<body><div style="font-family:Arial;">Hi Nic,<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">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.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">Here's an example from one of our servers:<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">defaultpartition: default<br></div>
<div style="font-family:Arial;">defaultsearchtier: temp<br></div>
<div style="font-family:Arial;">partition-default: /mnt/ssd21d2/sloti21d2t40/store254/spool<br></div>
<div style="font-family:Arial;">tempsearchpartition-default: /tmpfs-search/sloti21d2t40<br></div>
<div style="font-family:Arial;">metasearchpartition-default: /mnt/ssd21d2/sloti21d2t40/store254/search<br></div>
<div style="font-family:Arial;">datasearchpartition-default: /mnt/i21d2search/sloti21d2t40/store254/search<br></div>
<div style="font-family:Arial;">archivesearchpartition-default: /mnt/i21d2search/sloti21d2t40/store254/search-archive<br></div>
<div style="font-family:Arial;">archivepartition-default: /mnt/i21d2t40/sloti21d2t40/store254/spool-archive<br></div>
<div style="font-family:Arial;"><br></div>

<div style="font-family:Arial;"> 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?<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> For example, the server currently has the following in imapd.conf:<br></div>

<br></pre></blockquote><div style="font-family:Arial;">Going by the documentation, which I wrote with help from you good
folk at Fastmail, the
Archive partition scheme might look something like this:<br></div>
<div style="font-family:Arial;"> <a href="https://www.cyrusimap.org/imap/reference/admin/locations/archive-partitions.html">https://www.cyrusimap.org/imap/reference/admin/locations/archive-partitions.html</a><br></div>
<div style="font-family:Arial;"> <br></div>
<blockquote><pre>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
<br></pre></blockquote><div style="font-family:Arial;">And the Xapian partition structure to mate with this would look
something like this (again, from the docs):<br></div>
<div style="font-family:Arial;"> <a href="https://www.cyrusimap.org/imap/developer/install-xapian.html">https://www.cyrusimap.org/imap/developer/install-xapian.html</a><br></div>

Xapian layout correct? <br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> Do I need to define & create Xapian partitions for the metadata
partitions, as is indirectly implied in Bron's original email on
this topic:<br></div>
<div style="font-family:Arial;"> <a href="https://lists.tartarus.org/pipermail/xapian-discuss/2014-October/009112.html">https://lists.tartarus.org/pipermail/xapian-discuss/2014-October/009112.html</a><br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> 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).<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> Any guidance gladly accepted, and whatever I learn will be
repackaged into more complete documentation on same.<br></div>
<div style="font-family:Arial;"> <br></div>
<div style="font-family:Arial;"> Cheers,<br></div>
