# == class: zaqar::messaging::mongodb
#
# [*uri*]
# Mongodb Connection URI. Required.
#
# [*ssl_keyfile*]
# The private keyfile used to identify the local connection against
# mongod. Default $::os_service_default
# Defaults to $::os_service_default.
#
# [*ssl_certfile*]
# The certificate file used to identify the local connection against
# mongod. (string value)
# Defaults to $::os_service_default.
#
# [*ssl_cert_reqs*]
# Specifies whether a certificate is required from the other side of
# the connection, and whether it will be validated if provided. It
# must be one of the three values ``CERT_NONE``(certificates ignored),
# ``CERT_OPTIONAL``(not required, but validated if provided), or
# ``CERT_REQUIRED``(required and validated).
# Defaults to $::os_service_default.
#
# [*ssl_ca_certs*]
# The ca_certs file contains a set of concatenated "certification
# authority" certificates, which are used to validate certificates
# passed from the other end of the connection.
# Defaults to $::os_service_default.
#
# [*database*]
# Database name. (string value). Defaults to $::os_service_default.
#
# [*max_attempts*]
# Maximum number of times to retry a failed operation. Currently only
# used for retrying a message post.
# Defaults to $::os_service_default.
#
# [*max_retry_sleep*]
# Maximum sleep interval between retries (actual sleep time increases
# linearly according to number of attempts performed).
# Defaults to $::os_service_default.
#
# [*max_retry_jitter*]
# Maximum jitter interval, to be added to the sleep interval, in order
# to decrease probability that parallel requests will retry at the
# same instant. (floating point value)
# Defaults to $::os_service_default.
#
# [*max_reconnect_attempts*]
# Maximum number of times to retry an operation that failed due to a
# primary node failover. (integer value)
# Defaults to $::os_service_default.
#
# [*reconnect_sleep*]
# Base sleep interval between attempts to reconnect after a primary
# node failover. The actual sleep time increases exponentially (power
# of 2) each time the operation is retried. (floating point value)
# Defaults to $::os_service_default.
#
# [*partitions*]
# Number of databases across which to partition message data, in order
# to reduce writer lock %. DO NOT change this setting after initial
# deployment. It MUST remain static.
# Defaults to $::os_service_default.
