[GitHub] [incubator-paimon] hzjhjjyy opened a new issue, #1972: [Feature] Allow dynamic configuration of 'continuous.discovery-interval' using hints in Flink lookup joins.

hzjhjjyy opened a new issue, #1972:
URL: https://github.com/apache/incubator-paimon/issues/1972

   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar.
   
   
   ### Motivation
   
   In `FileStoreLookupFunction`, `CoreOptions.CONTINUOUS_DISCOVERY_INTERVAL` is used as the initial value for `refreshInterval`. For dimension tables, this time interval should be longer. On the other hand, for tables requiring real-time lookups, the interval should be kept as short as possible.
   
   ### Solution
   
   Add hints like `lookup.continuous.discovery-interval`. 
   For example: `/*+ OPTIONS('lookup.continuous.discovery-interval'='94608000') */`.
   
   ### Anything else?
   
   _No response_
   
   ### Are you willing to submit a PR?
