This is my sample data structure.
package main
import (
"fmt"
)
type MicroChkpt struct {
comprtype uint32
MicroChkptInfoMap map[uint32][]byte
}
type CallChkpt struct {
FullChkptData []byte
MicroChkptMap map[uint32]*MicroChkpt
ckey uint32
comprtype uint32
AuditInProgress bool
}
var CallChkptMap map[uint32]*CallChkpt
func main() {
fmt.Println("Hello, playground")
}
So its a nested map structure,
CallChkptMap->MicroChkptMap->MicroChkptInfoMap
So i was expecting on deleting an entry from the top level map
CallChkptMap, whole underlying memory used by nested maps would be
reclaimed.
Its not happening till all entries are removed from the top level map( then
only i see memory dipping), map has ongoing insert and delete operations
and grows pretty big.
Any workarounds to reclaim the memory on deleting the specific entry please?
Should i go to the nested maps first, set them to nil and then delete the
entry from the top level map?
Appreciate all your time and inputs.
