localCheckpoint
localCheckpoint.Rd
Returns a locally 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. Local checkpoints are stored in the executors using the caching subsystem and therefore they are not reliable.
Usage
localCheckpoint(x, eager = TRUE)
# S4 method for SparkDataFrame
localCheckpoint(x, eager = TRUE)
