CTSDB InfluxDB Offline Single Table Read Node Configuration
Parameters
Description
Data Source
Select available CTSDB InfluxDB data source in current project.
Database
Supports selecting or manually entering the database name to be read
By default, the database bound to the data source is used as the default database. Other databases need to be manually entered.
If the data source network is not connected and the database information cannot be fetched directly, you can manually enter the database name. Data synchronization can still be performed when the Data Integration network is connected.
Measurement
Supports selection or manual input of the logical grouping of time series data to be read.
Time Checkpoint Precision
Precision of the start and end time points:
If hours are selected, reading starts/ends from yyyyMMddHH.
If minutes are selected, reading starts/ends from yyyyMMddHHmm.
If seconds are selected, reading starts/ends from yyyyMMddHHmmss.
Start Time Checkpoint
Start time for reading CTSDB InfluxDB (the time in the CTSDB InfluxDB database is in UTC time). You can enter a specific time value or a time parameter. If the time point precision is specified to the second, the time value could be: 20200101123027, and the time parameter: ${yyyyMMddHHmmss}. Time parameters support operators like "+" and "-", e.g., ${yyyyMMddHHmmss-3H}
End Time Checkpoint
End time for reading CTSDB InfluxDB (the time in the CTSDB InfluxDB database is in UTC time). You can enter a specific time value or a time parameter. If the time point precision is specified to the second, the time value could be: 20200101123027, and the time parameter: ${yyyyMMddHHmmss}. Time parameters support operators like "+" and "-", e.g., ${yyyyMMddHHmmss-3H}
Batch Size
Number of entries read from CTSDB InfluxDB each time. Default is 1000 if not filled
Filter Conditions (Optional)
Fill in the corresponding filter statement based on the data type. This statement will serve as the filter condition for the data to be synchronized.
CTSDB InfluxDB Offline Single Table Write Node Configuration
Parameters
Description
Data Destination
Select available CTSDB InfluxDB data source in current project.
Database
Supports selection or manual input of the database name to write to
By default, the database bound to the data source is used as the default database. Other databases need to be manually entered.
If the data source network is not connected and the database information cannot be fetched directly, you can manually enter the database name. Data synchronization can still be performed when the Data Integration network is connected.
Measurement
Supports selection or manual input of the logical grouping of time series data to be written.
Timestamp Precision
The precision of time data, available precisions include ns (Nanoseconds), u (microseconds), ms (Milliseconds), s (Seconds), m (minutes), h (Hour).
Whether to Clear Table
You can manually choose whether to clear the CTSDB InfluxDB Data Table before writing to it.
Batch Submission Size
The batch size for one-time Batch Submission of records. This value can significantly reduce the Network Interaction between the data synchronization system and Vertica, while enhancing overall Throughput. However, if the value is set too high, it may result in OOM (Out Of Memory) exceptions during the data synchronization process.
Pre-Executed SQL
SQL statements executed before the synchronization task. Fill in the SQL according to the correct SQL syntax corresponding to the data source type.
Pre-Executed SQL
SQL statements executed after the synchronization task. Fill in the SQL according to the correct SQL syntax corresponding to the data source type.
