Data migration from MongoDB to Teradata -


we working towards migrating data mongodb teradata (dw).

we feel transformations on data necessary.

could please me answer below questions guide on developing solution migration :

  1. which best , efficient format export data mongodb load teradata(dw) considering transformations involved ? (csv/json/others)

transformations include omission of line(s) exported file, omission of fields, aggregation(sum/count) across fields etc.

  1. if developing framework etl, java choice ?

  2. we noticed ‘\n’ [newline character] part of records. hence, in csv seeing blank lines in between.

do need concerned of right line delimiter ? or can export format in regard ?

  1. we seeing records getting truncated because length of record exceeds 1024 characters.

we ‘line long’ message in vi editor. don’t have alternate editor in our system. there way around handle line truncation ?

csv not particularly well-specified - there several variants of in wild different escaping behaviors. prefer anything-but-csv.

  1. json
  2. yes
  3. this not question, ok.
  4. don't edit data vi, purely limitation of editor , not export format. transformations programmatically
