Detail of Subtask

refactor metric/log data in path {account}/{megerd|log}/yyyy/mm/dd/{datatype}/*.csv

• {account}/log/yyyy/mm/dd/{datatype}/*.csv, store raw data directly from MO Node
• {account}/merged/yyyy/mm/dd/{datatype}/*.csv, store data from {account}/log/yyyy/mm/dd/{datatype}/*.csv which merged into one file (or a few files)

Describe implementation you've considered

we have 5 datatype: metric, statement, span, log, error

• data metric store in path {account}/*/yyyy/mm/dd/metric/*.csv
• data statement store in path {account}/*/yyyy/mm/dd/statement/*.csv
• data span, log, error store in path sys/*/yyyy/mm/dd/log/*.csv
  • these 3 type data will be store in one table (just named table log)
  • just access by sys account.
