Uncompressed SSTables store their checksums in a separate CRC.db file. Add this in the list of SSTable components. Since this component is used only for validation, load the component on-demand for validation tasks and delete it when all validation tasks finish. In more detail: - Make the checksum component shareable and weakly referencable. Also, add a constructor since it is no longer an aggregate. - Use a weak pointer to store a non-owning reference in the components and a shared pointer to keep the object alive while validation runs. Once validation finishes, the component should be cleaned up automatically. Signed-off-by: Nikos Dragazis <nikolaos.dragazis@scylladb.com>
