# [etcd]
# etcd is the tool Featurebase uses for node-to-node, intra-cluster 
# communication.  etcd is embedded in the featurebase cluster rather than 
# running as a separate instance.
# It's important to configure this correctly for your network and nodes, and 
# that it is consistent across all nodes.
#
# The easiest setup can be used when all nodes can reach all other nodes via a 
# local subnet:
#     listen-peer-address = advertise-peer-address
#                         = (what's in the initial-cluster-list)
#                         = the nodes ip address (which can be reached by every 
#                           other node
#     (localhost:10401 would not work for this, as each node can't reach that)
#
# If each node is separated by a proxy, or must be reached via url / dns, you 
# will need to use a more complicated setup:
#    listen-peer-address    = the nodes local ip address
#                             (specific ip, localhost, or 0.0.0.0 for all 
#                             local ip's)
#    advertise-peer-address = the nodes ip address, reachable by all other nodes
#                             (This address should also be included in 
#                             initital-cluster-list)
# in this case, you specify a different url/ip for listen-peer and 
# advertise-peer. E.g. you specify 0.0.0.0 for listen, or (like in their case) 
# you use a url for advertise. In each of these cases, you should set listen 
# to the local ip, and you set advertise = to how each other node connects to 
# this node, and you also use this same address in the initial cluster.
# The key here is that initial-cluster has to include the same node name and 
# advertise-peer address as the node it's on (edited)



# for additional assistance, and for help with config issues, 
# see https://etcd.io/docs/v3.5/faq/ cluster-url - URL of existing cluster 
# that a new node should join when adding nodes to cluster.
#
# cluster-url = "http://localhost:10401"

# No PostgreSQL endpoint will be exposed unless a bind address is specified.
# Requires Molecula v3.0 or newer.

# The PostgreSQL endpoint has support for a connection limit.
# This is generally not necessary, so it is disabled by default.
#
# connection-limit = 10000



# PostgreSQL Max Startup Packet Size - By default, the postgres endpoint
# uses an 8 MiB limit on incoming PostgreSQL startup packets. This should
# typically be sufficient, but may be exceeded if a client sends an unusually 
# large amount of configuration data. Oversized startup packets are typically 
# caused by connecting with a different protocol, e.g. HTTP.
#
# max-startup-size = 10000000



# PostgreSQL Timeouts
# In order to detect stalled clients, the PostgreSQL endpoint has connection 
# read and write timeouts. There is also a startup timeout, which is used for 
# connection setup. The read timeout does not impact idle connections. Idle 
# connections will only be closed by the server if TCP keepalive reports a 
# break in the connection. TCP keepalives use the default configuration
# provided by the host.
# Caution: Due to a limitation of the PostgreSQL wire protocol,
# raising the write timeout may delay the shutdown of a featurebase node.
