Hello everyone.How to configure in config? Only the table or view under the schema can be seen in the dataset. The system table is not required，Thanks in advance for your help! How to add filter conditions??

source:
    type: oracle
    config:
        host_port: '10.xxx.xx.xx4:1521'
        database: Qxxx
        username: dxxxxv
        password: Dxxxxm
sink:
    type: databub-rest
    config:
        server: '<http://localhost:8080>'

You can use:

config:
  ...
  table_pattern:
    allow:
      - regex
    deny:
      - regex
  schema_pattern:
  ...

https://datahubproject.io/docs/generated/ingestion/sources/oracle#config-details

Can you help to put the exact syntax to select only required schemas

You have to put the regex on the allow section to specify which schemas to chose.

Getting error

RROR    {datahub.entrypoints:182} - 1 validation error for PipelineConfig\n'
           'source -> allow\n'
           '  extra fields not permitted (type=value_error.extra)\n'

You should check the doco, it has details on how to use schema_pattern or table_pattern

In doc syntax not mentioned properly
