host [string]

redis host

port [int]

redis port

keys [string]

keys pattern

Tips:Redis source connector support fuzzy key matching, user needs to ensure that the matched keys are the same type

data_type [string]

redis data types, support key hash list set zset

  • key

    The value of each key will be sent downstream as a single row of data. For example, the value of key is SeaTunnel test message, the data received downstream is SeaTunnel test message and only one message will be received.

  • hash

    The hash key-value pairs will be formatted as json to be sent downstream as a single row of data. For example, the value of hash is name:tyrantlucifer age:26, the data received downstream is {"name":"tyrantlucifer", "age":"26"} and only one message will be received.

  • list

    Each element in the list will be sent downstream as a single row of data. For example, the value of list is [tyrantlucier, CalvinKirs], the data received downstream are tyrantlucifer and CalvinKirs and only two message will be received.

  • set

    Each element in the set will be sent downstream as a single row of data For example, the value of set is [tyrantlucier, CalvinKirs], the data received downstream are tyrantlucifer and CalvinKirs and only two message will be received.

  • zset

    Each element in the sorted set will be sent downstream as a single row of data For example, the value of sorted set is [tyrantlucier, CalvinKirs], the data received downstream are tyrantlucifer and CalvinKirs and only two message will be received.

auth [String]

redis authentication password, you need it when you connect to an encrypted cluster

format [String]

the format of upstream data, now only support json text, default json.

when you assign format is json, you should also assign schema option, for example:

upstream data is the following:


{"code": 200, "data": "get success", "success": true}

you should assign schema as the following:


schema {
fields {
code = int
data = string
success = boolean
}
}

connector will generate data as the following:

codedatasuccess
200get successtrue

when you assign format is text, connector will do nothing for upstream data, for example:

upstream data is the following:


{"code": 200, "data": "get success", "success": true}

connector will generate data as the following:

content
{"code": 200, "data": "get success", "success": true}

schema [Config]

fields [Config]

the schema fields of upstream data

common options

Source plugin common parameters, please refer to Source Common Options for details

Example

simple:

  Redis {
host = localhost
port = 6379
keys = "key_test*"
data_type = key
format = text
}
  Redis {
host = localhost
port = 6379
keys = "key_test*"
data_type = key
format = json
schema {
fields {
name = string
age = int
}
}
}
