However, in practice we've seen sometimes even a > single storage can contains large amount of blocks and the report even > exceeds the max RPC data length. It may be helpful to support sending > multiple RPC for the block report of a storage. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
