      max: '2023-12-31',
      format: 'yyyy-MM-dd',
      // `step` bundles interval + unit (supply both or neither). Optional at day
      // precision or coarser; required when the format is sub-day (e.g. hours).

Properties ​

formatstringformatstrformatStringFormatstringFormat*stringrequired#
Date format for partition values.

Uses Java SimpleDateFormat patterns.

maxstringmaxstrmaxStringMaxstringMax*stringrequired#
End date for the partition range (inclusive).

Can be either:

  • Fixed date in the format specified by format property
  • Relative date using NOW syntax

Same format constraints as min.

minstringminstrminStringMinstringMin*stringrequired#
Start date for the partition range (inclusive).

Can be either:

  • Fixed date in the format specified by format property (e.g., '2020-01-01' for format 'yyyy-MM-dd')
  • Relative date using NOW syntax (e.g., 'NOW', 'NOW-3YEARS', 'NOW+1MONTH')

Interval step (`interval` + `intervalUnit`) between partition values.
notes · default

The two are supplied together, so a partial step cannot be expressed. Required when format carries sub-day precision — a field finer than a day, such as hours or AM/PM; at day or coarser precision Athena defaults the step, so it may be omitted.

Default: Athena's default step for the format's precision; required when format is sub-day precision
