# CAPABILITIES
#
# This section defines the capabilities of fabric network. This is a new
# concept as of v1.1.0 and should not be utilized in mixed networks with
# v1.0.x peers and orderers. Capabilities define features which must be
# present in a fabric binary for that binary to safely participate in the
# fabric network. For instance, if a new MSP type is added, newer binaries
# might recognize and validate the signatures from this type, while older
# binaries without this support would be unable to validate those
# transactions. This could lead to different versions of the fabric binaries
# having different world states. Instead, defining a capability for a channel
# informs those binaries without this capability that they must cease
# processing transactions until they have been upgraded. For v1.0.x if any
# capabilities are defined (including a map with all capabilities turned off)
# then the v1.0.x peer will deliberately crash.

# ORDERER
#
# This section defines the values to encode into a config transaction or
# genesis block for orderer related parameters.
#
################################################################################
Orderer: &OrdererDefaults
# Orderer Type: The orderer implementation to start.
# Available types are "solo" and "kafka".
OrdererType: solo
# Addresses here is a nonexhaustive list of orderers the peers and clients can
# connect to. Adding/removing nodes from this list has no impact on their
# participation in ordering.
# NOTE: In the solo case, this should be a one-item list.
Addresses:
- 127.0.0.1:7050
# Batch Timeout: The amount of time to wait before creating a batch.
BatchTimeout: 2s
# Batch Size: Controls the number of messages batched into a block.
# The orderer views messages opaquely, but typically, messages may
# be considered to be Fabric transactions. The 'batch' is the group
# of messages in the 'data' field of the block. Blocks will be a few kb
# larger than the batch size, when signatures, hashes, and other metadata
# is applied.
BatchSize:
# Max Message Count: The maximum number of messages to permit in a
# batch. No block will contain more than this number of messages.
MaxMessageCount: 500
# Absolute Max Bytes: The absolute maximum number of bytes allowed for
# the serialized messages in a batch. The maximum block size is this value
# plus the size of the associated metadata (usually a few KB depending
# upon the size of the signing identities). Any transaction larger than
# this value will be rejected by ordering. If the "kafka" OrdererType is
# selected, set 'message.max.bytes' and 'replica.fetch.max.bytes' on
# the Kafka brokers to a value that is larger than this one.
AbsoluteMaxBytes: 10 MB
# Preferred Max Bytes: The preferred maximum number of bytes allowed
# for the serialized messages in a batch. Roughly, this field may be considered
# the best effort maximum size of a batch. A batch will fill with messages
# until this size is reached (or the max message count, or batch timeout is
# exceeded). If adding a new message to the batch would cause the batch to
# exceed the preferred max bytes, then the current batch is closed and written
# to a block, and a new batch containing the new message is created. If a
# message larger than the preferred max bytes is received, then its batch
# will contain only that message. Because messages may be larger than
# preferred max bytes (up to AbsoluteMaxBytes), some batches may exceed
# the preferred max bytes, but will always contain exactly one transaction.
PreferredMaxBytes: 2 MB
# Max Channels is the maximum number of channels to allow on the ordering
# network. When set to 0, this implies no maximum number of channels.
MaxChannels: 0
Kafka:
# Brokers: A list of Kafka brokers to which the orderer connects. Edit
# this list to identify the brokers of the ordering service.
# NOTE: Use IP:port notation.
Brokers:
- kafka0:9092
- kafka1:9092
- kafka2:9092
# EtcdRaft defines configuration which must be set when the "etcdraft"
# orderertype is chosen.
EtcdRaft:
# The set of Raft replicas for this network. For the etcd/raft-based
# implementation, we expect every replica to also be an OSN. Therefore,
# a subset of the host:port items enumerated in this list should be
# replicated under the Orderer.Addresses key above.

Options:
# TickInterval is the time interval between two Node.Tick invocations.
TickInterval: 500ms
# ElectionTick is the number of Node.Tick invocations that must pass
# between elections. That is, if a follower does not receive any
# message from the leader of current term before ElectionTick has
# elapsed, it will become candidate and start an election.
# ElectionTick must be greater than HeartbeatTick.
ElectionTick: 10
# HeartbeatTick is the number of Node.Tick invocations that must

# partition
# 3. It creates a Kafka consumer (reader) for that partition.
# If any of these steps fail, they will be re-attempted every
# <ShortInterval> for a total of <ShortTotal>, and then every
# <LongInterval> for a total of <LongTotal> until they succeed.
