Subject Replications and checkpoints (again)
Date Mon, 20 Aug 2012 18:00:55 GMT
I'm still wondering about the behavior of a continuous replication and the status feedback
as far as checkpoints are concerned.

Both Futon and the _active_tasks api call indicate that the check-pointed source sequence
is lagging behind:

[{"pid":"<0.12494.0>",
"checkpointed_source_seq":990974,
"continuous":true,...,
"replication_id":"06058d20f039a2e8d990577ba65ae35e+continuous",...,
"source_seq":991539,...,
"type":"replication",
"updated_on":1345480111}]

Yet both databases show the same amount of documents:


{"db_name":"source",
"doc_count":157713,
"doc_del_count":9021,
"update_seq":991539,
"purge_seq":0,
"compact_running":false,
"disk_size":201812152456,
"data_size":null,
"instance_start_time":"1343849350087635",
"disk_format_version":5,
"committed_update_seq":991539}

{"db_name":"target",
"doc_count":157713,
"doc_del_count":9021
,"update_seq":173173,
"purge_seq":0,
"compact_running":false,
"disk_size":183233859719,
"data_size":176762791873,
"instance_start_time":"1343849350176012",
"disk_format_version":6,
"committed_update_seq":173173}

What is the expected behavior?

Why would there be no update to a checkpoint during the continuous replication?

Also, what is the reason for the data_size being null in the source database?

Thanks in advance.
