Bron,
Thanks for the swift reply. So if I understand this correctly, the
"archivesearchpartition-default" is named such because it's for the
archive location of Xapian search data, not because it's Xapian search
data from an Archive partition. Is that correct? In other words, this
is just another circumstance where seemingly obvious partition names
(like default-default) get us into documentation trouble. Right?
Thanks again,
-nic

Hi Nic,
The Xapian partitions are entirely separate from archive partitions.
The indexing code will find the file in the correct location if it
needs to read it.
Here's an example from one of our servers:
defaultpartition: default
defaultsearchtier: temp
partition-default: /mnt/ssd21d2/sloti21d2t40/store254/spool
tempsearchpartition-default: /tmpfs-search/sloti21d2t40
metasearchpartition-default: /mnt/ssd21d2/sloti21d2t40/store254/search
datasearchpartition-default: /mnt/i21d2search/sloti21d2t40/store254/search
archivesearchpartition-default:
/mnt/i21d2search/sloti21d2t40/store254/search-archive
archivepartition-default:
/mnt/i21d2t40/sloti21d2t40/store254/spool-archive
(clearly auto-generated!)

Bron, et al.,
We're about to set up a whole new bunch of partitions in support of
Xapian indexing, for a 2.5.10-to-3.0.4 upgrade, and then will be
introducing archive functionality, too. How do archive partitions
and Xapian partitions interact?
For example, the server currently has the following in imapd.conf:
defaultpartition: default
partition-default: /var/mailstores/default
metapartition-default: /var/imapmeta/default
partition-1: /var/mailstores/1
partition-2: /var/mailstores/2
partition-3: /var/mailstores/3
partition-4: /var/mailstores/4
...
partition-29: /var/mailstores/29
partition-30: /var/mailstores/30
partition-100: /var/mailstores/100
partition-temp: /var/mailstores/temp
...
# non-default metapartitions
metapartition-1: /var/imapmeta/1
metapartition-2: /var/imapmeta/2
metapartition-3: /var/imapmeta/3
metapartition-4: /var/imapmeta/4
...
metapartition-29: /var/imapmeta/29
metapartition-30: /var/imapmeta/30
metapartition-100: /var/imapmeta/100
metapartition-temp: /var/imapmeta/temp
Going by the documentation, which I wrote with help from you good
folk at Fastmail, the Archive partition scheme might look something
like this:
https://www.cyrusimap.org/imap/reference/admin/locations/archive-partitions.html
archivepartition-default: /var/mailarchives/default
archivepartition-1: /var/mailarchives/1
archivepartition-2: /var/mailarchives/2
archivepartition-3: /var/mailarchives/3
archiveartition-4: /var/mailarchives/4
...
archivepartition-29: /var/mailarchives/29
archivepartition-30: /var/mailarchives/30
archivepartition-100: /var/mailarchives/100
archivepartition-temp: /var/mailarchives/temp
And the Xapian partition structure to mate with this would look
something like this (again, from the docs):
https://www.cyrusimap.org/imap/developer/install-xapian.html
defaultpartition: default
partition-default: /var/mailstores/default
search_engine:xapian
search_index_headers: no
search_batchsize: 8192
defaultsearchtier: t1
1searchtier: t1
2searchtier: t1
3searchtier: t1
4searchtier: t1
...
29searchtier: t1
30searchtier: t1
100searchtier: t1
tempsearchtier: t1
...
t1searchpartition-default: /var/search/default
t1searchpartition-1: /var/search/1
t1searchpartition-2: /var/search/2
t1searchpartition-3: /var/search/3
t1searchpartition-4: /var/search/4
...
t1searchpartition-29: /var/search/29
t1searchpartition-30: /var/search/30
t1searchpartition-100: /var/search/100
t1searchpartition-temp: /var/search/temp
First question, since there's no examples to work from; Is this
Xapian layout correct?
Do I need to define & create Xapian partitions for the metadata
partitions, as is indirectly implied in Bron's original email on this
topic:
https://lists.tartarus.org/pipermail/xapian-discuss/2014-October/009112.html
Also, how do these Xapian and Archive, interact? Do I need to add a
separate Xapian partition for each Archive partition, or will the
Archive partition be treated like a child of the non-Archive
partition? (again, implied but not directly addressed in that email).
Any guidance gladly accepted, and whatever I learn will be repackaged
into more complete documentation on same.
Cheers,
-nic
