Overview ¶
Package raftwallogdb implements LogsDB on top of hashicorp/raft-wal.
Each sealed block (block-record + all of its logs) is a single raft-wal entry. Entry index = block.Number + 1 (offset by 1 because raft-wal reserves index 0). StoreLog fsyncs the entry to disk before returning, so SealBlock is durable on return. AddLog buffers in memory and the entry is built on SealBlock — atomicity is therefore guaranteed by the single StoreLog call.
