Operators
- DPSAux: The DPSAux operator's purpose is to support primitive Java operators that desire to use the DPS toolkit Java APIs.
- DpsGetTTLWithReconnect: DpsGetTTLWithReconnect Uses the dpsGetTTL function to read key-value pairs from DPS (of any type).
- DpsPutTTLWithReconnect: DpsPutTTLWithReconnect Uses the dpsPutTTL function to write key-value pairs to Redis (of any type).
Functions
