> The design of Provided Storage requires the use of an AliasMap to manage the mapping
between blocks of files on the local HDFS and ranges of files on a remote storage system.
To reduce load from the Namenode, this can be done using a pluggable external service (e.g.
AzureTable, Cassandra, Ratis). However, to aide adoption and ease of deployment, we propose
an in memory version.
> This AliasMap will be a wrapper around LevelDB (already a dependency from the Timeline
Service) and use protobuf for the key (blockpool, blockid, and genstamp) and the value (url,
offset, length, nonce). The in memory service will also have a configurable port on which
it will listen for updates from Storage Policy Satisfier (SPS) Coordinating Datanodes (C-DN).
