    Description

      The table properties can change the behavior of wriing. e.g. the parquet table with `parquet.compression`.

      If you execute the following SQL, we will get the file with snappy compression rather than zstd.

      CREATE TABLE t (c int) STORED AS PARQUET;
// cache table metadata
SELECT * FROM t;
ALTER TABLE t SET TBLPROPERTIES('parquet.compression'='zstd');
INSERT INTO TABLE t values(1);

      So we should invalidate the table cache after alter table properties.
