Frozen Rush Data Storage

Source: R/ArchiveAsyncFrozen.R
ArchiveAsyncFrozen.Rd

Freezes the Redis data base of an ArchiveAsync to a data.table::data.table(). No further points can be added to the archive but the data can be accessed and analyzed. Useful when the Redis data base is not permanently available. Use the callback bbotk.async_freeze_archive to freeze the archive after the optimization has finished.

S3 Methods

  • as.data.table(archive)
    ArchiveAsync -> data.table::data.table()
    Returns a tabular view of all performed function calls of the Objective. The x_domain column is unnested to separate columns.
