RanListManager

• An optimization suggestion (APPROVED) - instead managing a list of []*NbIdentity, manage a map of [string]*NbIdentity, where key is inventoryName and value is the nbIdentity.

type RanListManager struct {
	rnibDataService services.RNibDataService
	mux sync.Mutex
	nbIdentityListnbIdentityMap map[string]*NbIdentity
}

type IRanListManager interface {
	InitNbIdentityListInitNbIdentityMap() error
	AddNbIdentity(nodeType entities.Node_Type, nbIdentity *entities.NbIdentity) error
	UpdateNbIdentityUpdateNbIdentityConnectionStatus(nodeType entities.Node_Type, ranName string, nbIdentityconnectionStatus *entities.NbIdentityConnectionStatus) error
	DeleteNbIdentityRemoveNbIdentity(nodeType entities.Node_Type, nbIdentity *entities.NbIdentityranName string) error
	GetNbIdentityList() []*entities.NbIdentity
}

GetNbIdentityList

• Returns the in-memory nbIdentity list (iterate map values and append to a []*NbIdentity slice)
• Affected flows: Get Nodeb Ids REST API & Red Button

Get Nodeb States REST API

• Change url from /v1/nodeb/ids to /v1/nodeb/states
• Add ConnectionStatus property to NbIdentity proto (already pushed)
• Get nbIdentity list from memory instead of DB

Image Added

Red Button REST API

• Similarly, get nbIdentity list from memory instead of DB

Image Added- getListNodebIds calls:
- delete_all_request_handler
- get_nodeb_id_list_request_handler
- every getListNodebIds call will be replaced by an in-memory call - ranListManager.GetNbIdentityList()

RnibWriter Changes

Modify

We shall modify the following methods:

• SaveNodeb(nbIdentity *entities.NbIdentity, nodebInfo *entities.NodebInfo) error
  • Change signature to: SaveNodeb(nbIdentity *entities.NbIdentity, nodebInfo *entities.NodebInfo) error
  • Modify implementation:
    • Remove UNKNOWN nodeType handling (reason: setup is now deterministic)
    • Remove save nbIdentity code - it would be called sequentially externally
      
      
• RemoveEnb(nodebInfo *entities.NodebInfo) error

Optimization suggestions

• Instead of managing a SET in REDIS DB, manage a HASH (read more: https://redis.io/topics/data-types | https://redis.io/topics/memory-optimization)
