API

The substreams-sink-redis also exposes an API that can be used to interact with the Redis KV store.

/GET

Uses the Redis GET command to retrieve the value of a key.

Params

• key: The key to retrieve the value from.

Example

/GET?key=foo

/INFO

Uses the Redis INFO command to retrieve information and statistics about the Redis server.

/TS/RANGE

Uses the Redis TS.RANGE command to retrieve a range of values from a timeseries.

Params

• key: The key to retrieve the timeseries from.
• fromTimestamp: Get samples starting from this timestamp (default is -).
• toTimestamp: Get samples up to this timestamp (default is +).
• aggregationType: The aggregation type to use. Can be one of AVG, SUM, MIN, MAX, RANGE, COUNT, FIRST, LAST, STD.P, STD.S, VAR.P, VAR.S, RATE, RATE.SECOND, RATE.MINUTE, RATE.HOUR, RATE.DAY (default is SUM).
• bucketDuration: The bucket duration in milliseconds (default is 1).

Example

/TS/RANGE?key=TIMESERIES&fromTimestamp=1602618850000&toTimestamp=1602618426000&aggregationType=SUM&bucketDuration=123

[
    {
        "timestamp": 1602618850000,
        "value": 1086139
    },
    {
        "timestamp": 1602618850123,
        "value": 1078466
    },
    {
        "timestamp": 1602618850246,
        "value": 1139608
    },
    ...
]

/TS/INFO

Uses the Redis TS.INFO command to retrieve information and statistics about the Redis TimeSeries.

Params

• key: The key to retrieve the timeseries info from.

Example

/TS/INFO?key=foo
