/public_api/topic/fetch.rs

@sehz Fixing the code in public_api for partitions requires some more analysis, I ran into type related issues.
Can we consider public_api changes in a seperate issue and proceed to close this issue with CLI?

Sounds good

For CLI, need to add CLI E2E test, You can find them here: https://github.com/infinyon/fluvio/tree/master/tests/cli/fluvio_smoke_tests
