To Reproduce

./risedev d and connect with psql

CREATE source s1 (seq_id bigint, user_id bigint,
  user_name varchar)
WITH (
     connector = 'datagen',
     fields.seq_id.kind = 'sequence',
     fields.seq_id.start = '1',
     fields.seq_id.end = '10000000',
     fields.user_id.kind = 'random',
     fields.user_id.min = '1',
     fields.user_id.max = '10000000',
     fields.user_name.kind = 'random',
     fields.user_name.length = '10',
     datagen.rows.per.second = '100000'
 ) format plain encode json;
set sink_decouple=true;
create sink sink from s1 with (connector = 'blackhole');

It panics soon with

thread 'risingwave-compaction' panicked at src/storage/src/hummock/compactor/shared_buffer_compact.rs:405:13:
assertion failed: epoch < earliest_range_delete_which_can_see_key &&\n    earliest_range_delete_which_can_see_key < pivot_last_delete_epoch

After disable merge imm, it panics with

assertion failed: iter_key.epoch < earliest_range_delete_which_can_see_iter_key &&\n    earliest_range_delete_which_can_see_iter_key < user_key_last_delete_epoch

After change both debug_assert condition from < to <=, it panics with
