[Bug]: Mixed-Format Unkeyed Table will read the full amount of data even if configured with 'scan.startup.mode'='latest'

[lklhdu]

What happened?

When I read an unkeyed amoro table of type mixed-format through Flink, I found that even with the 'scan.startup.mode'='latest' configuration item configured, the full amount of data is read, which is not a situation that meets expectations.

What table formats are you seeing the problem on?

Mixed-Iceberg, Mixed-Hive

What engines are you seeing the problem on?

Flink

How to reproduce

1. Create an unkeyed table of type mixed-format

   create table test_db.test_table (
   id int,
   name string, 
   age int
   ) using mixed_hive;

2. Write several initial data

   insert into test_db.test_table values (1,'name1',10);
   insert into test_db.test_table values (2,'name2',10);

3. Set 'scan.startup.mode' to latest to start reading data from the current latest snapshot

   select * from test_db.test_table
   /*+ OPTIONS('streaming'='true','arctic.read.mode'='file','source.parallelism' = '1','table.format'='MIXED_HIVE','scan.startup.mode'='latest') */;

   But it will read the full amount of data, not as expected.
