Examples

if (redux::redis_available()) {
  rand_str <- function() {
    paste(sample(letters, 20, TRUE), collapse = "")
  }
  # Suppose we have a process that exposes a heartbeat running on
  # this key:
  key <- sprintf("heartbeatr:test:%s", rand_str())

  # We can send it an interrupt over redis using:
  con <- redux::hiredis()
  heartbeatr::heartbeat_send_signal(con, key, tools::SIGINT)
}
