次の構成設定を使用して、MongoDB Kafka Sink Connector が MongoDB 時系列コレクションにデータをシンクする方法を指定します。
カテゴリ別に整理された Sink Connector 構成設定のリストについては、 Sink Connector 構成プロパティ に関するガイドを参照してください。
設定
名前 | 説明 | |
|---|---|---|
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
day. If the date value does not contain the timezone offset, the
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
setting in the following configuration to parse the date:If the connector fails to convert the value, it sends the
original value to the time series collection. Default: falseAccepted Values: true or false | |
timeseries.timefield.auto.convert.locale.language.tag | Type: string Description: Which DateTimeFormatter locale language tag to use with the date
format pattern (e.g. "en-US").To learn more about locales, see the Java SE documentation of Locale. Default: ROOTAccepted Values: A valid Locale language tag format | |
timeseries.metafield | Type: string Description: Which top-level field to read from the source data to describe
a group of related time series documents. IMPORTANT: This field must not be the _id field nor the field you specified
in the timeseries.timefield setting.Default: ""Accepted Values: An empty string or the name of a field
that contains any BSON type except BsonArray. | |
timeseries.expire.after.seconds | Type: int Description: The number of seconds MongoDB should wait before automatically
removing the time series collection data. The connector disables
timed expiry when the setting value is less than 1.To learn more, see Set up Automatic Removal for Time Series Collections
in the MongoDB manual. Default: 0Accepted Values: An integer | |
timeseries.granularity | Type: string Description: The expected interval between subsequent measurements of your
source data. To learn more, see Set Granularity for Time Series Data in the MongoDB manual. Optional Default: ""Accepted Values: "", "seconds", "minutes", "hours" |
