What is a Large Domino Application and why DAOS rocks
Thomas Hampel
4 October 2024What is a large Domino application?
To answer this question you might think of limits of the NSF datastore, such as 64Gbyte in v9 and 256GByte with Domino v10 and up.
Well, that is just what the NSF itself can store.
Thanks to DAOS you can put a lot more data into an application or mail file using attachments as they are stored outside of the NSF in a transparent way.
Recently a customer brought up an interesting example of an application they are running in production.
Database properties look like this:
I had to look twice to realize that it is cutting off "MByte" at the end, so this SINGLE instance in fact has a size of
13 TeraByte
I've seen this in test environments or playgrounds but never in the wild before.
To double check we looked at the files panel of the Admin client, which confirmed the size:
The application is working fine and is heavily used (as you can see), just backup and some maintenance tasks were a bid slow (one might guess why)
It's an app for records management and most of its size is caused by DAOS objects. In fact there are 1,9 million DAOS objects just used by this application.
Impressive and clearly a last and final reminder to customers out there who have not enabled DAOS yet.
It is not only going to save lots of storage cost, it also benefits the performance and scalability of your databases.
If you already use DAOS, take a look at the new DAOS Tuner which can optimize your environment
Large Domino Server?
Speaking of large, let me post a screenshot from a Domino server which marks the largest single Domino server (not partitioned, in prodution use) I came across so far
What is a Large Mail?
I'm sure admins out there have all seen something like this:
...a single mail with a size of 1,6 GByte, obviously containing a maultaschen recipe, which was routed perfectly fine.
While this is certainly not the world record for the largest mail, but it's one that I've seen myself and was able to take a screenshot from.
Reading about email size limits of 100 MB or even 20 MB per message as enforced at most cloud vendors sounds silly compared to what Domino was routing just fine for decades.
What about you?
Have you seen similar cases ? Do you even have examples of large Domino applications, servers, mail, etc. beyond those above?
If so, please send me a mail - preferably with (anonymized) screenshots.
