> When I customized a data source connector which assumed as image-connector, I
> found that when creating a table with ddl, I specified a field URL as an
> array type. When submitting an SQL task with Flink, I specified query this
> field as a fixed array. For example, select * from image source where
> URL=ARRAY ['/flink. jpg', '/flink_1. jpg'], but I found that it couldn't
> obtain the corresponding predicate filters at all.
> Does the custom connector not support to query fields of array type with
> "where"？
