GroupFiles

Grouping files is turned on by default when the input contains more than 50,000 files. To turn on grouping with fewer than 50,000 files, set this parameter to "inPartition". To disable grouping when there are more than 50,000 files, set this parameter to "none".

Type: String

Pattern: ([\u0009\u000B\u000C\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF])*

MaxBand

This option controls the duration in milliseconds after which the s3 listing is likely to be consistent.

Type: Integer

Valid Range: Minimum value of 0.

Required: No

MaxFilesInBand

This option specifies the maximum number of files to save from the last maxBand seconds. If this number is exceeded, extra files are skipped and only processed in the next job run.
