We need
update_metadata(BagMetadata)API to be able to saveBagMetadatadirectly inside each bag file, in SQLite DB or MCAP file.update_metadata(BagMetadata) calling ones after creating storage object and second time just before destructing it.
Also added caching for
SqliteStorage::get_metadata()as follow up for Don't reopen file for every seek if we don't have to. Search directionally for the correct file #1117Note: Real saving of bag metadata in SQLite DB will be done in separate PR after Store DB schema versioning in .db3 files #1108. We need to bring this API first to unblock inform storage plugin about message-level compression #1144
