Modelize Transfer

npm i --save @modelize/transfer

Execution Flow

Start a new transfer with basic options: new Transfer().start()

1. onBefore(): returns resumeInfo
2. do process:
   1. onLoad(): consumes resumeInfo and reduces raw-rows
   2. for each loaded raw-row:
      1. onFilter(): consumes raw-row, return false to exclude row
      2. transform(): consumes raw-row must produce write-row
         • filtered/transformed raw-row is cleaned directly from internal memory
   3. beforeWrite(): consumes write-rows, may change the resumeInfo
      • must be run before writing, as the already written rows are cleaned directly from internal memory
   4. for each batch-to-write
      1. onWrite(): consumes batch of write-row
3. repeat process if resumeInfo not undefined now
