#
# If false, the KPL will automatically retry throttled puts. The KPL performs

# Controls the granularity of metrics that are uploaded to CloudWatch.

#
# When "shard" is selected, metrics are emitted with the stream name and
# shard id as dimensions. On top of this, the same metric is also emitted
# with only the stream name dimension, and lastly, without the stream name.
# This means for a particular metric, 2 streams with 2 shards (each) will
# produce 7 CloudWatch metrics, one for each shard, one for each stream, and
# one overall, all describing the same statistics, but at different levels of
# granularity.
#
# When "stream" is selected, per shard metrics are not uploaded; when
# "global" is selected, only the total aggregate for all streams and all

# The rate limit prevents the producer from sending data too fast to a shard.
# Such a limit is useful for reducing bandwidth and CPU cycle wastage from
# sending requests that we know are going to fail from throttling.
#
# Kinesis enforces limits on both the number of records and number of bytes
# per second. This setting applies to both.
#
# The default value of 150% is chosen to allow a single producer instance to
# completely saturate the allowance for a shard. This is an aggressive
# setting. If you prefer to reduce throttling errors rather than completely
# saturate the shard, consider reducing this setting.

# This setting provides coarse ordering among records - any two records will
# be reordered by no more than twice this amount (assuming no failures and
# retries and equal network latency).
#
# The library makes a best effort to enforce this time, but cannot guarantee
# that it will be precisely met. In general, if the CPU is not overloaded,
# the library will meet this deadline to within 10ms.
#
# Failures and retries can additionally increase the amount of time records
# spend in the KPL. If your application cannot tolerate late records, use the
# record_ttl setting to drop records that do not get transmitted in time.
#
# Setting this too low can negatively impact throughput.

# This setting is useful if your application cannot or does not wish to
# tolerate late records. Records will still incur network latency after they
# leave the KPL, so take that into consideration when choosing a value for
# this setting.
#
# If you do not wish to lose records and prefer to retry indefinitely, set
# record_ttl to a large value like INT_MAX. This has the potential to cause
# head-of-line blocking if network issues or throttling occur. You can
# respond to such situations by using the metrics reporting functions of the
# KPL. You may also set fail_if_throttled to true to prevent automatic
# retries in case of throttling.
