List, delete, and prune pin versions — pin

pin_versions() lists available versions a pin.
pin_versions_prune() deletes old versions.
pin_version_delete() deletes a single version.

Usage

pin_versions(board, name, ...)

pin_version_delete(board, name, version, ...)

pin_versions_prune(board, name, n = NULL, days = NULL, ...)

Arguments

board, name: A pair of board and pin name. For modern boards, use board |> pin_versions(name). For backward compatibility with the legacy API, you can also use pin_versions(name) or pin_version(name, board).
...: Additional arguments passed on to methods for a specific board.
version: Version identifier.
n, days: Pick one of n or days to choose how many versions to keep. n = 3 will keep the last three versions, days = 14 will keep all the versions created in the 14 days. Regardless of what values you set, pin_versions_prune() will never delete the most recent version.

Value

A data frame with at least a version column. Some boards may provided additional data.

Examples

board <- board_temp(versioned = TRUE)

board |> pin_write(data.frame(x = 1:5), name = "df")
#> Guessing `type = 'parquet'`
#> Creating new version '20260802T194606Z-b3722'
#> Writing to pin 'df'
board |> pin_write(data.frame(x = 2:6), name = "df")
#> Guessing `type = 'parquet'`
#> Creating new version '20260802T194606Z-7e49b'
#> Writing to pin 'df'
board |> pin_write(data.frame(x = 3:7), name = "df")
#> Guessing `type = 'parquet'`
#> Creating new version '20260802T194606Z-3bf53'
#> Writing to pin 'df'

# pin_read() returns the latest version by default
board |> pin_read("df")
#> # A data frame: 5 × 1
#>       x
#>   <int>
#> 1     1
#> 2     2
#> 3     3
#> 4     4
#> 5     5

# but you can return earlier versions if needed
board |> pin_versions("df")
#> # A tibble: 3 × 3
#>   version                created             hash 
#>   <chr>                  <dttm>              <chr>
#> 1 20260802T194606Z-3bf53 2026-08-02 19:46:06 3bf53
#> 2 20260802T194606Z-7e49b 2026-08-02 19:46:06 7e49b
#> 3 20260802T194606Z-b3722 2026-08-02 19:46:06 b3722

ver <- pin_versions(board, "df")$version[[1]]
board |> pin_read("df", version = ver)
#> # A data frame: 5 × 1
#>       x
#>   <int>
#> 1     3
#> 2     4
#> 3     5
#> 4     6
#> 5     7

# delete all versions created more than 30 days ago
board |> pin_versions_prune("df", days = 30)
#> No old versions to delete
