@KannarFr The indexes can be built in a background process using the approach that was used for compaction. The "compacted" ledger is essentially an "index" to the original data. The index maintains some forms of mapping between "keys" to the "offsets" to the original data. The "offset" is essentially the message-id which is referencing a ledger and an entry id. It doesn't matter if a ledger is in the bookkeeper or already offloaded to the tiered storage. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
