承诺池中的最大withConcurrency值是多少

const PromisePool = require('@supercharge/promise-pool')

const details = [{name:'abc'},{name:'def'},{name:'ghi'},...............]

const { results, errors } = await PromisePool
  .withConcurrency(500)
  .for(details)
  .process(async data => {
    const user = await User.processData(data)

return user

})
