TimestampIndex, SpentIndex, and AddressIndex have been migrated from synchronous to asynchronous operation, following the same pattern as TxIndex and other indexes using BaseIndex framework.
When enabling an index for the first time, the node will build the index in the background while remaining fully operational. Progress can be monitored via the getindexinfo RPC.
Existing nodes with indexes enabled will automatically migrate data from the old location (block index database) to new separate databases on first startup. This migration may take 20-40 minutes or longer depending on hardware specifications and index sizes. The node will log progress during migration.
Breaking changes:
SpentIndexandAddressIndexare incompatible with pruned nodes as they require access to undo data now
