archive node uses pruning = “nothing” mode
full node uses pruning = “default”
Snapshot server use default mode
# default: the last 100 states are kept in addition to every 500th state; pruning at 10 block intervals
# nothing: all historic states will be saved, nothing will be deleted (i.e. archiving node)
# everything: all saved states will be deleted, storing only the current state; pruning at 10 block intervals
# custom: allow pruning options to be manually specified through 'pruning-keep-recent', 'pruning-keep-every', and 'pruning-interval'
pruning = "default"
To get all the metadata from the blockchain, your node must sync in pruning nothing mode from the very start of the network. Or, there must be at least one archive node on the network for you to be able to sync data from it. As far as I know, there are no such nodes in the Akash network.
