of Go values and free that space manually all at once, safely. The purpose
of this functionality is to improve efficiency: manually freeing memory
before a garbage collection delays that cycle. Less frequent cycles means
the CPU cost of the garbage collector is incurred less frequently.

This functionality in this package is mostly captured in the Arena type.

Nesse caso, seria melhor ter apenas 2 servidores e usar uma porcentagem maior de seus recursos (CPU, memória, disco, largura de banda de rede, etc).

function log() {
  echo -e "$(date -u '+%Y-%m-%dT%H:%M:%S.%NZ')\t$*"
}

function retry() {
  local n=1
  local max=5
  local delay=5
  while true; do
    "$@" && break
    if [[ $n -lt $max ]]; then
      ((n++))
      log "Command failed. Attempt $n/$max:"
      sleep $delay;
    else
      log "The command has failed after $n attempts."  >&2
      return 2

## Investigação

Ao usar todas as alternativas anteriores, eu tive a chance de aprender com todas elas, aproveitar ideias e combiná-las da melhor maneira que encontrei para mim e para os times de desenvolvedores com os quais trabalhava.

Por exemplo, estava claro que idealmente ele deveria ser baseado nos _type hints_ padrões do Python.

 * point before or during the second request. It may be closed after client has started sending the
 * request body. If a request body is not retryable then the client may fail the request, making
 * client behavior non-deterministic. Add delays in the client to improve the chances that the
 * server has closed the socket before follow up requests are made.

@ExperimentalOkHttpApi
sealed interface SocketPolicy {
  /**

   */
  static void checkNo2BitCharacteristics(HashFunction function) {
    Random rand = new Random(0);
    int keyBits = 32;

    // get every one of (keyBits choose 2) deltas:
    for (int i = 0; i < keyBits; i++) {
      for (int j = 0; j < keyBits; j++) {
        if (j <= i) continue;
        int count = 0;
        int maxCount = 20; // the probability of error here is minuscule

		return fmt.Errorf("request to delete the service for bucket %s, failed with status %s", bucket, resp.Status)
	}
	return nil
}

// DeleteRecord - Removes a specific DNS entry
// No Op for Operator because operator deals on with bucket entries
func (c *OperatorDNS) DeleteRecord(record SrvRecord) error {
	return ErrNotImplemented
}

// Close closes the internal http client
func (c *OperatorDNS) Close() error {
	return nil
}

Este parâmetro recebe um `dict`, as chaves são os códigos de status para cada retorno, como por exemplo `200`, e os valores são um outro `dict` com a informação de cada um deles.

Cada um desses `dict` de retorno pode ter uma chave `model`, contendo um modelo do Pydantic, assim como o `response_model`.

O **FastAPI** pegará este modelo, gerará o esquema JSON dele e incluirá no local correto do OpenAPI.
