.SH DESCRIPTION
|
||
.PP
|
||
The container updater is responsible for updating container information in the account database.
|
||
It will walk the container path in the system looking for container DBs and sending updates
|
||
to the account server as needed as it goes along.
|
||
|
||
There are times when account data can not be immediately updated. This usually occurs
|
||
during failure scenarios or periods of high load. This is where an eventual consistency
|
||
window will most likely come in to play.
|
||
|
||
In practice, the consistency window is only as large as the frequency at which
|
||
the updater runs and may not even be noticed as the proxy server will route
|
||
listing requests to the first account server which responds. The server under
|
||
load may not be the one that serves subsequent listing requests – one of the other
|
||
two replicas may handle the listing.
|
||
