New JSON-RPC API to remove the unnecessary and old state/storage trie, saving the storage space for Klaytn node (Cypress) by 75% (800 GB -> 200 GB)
admin.startStateMigration()
admin.stopStateMigration()
admin.stateMigrationStatus
Klaytn node currently requires about 1TB of storage space. This size of storage was a burdensome for efficient node operation, and the state migration came here to relieve this. The state migration removes the stale state/storage trie nodes which are unnecessary for new block generation and validation. Before starting a state migration, stakingInfo is saved in a database to get stakingInfo without the staled state after the state migration.
New JSON-RPC APIs to speed up the block processing by iterating the latest state trie and caching it
debug.startWarmUp()
debug.stopWarmUp()
Until now, Klaytn node had to continuously access a database for processing a block due to uncached state trie nodes, which results in the delay in block processing. The introduced "warm-up" feature reduces this delay by iterating the last state trie and caching it.
Importing blocks was available only with a file. Importing blocks from a string is required for some use cases.
