Hi all,<br>
<br>
Congrats Ariel! :)&nbsp; The sum of pages-meta-history files for the last two
 enwiki dumps are 342.7GB for the 20110115 dump and 353.5GB for the 
20110317 dump, which shows that the overall dump size grew over 2 
months.&nbsp; Seven of the individually numbered pages-meta-history files 
reduced in size while eight increased in size from 20110115 to 
20110317.&nbsp; By far the biggest decrease was the 
pages-meta-history10.xml.bz2 file which dropped from 18.7GB down to 
1.9GB.&nbsp; I think there is probably missing revisions in that page ID 
range.<br>
<br>
Here are some historical dumps sizes for comparison to show the growth of these files:<br>
<br>
enwiki-20060816-pages-meta-history.xml.7z 5.08GB<br>
enwiki-20070402-pages-meta-history.xml.7z 11.3GB (<span class="bigger">229 days since previous dump)</span><br>
enwiki-20080103-pages-meta-history.xml.7z 17.2GB (276 days since previous dump)<br>
enwiki-20100130-pages-meta-history.xml.7z 31.8GB (758 days since previous dump)<br>
enwiki-20110115-pages-meta-history[1-15].xml.7z 38.0GB (350 days since previous dump)<br>
enwiki-20110115-pages-meta-history[1-15].xml.7z (7z compression in progress)<br>
<br>
Here's a graph of this data showing the dump file size growth seems to be pretty linear:<br>
