	// The filter to apply to the query. Only one filter can be used at a time. When
	// the filter is used, jobStatus is ignored. The filter doesn't apply to child
	// jobs in an array or multi-node parallel (MNP) jobs. The results are sorted by
	// the createdAt field, with the most recent jobs being first. JOB_NAME The value
	// of the filter is a case-insensitive match for the job name. If the value ends
	// with an asterisk (*), the filter matches any job name that begins with the
	// string before the '*'. This corresponds to the jobName value. For example, test1
	// matches both Test1 and test1 , and test1* matches both test1 and Test10 . When
	// the JOB_NAME filter is used, the results are grouped by the job name and
	// version. JOB_DEFINITION The value for the filter is the name or Amazon Resource
	// Name (ARN) of the job definition. This corresponds to the jobDefinition value.
	// The value is case sensitive. When the value for the filter is the job definition
	// name, the results include all the jobs that used any revision of that job
	// definition name. If the value ends with an asterisk (*), the filter matches any
	// job definition name that begins with the string before the '*'. For example, jd1
	// matches only jd1 , and jd1* matches both jd1 and jd1A . The version of the job
	// definition that's used doesn't affect the sort order. When the JOB_DEFINITION
	// filter is used and the ARN is used (which is in the form
	// arn:${Partition}:batch:${Region}:${Account}:job-definition/${JobDefinitionName}:${Revision}
	// ), the results include jobs that used the specified revision of the job
	// definition. Asterisk (*) isn't supported when the ARN is used. BEFORE_CREATED_AT
	// The value for the filter is the time that's before the job was created. This
	// corresponds to the createdAt value. The value is a string representation of the
	// number of milliseconds since 00:00:00 UTC (midnight) on January 1, 1970.
	// AFTER_CREATED_AT The value for the filter is the time that's after the job was
	// created. This corresponds to the createdAt value. The value is a string
	// representation of the number of milliseconds since 00:00:00 UTC (midnight) on
	// January 1, 1970.
