2020/09/14 - Amazon Managed Blockchain - 2 updated api methods
Changes Introducing support for Hyperledger Fabric 1.4. When using framework version 1.4, the state database may optionally be specified when creating peer nodes (defaults to CouchDB).
{'NodeConfiguration': {'StateDB': 'LevelDB | CouchDB'}}
Creates a peer node in a member.

string
[REQUIRED]
A unique, case-sensitive identifier that you provide to ensure the idempotency of the operation. An idempotent operation completes no more than one time. This identifier is required only if you make a service request directly using an HTTP client. It is generated automatically if you use an AWS SDK or the AWS CLI.
This field is autopopulated if not provided.
string
[REQUIRED]
The unique identifier of the network in which this node runs.
string
[REQUIRED]
The unique identifier of the member that owns this node.
dict
[REQUIRED]
The properties of a node configuration.
InstanceType (string) -- [REQUIRED]
The Amazon Managed Blockchain instance type for the node.
AvailabilityZone (string) -- [REQUIRED]
The Availability Zone in which the node exists.
LogPublishingConfiguration (dict) --
Configuration properties for logging events associated with a peer node owned by a member in a Managed Blockchain network.
Fabric (dict) --
Configuration properties for logging events associated with a node that is owned by a member of a Managed Blockchain network using the Hyperledger Fabric framework.
ChaincodeLogs (dict) --
Configuration properties for logging events associated with chaincode execution on a peer node. Chaincode logs contain the results of instantiating, invoking, and querying the chaincode. A peer can run multiple instances of chaincode. When enabled, a log stream is created for all chaincodes, with an individual log stream for each chaincode.
Cloudwatch (dict) --
Parameters for publishing logs to Amazon CloudWatch Logs.
Enabled (boolean) --
Indicates whether logging is enabled.
PeerLogs (dict) --
Configuration properties for a peer node log. Peer node logs contain messages generated when your client submits transaction proposals to peer nodes, requests to join channels, enrolls an admin peer, and lists the chaincode instances on a peer node.
Cloudwatch (dict) --
Parameters for publishing logs to Amazon CloudWatch Logs.
Enabled (boolean) --
Indicates whether logging is enabled.
StateDB (string) --
The state database that the node uses. Values are LevelDB or CouchDB . When using an Amazon Managed Blockchain network with Hyperledger Fabric version 1.4 or later, the default is CouchDB .

(dict) --
NodeId (string) --
The unique identifier of the node.
{'Node': {'StateDB': 'LevelDB | CouchDB'}}
Returns detailed information about a peer node.
