checkpoint — checkpoint • SparkR

Returns a checkpointed version of this SparkDataFrame. Checkpointing can be used to truncate the logical plan, which is especially useful in iterative algorithms where the plan may grow exponentially. It will be saved to files inside the checkpoint directory set with setCheckpointDir

checkpoint(x, eager = TRUE)

# S4 method for class 'SparkDataFrame'
checkpoint(x, eager = TRUE)

x

A SparkDataFrame

eager

whether to checkpoint this SparkDataFrame immediately
