There was a problem hiding this comment.
so unfortunately, the state history is mostly stored with SNAPPY enabled?
// stateFreezerTableConfigs configures the settings for tables in the state freezer.
var stateFreezerTableConfigs = map[string]freezerTableConfig{
stateHistoryMeta: {noSnappy: true, prunable: true},
stateHistoryAccountIndex: {noSnappy: false, prunable: true},
stateHistoryStorageIndex: {noSnappy: false, prunable: true},
stateHistoryAccountData: {noSnappy: false, prunable: true},
stateHistoryStorageData: {noSnappy: false, prunable: true},
}In this case, the partial read will be useless
