document. The metadata in the specified field should be data that
52

is used to label a unique series of documents.

* - ``granularity``
55
- - The ``granularity`` field allows specifying a coarser granularity so
56
- measurements over a longer time span can be more efficiently stored
57
- and queried.
57

63
+ If you set the ``granularity`` parameter, you can't set the
64

* - ``expireAfterSeconds``
62
- - The ``expireAfterSeconds`` field enables automatic deletion of
63
- documents older than the specified number of seconds.
67
+ - number
68
+ - Enables the automatic deletion of documents that are older than
69
+ the specified number of seconds.
70

71
+ * - ``bucketMaxSpanSeconds``
72
+ - number
73
+ - Specifies the maximum time span between measurements in a bucket.
74
+
75
+ The value of ``bucketMaxSpanSeconds`` must be the same as
76
+ ``bucketRoundingSeconds``. If you set the ``bucketMaxSpanSeconds``,
77
+ parameter, you can't set the ``granularity`` parameter.
78

79
+ * - ``bucketRoundingSeconds``
80
+ - number
81
+ - Specifies the time interval that determines the starting timestamp
82
+ for a new bucket.
83
+
84
+ The value of ``bucketRoundingSeconds`` must be the same as
85
+ ``bucketMaxSpanSeconds``. If you set the ``bucketRoundingSeconds``,
86
