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