Ignore freshness when serving queries on Leader
...
It doesn't make sense to check the last leader-contact time when the
node itself is the leader. Any read, when served by the leader, is going
to be within the freshness bound.

Don't allow control over trailing logs directly, just implement a policy
that scales the number by 1.25 relative to Snapshot threshold. Without
doing this it may be that setting the snapshot threshold lower doesn't
actually affect SQLite start up times, due to log application. Perhaps
this really needs exposure at the command line, but the command line is
starting to get complicated.

Compress SQLite database in Raft snapshot
...
Before Raft truncates the log, it needs to retrieve a snapshot of the SQLite database to represent the log entries that are removed during that truncation. Raft then writes that snapshot to disk. To reduce both disk IO and disk space this change compresses that SQLite snapshot before it is written to disk, and decompresses it during a restore operation.
This change also deals with older SQLite snapshots, which were not compressed.

Use Protobuf for encoding Raft Log commands
...
This PR changes Raft Log Entry encoding from JSON to Protobuf. Furthermore, larger Raft commands (which can result from batching SQL statements, or individually long SQL statements) are compressed before encoding.
This primary reason for this change is to reduce IO load since that is one of the largest performance bottlenecks. It will also reduce internode traffic.
Legacy JSON-encoded commands are still handled by this code, so this change is backwards-compatible with previous releases in the v5 series.

read scalability for the cluster.

Broadcast Store meta via standard consensus
...
With this change the cluster metadata (arbitrary key-value data associated with each node) is now broadcast across the cluster using the standard consensus mechanism. Specifically the use case for this metadata is to allow all nodes know the HTTP API address of all other nodes, for the purpose of redirecting requests to the leader.
This change removed the need for multiplexing two logical connections
over the single Raft TCP connection, which greatly simplifies the
networking code generally.

Use single load for dump processing
...
Writing a sufficiently sophisicated parser is too much work, and unlikely to be successful soon. Instead this change simply loads the entire dump as one command, and allows the underlying SQLite support to parse it correctly. This will definitely work, but since the load goes over Raft, it may hit limits with regards to network transfer sizes. Right now any limitations in that area are unknown.
Therefore this functionality remains somewhat experimental.
