Configurações
Nome | Descrição | |

timeseries.timefield | Type: string Description: The name of the top-level field in the source data that contains time
information that you want to associate with the new document in the
time series collection. Default: ""Accepted Values: An empty string or the name of a field
that contains a BSON DateTime value | |
timeseries.timefield.auto.convert.date.format | Type: string Description: The date format pattern the connector should use to convert the
source data contained in the field specified by the
timeseries.timefield setting.
The connector passes the date format pattern to the Java
DateTimeFormatter.ofPattern(pattern, locale)
method to perform date and time conversions on the time field.If the date value from the source data only contains date information,
the connector sets the time information to the start of the specified

connector sets the offset to UTC. Default: Accepted Values: A valid DateTimeFormatter format | |
timeseries.timefield.auto.convert | Type: boolean Description: Whether to convert the data in the field into the BSON Date
format.When set to true, the connector uses the milliseconds
after epoch and discards fractional parts if the value is
a number. If the value is a string, the connector uses the

timeseries.granularity | Type: string Description: The expected interval between subsequent measurements of your
source data. For more information on this setting, see the
MongoDB server manual page on Granularity for Time
Series Data. Optional Default: ""Accepted Values: "", "seconds", "minutes", "hours" |
