Rudder

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

• 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
