General:
# Ledger Type: The ledger type to provide to the orderer.
# Two non-production ledger types are provided for test purposes only:
# - ram: An in-memory ledger whose contents are lost on restart.
# - json: A simple file ledger that writes blocks to disk in JSON format.
# Only one production ledger type is provided:
# - file: A production file-based ledger.

# Genesis method: The method by which the genesis block for the orderer
# system channel is specified. Available options are "provisional", "file":
# - provisional: Utilizes a genesis profile, specified by GenesisProfile,
# to dynamically generate a new genesis block.
# - file: Uses the file provided by GenesisFile as the genesis block.
GenesisMethod: file
# Genesis profile: The profile to use to dynamically generate the genesis

BCCSP:

# SECTION: Kafka
#
# - This section applies to the configuration of the Kafka-based orderer, and
# its interaction with the Kafka cluster.
#
################################################################################
Kafka:
# Retry: What do if a connection to the Kafka cluster cannot be established,
# or if a metadata request to the Kafka cluster needs to be repeated.
Retry:
# When a new channel is created, or when an existing channel is reloaded
# (as part of the orderer's bootstrapping), the orderer interacts with
# the Kafka cluster in the following ways:
# 1. It creates a Kafka producer (writer) for the Kafka partition that
# corresponds to the channel.
# 2. It uses that producer to post a no-op CONNECT message to that
# partition
# 3. It creates a Kafka consumer (reader) for that partition.
# If any of these steps fails, they will be re-attempted every
# <ShortInterval> for a total of <ShortTotal>, and then every
# <LongInterval> for a total of <LongTotal> until they succeed:
# 1. Creation of Kafka producer (writer) for the channel
# 2. Creation of Kafka consumer (reader) for the channel
# 3. Posting of no-op CONNECT message to the channel
# Note that the orderer will be unable to write to or read from a
# channel until all of the steps above have been completed successfully.
ShortInterval: 5s
ShortTotal: 10m
