Browse source 
I realized that "TTLs are applied" is ambiguous. Metrics don't only
expire on receiving a sample, so mention that this is about the

"ms", "s", "m", "h". For example, `ttl: 1m20s`. `0` value is used to indicate
metrics that do not expire.
TTLs are applied to each mapped metric name/labels combination whenever
new samples are received. This means that you cannot immediately expire a
metric only by changing the mapping configuration. At least one sample must
be received for updated mappings to take effect.
