Apache Flink

Hi All, I was wondering whether the apache paimon connector supports `LookupSource`. Paimon is already a LSM based structure, so would be neat if queries can lookup from the paimon source itself, rather than creating another internal rocksDB/hashmap stateBackend key-value store for the same data

actually thinking more about it.. i guess its not possible because typical object stores (like S3) have too much latency to serve as a LookupSource (not to mention the cost of GET api requests  :stuck_out_tongue:
I guess i missed this point because I was always working with the local file system storage rather than cloud storage

<@U05RGQYJF9S>
paimon provides the lookup join, that uses its own LSM
<https://paimon.apache.org/docs/master/how-to/lookup-joins/#lookup-joins>

and there is also a <https://cwiki.apache.org/confluence/display/PAIMON/PIP-10%3A+Introduce+Paimon+QueryService|Query Service> in the making :smile:

haha awesome :sweat_smile:  I thought I had completely read the docs.. somehow I missed that.. thanks for the info!
