创建了一个物化视图，如下：
CREATE MATERIALIZED VIEW agg_active_vendor
COMMENT “MATERIALIZED_VIEW”
DISTRIBUTED BY HASH(vendor_id,vendor_name) BUCKETS 1
REFRESH ASYNC START(“2023-09-06 11:55:00”) EVERY(INTERVAL 5 MINUTE)
PROPERTIES (
“replication_num” = “1”,
“replicated_storage” = “true”,
“force_external_table_query_rewrite” = “true”,
“storage_medium” = “HDD”
)
AS
SELECT vendor_id,vendor_name,count(1)
FROM adx_report_active
GROUP BY vendor_id, vendor_name;
但是在执行
explain
SELECT vendor_id,vendor_name,count(1)
FROM adx_report_active
GROUP BY vendor_id, vendor_name;
查看此次查询并没有命中物化视图，请教一下是什么原因：
