Configuration Description
--warehouse
The path to Paimon warehouse.
--database
The database name in Paimon catalog.
--table
The Paimon table name.
--partition-keys
The partition keys for Paimon table. If there are multiple partition keys, connect them with comma, for example "dt,hh,mm".
--primary-keys
The primary keys for Paimon table. If there are multiple primary keys, connect them with comma, for example "buyer_id,seller_id".
--computed-column
The definitions of computed columns. The argument field is from MySQL table field name.

Supported expressions are:
  • year(date-column): Extract year from a DATE, DATETIME or TIMESTAMP. Output is an INT value represent the year.
  • substring(column,beginInclusive): Get column.substring(beginInclusive). Output is a STRING.
  • substring(column,beginInclusive,endExclusive): Get column.substring(beginInclusive,endExclusive). Output is a STRING.
  • truncate(column,width): truncate column by width. Output type is same with column.
    • If the column is a STRING, truncate(column,width) will truncate the string to width characters, namely "value.substring(0, width)".
    • If the column is an INT or LONG, truncate(column,width) will truncate the number with the algorithm "v - (((v % W) + W) % W)". The "redundant" compute part is to keep the result always positive.
    • If the column is a DECIMAL, truncate(column,width) will truncate the decimal with the algorithm: let "scaled_W = decimal(W, scale(v))", then return "v - (v % scaled_W)".
