Error handling for command execution

Variants§

§

Timeout

No response within expected time frame Is recommended to create a new client/connection in this case.

§

EncodingCommandFailed

Failed encoding TX command

§

ProtocolViolation

Received an invalid response violating the RESP protocol. Ideally this should never happen. The following causes are conceivable

  • Bug in this library (e.g. incomplete implementation of RESP protocol)
  • Redis server bug
  • Network failure. As we are using TCP, only a network stack bug or other exotic causes (e.g. bit flip) is reasonable.
  • Is recommended to create a new client/connection in this case*.
§

InvalidFuture

Future is no longer valid. This happens on fatal problems like timeouts or faulty responses, on which message<->future mapping can no longer be guaranteed Is recommended to create a new client/connection in this case.

§

TcpError

Low level network error

§

TimerError

Upstream timer/clock failure

§

CommandResponseViolation

Received an unexpected response incompatible with the command specification

§

ErrorResponse(String)

Redis error response. Inner value is the error message received.

§

MemoryFull

Memory limit reached. s. MemoryParameter Is recommended to create a new client/connection in this case.
