我想对数据库的存储规则进行动态控制。我的意思是它应该检查数据库节点以允许读取或写入。但我找不到办法。例如

match /files/{fileKey} {
  allow read: // here will check db to get result of allowRead 
  allow write: // here will check db to get result allowWrite
}

D b：

files: {
  fileKey1: {
    allowRead: true,
    allowWrite: false
},
  fileKey2: {
    allowRead: true,
    allowWrite: true
}
