About Metadata

For better understanding of the parameters from the Advanced category let’s consider the time series shown in the picture below:

Note that for all time series specified data source and store are the same, but types of addresses and comments are different.

Case when default store parameters are used. After data source value changes request SELECT * FROM "timeseries"."autogen"."tssamples" GROUP BY "tsid" ORDER BY DESC LIMIT 1 will return the following result:

time	tsid	s	v
2019-09-25 23:12:41	MySeries.Series1	0	25.00
2019-09-25 23:12:41	MyCustomID	0	25.00
2019-09-25 23:12:41	22ePXYjPQ0GM/3iyM+Dii12+3n4=	0	25.00

Case when Add Time Series Comment to Tag parameter is True. After data source value changes the same request will return the following result:

time	tsid	tsc	s	v
2019-09-25 23:57:16	MySeries.Series1	S1 Comment	0	99.00
2019-09-25 23:57:16	MyCustomID	S3 Comment	0	99.00
2019-09-25 23:57:16	22ePXYjPQ0GM/3iyM+Dii12+3n4=	S2 Comment	0	99.00

Thus tsc tag will be added to the record metadata for each time series and it will contain time series comment.

Case when Add Time Series Path to Tag parameter is True. After data source value changes the same request will return the following result:

time	tsid	tsp	s	v
2019-09-26 00:09:58	MySeries.Series1	MySeries.Series1	0	117.00
2019-09-26 00:09:58	MyCustomID	MySeries.Series3	0	117.00
2019-09-26 00:09:58	22ePXYjPQ0GM/3iyM+Dii12+3n4=	MySeries.Series2	0	117.00

Thus tsp tag will be added to the record metadata for each time series and it will contain path to the series.

Case when Add Server UID to Tag parameter is True. After data source value changes the same request will return the following result:

time	tsid	su	s	v
2019-09-26 00:09:58	MySeries.Series1	CeSqAF5sGUqMJqdilungXg==	0	33.00
2019-09-26 00:09:58	MyCustomID	CeSqAF5sGUqMJqdilungXg==	0	33.00
2019-09-26 00:09:58	22ePXYjPQ0GM/3iyM+Dii12+3n4=	CeSqAF5sGUqMJqdilungXg==	0	33.00

Thus su tag will be added to the record metadata for each time series and it will contain unique server identifier in the format of Base64.

You can use different combinations of flags from the Advanced category in order to define several meta-tags.
