 ### Changing the cardinality limit for a Metric
 
-A Metric contains many Metric points which are the number of unique combinations
-of key/values recorded by an instrument. To protect the SDK from unbounded
-memory usage, there is a default limit of 2000 metric points per metric which
-will be maintained by the SDK. Once the limit is hit, any new key/value
-combination for a metric will be ignored. The SDK chooses the key/value
-combinations in the order in which they are emitted.

 individual metric, use `MetricStreamConfiguration.CardinalityLimit` setting on
