asMap method

Map<String, Object> asMap(
  1. ServerStatus serverStatus
)

To be used starting with journaled engines (Only Wired Tiger, Journal Only) For inMemoryEngine the J option is ignored

We can use before 4.2 testing if the journal is active (in this case fsync doesn't make any sense, taken from mongodb Jira: "fsync means sync using a journal if present otherwise the datafiles") In 4.0 journal cannot be disabled on wiredTiger engine In 4.2 only wiredTiger can be used

Implementation

Map<String, Object> asMap(ServerStatus serverStatus) {
  var ret = <String, Object>{};
  if (w != null) {
    ret[keyW] = w;
  }
  if (wtimeout != null) {
    ret[keyWtimeout] = wtimeout!;
  }
  if (serverStatus.isPersistent) {
    if (j) {
      ret[keyJ] = j;
    }
    if (!j) {
      if (serverStatus.isJournaled) {
        ret[keyJ] = fsync;
      } else {
        ret[keyFsync] = fsync;
      }
    }
  }
  return ret;
}
