BLOCKS Reference


Convert to partitioned table


This BLOCK copies data from multiple tables separated by date (date-sharded tables) into one partitioned table

Convert to partitioned table BLOCK chart

The date-sharded tables must have their names formatted as shown below:

  • YYYY: 4-digit year. E.g. 2016
  • MM: 2-digit month (01–12). E.g. 04
  • DD: 2-digit date (01–31). E.g. 09

For example, file names like sharded_20160401 and mytable_20161231 are properly formatted with the required year, month, and date in their suffixes.
