Xin Chen created FLINK-32188:
--------------------------------
Summary: Does the custom connector not support pushing down
"where" query predicates to query fields of array type？
Key: FLINK-32188
URL: https://issues.apache.org/jira/browse/FLINK-32188
Project: Flink
Issue Type: Technical Debt
Components: Table SQL / Planner
Affects Versions: 1.17.0, 1.12.2
Reporter: Xin Chen
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"？
