[jira] Commented: (COUCHDB-956) Return all _seq values as strings not integers

["Adam Kocoloski (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COUCHDB-956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12933441#action_12933441 ] 

Adam Kocoloski commented on COUCHDB-956:
----------------------------------------

The replicator sorts sequence values from the rows it has processed in the _changes feed to ensure that it always checkpoints at the highest one possible.  Sorting them as strings results in the replicator skipping checkpoints after it reaches a sequence with a number of leading 9s.

> Some fields are returned as strings in db_info and other places to protect against numeric overflow;
> {"db_name":"db","doc_count":0,"doc_del_count":0,"update_seq":0,"purge_seq":0,"compact_running":false,"disk_size":79,"instance_start_time":"1290088043619158","disk_format_version":5,"committed_update_seq":0}
> here, instance_start_time is protected but, more critically, update_seq is not.
> If update_seq were to be wrapped due to precision issues, what breaks?
