Values are floats which can optionally be tagged with extra information. If no timestamp is provided it will be automatically generated as an epoch in millisecond precision.

A typical request to obtain the last n values
curl -k https://localhost:8000/ts/foo/last/3
[{"timestamp":1545232878575320,"data":{"value":5}},{"timestamp":1545232878575311,"data":{"value":4}},{"timestamp":1545232878575302,"data":{"value":3}}]
Finding the combined length of two time series
curl -k https://localhost:8000/ts/foo,bar/length
{"length":10}
A range query from a specific point in time
curl -k https://localhost:8000/ts/boz/since/4
[{"timestamp":5,"data":{"value":500}},{"timestamp":4,"data":{"value":400}}]
A query which filters the result based on matching tagged values and then applies an aggregation function
curl -k https://localhost:8000/ts/baz/last/5/filter/colour/equals/red/count
{"count":3}
A query across a time range
curl -k https://localhost:8000/ts/boz/range/3/5
[{"timestamp":5,"data":{"value":500}},{"timestamp":4,"data":{"value":400}},{"timestamp":3,"data":{"value":300}}]
Statistical analysis across different time series
curl -k https://localhost:8000/ts/foo,bar,baz,boz/last/5/sd
{"sd":147.6999091329942}
Other functions that can be used in above example are: sum,max,min,mean,median,count.
The delete API supports range querying across multiple time series with support for filtering
curl -k --request DELETE https://localhost:8000/ts/baz/since/0/filter/colour/contains/recurl -k https://localhost:8000/ts/baz/since/0
[{"timestamp":1545235536095244,"data":{"colour":"blue","value":2}}]
