geth snapshot prune-state <state-root>

will prune historical state data with the help of the state snapshot.

All trie nodes and contract codes that do not belong to the specified
|
|
version state will be deleted from the database. After pruning, only
|
|
two version states are available: genesis and the specific one.
|
|
|
|
The default pruning target is the HEAD-127 state.

|
|
|
WARNING: It's necessary to delete the trie clean cache after the pruning.
|
|
If you specify another directory for the trie clean cache via "--cache.trie.journal"
|
|
during the use of Geth, please also specify it here for correct deletion. Otherwise
|
|
the trie clean cache with default directory will be deleted.
