[PR] [feature] Support importing MySQL geographic data types and PostgreSQL array data types [doris-kafka-connector]
vinlee19 opened a new pull request, #25:
URL: https://github.com/apache/doris-kafka-connector/pull/25
1. The Geometry data type in MySQL will be converted to a JSON-formatted string. For example, the data `ST_GeomFromText('POINT(3 1)') ` will be converted to a JSON string:
```
{"coordinates":[3,1],"type":"Point","srid":0}
```
2. Support importing array data types in PostgreSQL.
