Architecture #14939
openInefficient storage of software in LDAP directory
Description
Software details are store in a specific branch, with deduplication, so that's great, but we store the full dn of these software in a node.
So every node get 2000 entries like
softwareId=000ddc3b-6c0a-4394-bb52-ad9cf012658d,ou=Software,ou=Inventories,cn=rudder-configuration
there is about twice as much data as necessary there, we could simply have the uuid and not the full DN to the software
Impact is double:- ldap directory is bigger than necessary, so its slower than necessary
- we need much more memory for everything:
when we get a node, we need to transport the thousands softwares dn, convert them to string, and manipulate it
memory impact is huge
we keep moving from softwareid that's an id to software dn that's a dn
Getting, from all the nodes, all the softwares entry, with 1000 nodes result in 1.5GB of memory, and a huge strain on GC
Graph shows big spike where all softwares are fetched, the frop is a GC

We need a clear path to get that thing better.
The problem is that we need to support for a time both encoding, since people won't be able to migrate in one go (it would be likely too long ?), and they may have dyn group based on software.
We can:
- just change dn to UUID (note that the type of softwareDn is "dn", so we will need an other attribute name in all case for uuid only; )
- change encoding and store soft in node directly.
1/ allows to have global dedup, which is good for highly similar infra with lots of identical distro/stack.
2/ allows to never have cleaning batch, which are consuming and lead to period of horrible performances
