Oxia

[eaba]

I want to replace the #zookeeper with #oxia, which is not working, how can I do it? I want to try Pulsar Oxia!

version: '3.8'

networks:
  pulsar-oxia:
    driver: bridge
    #ipam:
      #driver: default
      #config:
        #- subnet: 192.168.0.1/24

a short official doc for this would be super helpful and would possibly help people discovering oxia... (even those who does not read the blog or do not attend summit or its videos)

[hpvd]

@eaba did make any progress using oxia for pulsar?
if not, maybe one may look/ask/discuss in the oxia repository https://github.com/streamnative/oxia

[hpvd]

We invite everyone to try Oxia and reach out with any questions, feedback, or ideas for improvement. As an open-source project, we rely on community contributions to continue advancing the technology, and your involvement will help make Oxia more widely beneficial.

[eaba]

@hpvd I found this:

Configuration file path for metadata store. It's supported by RocksdbMetadataStore and EtcdMetadataStore FOR NOW

metadataStoreConfigPath=

[hpvd]

ok, so maybe oxia is still to fresh ;-)
on the otherhand...maybe one could simply open an issue for adding oxia support..

[tisonkun]

FYI @merlimat

[hpvd]

some news on this topic: oxia-db/oxia#346 (comment)

[merlimat]

We're preparing to add support in Pulsar 3.3

[hpvd]

wow great news! Many thanks for all your work on this stunning project!
