📥 **Count**
 The total number of lines to output.

- **optional**:
   Indicates whether the parameter is optional.
- **uint**:
   Specifies the data type for this parameter.
- **default**:
   9.223372036854776e+18 (Infinitely by default).

📥 **Decoding (decoding)**
 Configure how events are decoded from raw bytes.

- **decoding.avro**:
   Apache Avro-specific encoder options (required when codec is "avro").
  - **schema**:
     Avro schema definition (required).
  - **strip\_schema\_id\_prefix**:
     Remove the schema ID prefix from Confluent Kafka messages (true/false).
- **decoding.codec (default: bytes)**:
   The codec to use for decoding events. Options include:
  - avro: Decodes as Apache Avro.
  - bytes: Uses the raw bytes as-is.
  - gelf: Decodes as a GELF message.
  - influxdb: Decodes as InfluxDB Line Protocol.
  - json: Decodes as JSON.
  - native: Decodes as native Protocol Buffers.
  - native\_json: Decodes as native JSON format.
  - protobuf: Decodes as Protobuf.
  - syslog: Decodes as Syslog.
  - vrl: Decodes the raw bytes as input to a VRL program.
- **decoding.gelf**:
   GELF-specific decoding options (relevant when codec is "gelf").
  - **lossy**:
     Determines whether to replace invalid UTF-8 sequences (true/false). Default: true.
- **decoding.influxdb**:
   InfluxDB-specific decoding options (relevant when codec is "influxdb").
  - **lossy**:
     Determines whether to replace invalid UTF-8 sequences (true/false). Default: true.
- **decoding.json**:
   JSON-specific decoding options (relevant when codec is "json").
  - **lossy**:
     Determines whether to replace invalid UTF-8 sequences (true/false). Default: true.
- **decoding.native\_json**:
   Worker's native JSON-specific decoding options (relevant when codec is "native\_json").
  - **lossy**:
     Determines whether to replace invalid UTF-8 sequences (true/false). Default: true.
- **decoding.protobuf**:
   Protobuf-specific decoding options (relevant when codec is "protobuf").
  - **desc\_file**:
     Path to the protobuf descriptor set file.
  - **message\_type**:
     Fully qualified message type for serializing.
- **decoding.syslog**:
   Syslog-specific decoding options (relevant when codec is "syslog").
  - **lossy**:
     Determines whether to replace invalid UTF-8 sequences (true/false). Default: true.
- **decoding.vrl**:
   VRL-specific decoding options (required when codec is "vrl").
  - **source**:
     VRL program to decode the message (required).
  - **timezone**:
     Timezone for timestamp conversion (optional).

📥 **Framing (framing)**
 Configure how byte streams are split into messages.

- **method (default: bytes)**:
   Select the framing strategy. Options include:
  - bytes
  - character\_delimited
  - chunked\_gelf
  - length\_delimited
  - newline\_delimited
  - octet\_counting
- **Framing-specific settings**:
  - **character\_delimited**:
    - **delimiter**: ASCII character to separate frames (required).
    - **max\_length**: Max size of a frame.
  - **chunked\_gelf**:
    - **decompression**: Options for decompression (Auto, Gzip, Zlib, None).
    - **max\_length**, **pending\_messages\_limit**, **timeout\_secs**.
  - **length\_delimited**:
    - **length\_field\_is\_big\_endian**: Whether the length field is big-endian (default: true).
    - **length\_field\_length**, **length\_field\_offset**, **max\_frame\_length**.
  - **newline\_delimited** and **octet\_counting**:
    - **max\_length**: Max size of a frame.

📥 **Interval**
 Time to pause between each batch of output lines.

- **default**:
   1 second (default). Set to 0.0 for no delay.

📥 **Lines**
 List of lines to output (relevant when format = "shuffle").

- **required**:
   Specifies the required input.

📥 **Sequence**
 If true, each output line starts with an increasing sequence number, beginning with 0.

- **default**:
   False (default). Relevant when format = "shuffle".
