상태 마이그레이션 (https://github.com/klaytn/klaytn/pull/507)
불필요하고 오래된 상태/스토리지 트리를 제거하여 Klaytn 노드(Cypress) 스토리지 용량을 75%(800 GB -> 200 GB) 절약하는 새로운 JSON-RPC API
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.
Warm-up trie node cache (https://github.com/klaytn/klaytn/pull/548)
New JSON-RPC APIs to speed up the block processing by iterating the latest state trie and caching it
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.
Import blocks from String (https://github.com/klaytn/klaytn/pull/516)
Importing blocks was available only with a file. Importing blocks from a string is required for some use cases.
