    • newFastAppend

      default AppendFiles newFastAppend()
      Create a new append API to add files to this table and commit.

      Using this method signals to the underlying implementation that the append should not perform extra work in order to commit quickly. Fast appends are not recommended for normal writes because the fast commit may cause split planning to slow down over time.

      Implementations may not support fast appends, in which case this will return the same appender as newAppend().

      Returns:
      a new AppendFiles

      Returns:
      a new RowDelta

    • newReplacePartitions

      ReplacePartitions newReplacePartitions()
      Not recommended: Create a new replace partitions API to dynamically overwrite partitions in the table with new data.

      This is provided to implement SQL compatible with Hive table operations but is not recommended. Instead, use the overwrite API to explicitly overwrite data.

      Returns:
      a new ReplacePartitions

    • newDelete

      DeleteFiles newDelete()
      Create a new delete API to replace files in this table and commit.

      Returns an EncryptionManager to encrypt and decrypt data files.

    • locationProvider

      LocationProvider locationProvider()
      Returns a LocationProvider to provide locations for new data files.
