Wiki applications are becoming increasingly important for
knowledge sharing between large numbers of users. To prevent
against vandalism and recover from destructive edits,
wiki applications need to maintain the revision histories of
all documents. Due to the large amounts of data and traffic,
a Wiki application needs to store the data economically
and retrieve documents efficiently. Current Wiki Data
Management Systems (WDMS) make a trade-off between
storage requirement and access time for document update
and retrieval. We introduce a new data management system,
Cosmos, to balance this trade-off. To compare Cosmos
with the other WDMSs, we use a 68GB data sample
from English Wikipedia. Our experiments show that Cosmos
uses one-fifth of the disk space when compared to MediaWiki
(Wikipedia’s backend) and performs faster than other
WDMSs at document retrieval.
