read_files

Read a dataset from a set of files

Read files into a dataset, optionally processing them in parallel.

 
read_files( 
  files, 
  reader, 
  ..., 
  parallel_files = 1, 
  parallel_interleave = 1, 
  num_shards = NULL, 
  shard_index = NULL 
)

Arguments	Description
files	List of filenames or glob pattern for files (e.g. “*.csv”)
reader	Function that maps a file into a dataset (e.g. `text_line_dataset()` or `tfrecord_dataset()`).
…	Additional arguments to pass to `reader` function
parallel_files	An integer, number of files to process in parallel
parallel_interleave	An integer, number of consecutive records to produce from each file before cycling to another file.
num_shards	An integer representing the number of shards operating in parallel.
shard_index	An integer, representing the worker index. Shared indexes are 0 based so for e.g. 8 shards valid indexes would be 0-7.
