Tellier Benoit commented on JAMES-2555:
---------------------------------------

@mbaechler is not happy with the webadmin ReIndexing API cf https://github.com/linagora/james-project/pull/1948#discussion_r236977988


Proposal that emerged from PR comments:


{code:java}
#ReIndex all mailboxes
POST /mailboxes?task=reIndex

# A single mailbox
POST /mailboxes/id?task=reIndex

# A single message in a mailbox
POST /mailboxes/id/messages/mId?task=reIndex

# A single message
POST /messages/id/?task=reIndex

# A single user
POST /mailboxes?task=reIndex&user=bob@domain.tld
{code}

> Reported internally:
> {code:java}
> Doing a reindex via the CLI on a mailbox which contains ~24000 mails does not work.
>  -  heap out of memory issue
> Heap increased, then:
>  -  cassandra timeout when increasing heap
> Timeout increased, then:
>  -  heap out of memory issue
> Heap increased, then:
>  -  GC overhead limit exceeded
> {code}
> In ReIndexerImpl instead of doing a FULL read to reindex the all mailbox (AND all of the related data) we should rather do a first metadata query to load uids then perform subsequent single reads.
> That is the root issue: trying to load 11 Go of mails in memory.
> Furthermore, a simple error should not trigger the end of a ReIndexing.
