Data Conversion
마지막 업데이트 시간:2024-01-09 14:54:11
CKafka Connector supports data transformation in multiple ways during data processing as described below:
Data transformation
Enter the raw data. Below is an example.
{"@timestamp": "2022-02-26T22:25:33.210Z","beat": {"hostname": "test-server","ip": "6.6.6.6","version": "5.6.9"},"input_type": "log","message": "{\\"userId\\":888,\\"userName\\":\\"testUser\\"}","offset": 3030131}
CKafka Connector processes the data in the following ways:
Option 1: Quickly define a rule by selecting the corresponding Process Value option.
Option 2: Quickly change the data type of a field by selecting the target data format.
Option 3: Implement the join feature through the JSONPath syntax.
For example, you can use the
$.concat($.data.Response.SubnetSet[0].VpcId,"#",$.data.Response.SubnetSet[0].SubnetId,"#",$.data.Response.SubnetSet[0].CidrBlock)) syntax to concatenate the attributes of VPC and subnet and separate them by #.
