Minimal reproduce step

In our company's business, users will first delete data older than 30 days for a non-partitioned table, and then insert new data to update with the smaller sequence.field, however, the data will not be written because the deleted record's sequence.filed is more smaller. We must perform the full compaction after delete operation. And the full compaction is expensive for large data tables.

Is there any way to ensure that the delete operation is timely?

create table test_tb (
`req_id` STRING,
`ad_id` STRING,
`info` STRING,
`dt_seconds_asc` BIGINT
)USING paimon
TBLPROPERTIES(
  'bucket' = '1',
  'file.compression' = 'ZSTD',
  'file.format' = 'PARQUET',
  'primary-key' = 'req_id,ad_id',
  'sequence.field' = 'dt_seconds_asc');

insert into test_tb values('a', 'b', 'info-1', 100);

delete from test_tb where dt_seconds_asc < 200;

insert into test_tb values('a', 'b', 'info-1', 50);

// audit log still -D rowkind, insert data '50' is useless
select * from `test_tb$audit_log`;
OK
rowkind req_id  ad_id info  dt_seconds_asc
-D  a b info-1  100

// result is null
select * from test_tb;

What doesn't meet your expectations?

Deleted data will not be included in the sequence.field comparison

Anything else?
