Feature/rate limit v2

[Tsuyoshi-Ishikawa]

Implementation Details

Enable to set multiple rate limits to a tx allow rule

// Before
export const getTxAllowList = (): Array<TransactionAllow> => {
  return [
    {
      fromList: ['*'],
      toList: ['*'],
      rateLimit: rateLimitA,
    },
  ];
};


// After
export const getTxAllowList = (): Array<TransactionAllow> => {
  return [
    {
      fromList: ['*'],
      toList: ['*'],
      rateLimits: [rateLimitA],
    },
  ];
};

Enable to set RDB(MySQL) as a new datastore

You can set RDB(MySQL) as a new datastore by setting process.env.RDB_URI.

Modify transaction rate limit logic

I have set the tx rate limit specification as follows.

• minimize datastore access
• never allow more transactions than the transaction rate limit to request verse.
