empiredan opened a new issue, #2069:
URL: https://github.com/apache/incubator-pegasus/issues/2069
Firstly, we create a new table in the source cluster:
```
>>> create test1 -p 8 -r 1
create app test1 succeed, waiting for app ready
test1 not ready yet, still waiting... (0/8)
test1 is ready now: (8/8)
test1 is ready now!
create app "test1" succeed
>>> ls -d
[general_info]
app_id status app_name app_type partition_count
replica_count is_stateful create_time drop_time drop_expire
envs_count
1 AVAILABLE __detect pegasus 8 1
true 2024-07-10_11:55:48 - - 0
2 AVAILABLE __stat pegasus 8 1
true 2024-07-10_11:55:48 - - 0
3 AVAILABLE temp pegasus 8 1
true 2024-07-10_11:55:48 - - 0
4 AVAILABLE xyz pegasus 8 1
true 2024-07-10_11:56:36 - - 0
5 AVAILABLE test1 pegasus 8 1
true 2024-07-10_15:32:13 - - 0
```
Then, put 2 different records into the table:
```
>>> use test1
OK
>>> set a b c
OK
app_id : 5
partition_index : 4
decree : 1
server : 10.1.128.223:8171
>>> set 1 2 3
OK
app_id : 5
partition_index : 2
decree : 1
server : 10.1.128.223:8171
>>> full_scan
partition: all
hash_key_filter_type: no_filter
sort_key_filter_type: no_filter
value_filter_type: no_filter
max_count: -1
timout_ms: 5000
detailed: false
no_value: false
"a" : "b" => "c"
"1" : "2" => "3"
2 key-value pairs got.
```
Add a new duplication for the table `test1`:
```
>>> add_dup test1 target_cluster -s -a test_dup_1 -r 3
trying to add duplication [app_name: test1, remote_cluster_name:
target_cluster, is_duplicating_checkpoint: true, remote_app_name: test_dup_1,
remote_replica_count: 3]
adding duplication succeed [app_name: test1, remote_cluster_name:
target_cluster, appid: 5, dupid: 1720596785, is_duplicating_checkpoint: true,
remote_app_name: test_dup_1, remote_replica_count: 3]
```
Check the status of the table in remote cluster, during several tens of
minutes it would keep the dead state (all of the 3 replicas are unavailable):
```
>>> ls -d
[general_info]
app_id status app_name app_type partition_count
replica_count is_stateful create_time drop_time drop_expire
envs_count
1 AVAILABLE __detect pegasus 8 3

2 AVAILABLE __stat pegasus 8 3

3 AVAILABLE temp pegasus 8 3

4 AVAILABLE xyz pegasus 8 3

5 AVAILABLE test_dup_1 pegasus 8 3

```
Check the checkpoints of table `test1` in source cluster, it is found that
there is not any checkpoint created for any replica.
```
$ ll 5.*.pegasus/data

After nearly one hour(from `15:32` to `16:27`), all of the checkpoints were
created for each replica:
