Fields

​
entry_point (required)

Path to your WASM plugin entrypoint (e.g., wrapper.go, main.py, . for module root). This is used by compile-wasm command.
tangent.yaml
entry_point: main.py

​
module_type (required)

The language used by your WASM plugin. This is used by compile-wasm command. Options: go, py
tangent.yaml
module_type: go

​
batch_size (optional)

Tangent buffers logs in memory before flushing to your WASM plugin. Logs are flushed when either batch_size or batch_age is reached. batch_size configures the maximum size of logs to buffer before flushing, in KB (default: 256).
tangent.yaml
batch_size: 1024

​
batch_age (optional)

Tangent buffers logs in memory before flushing to your WASM plugin. Logs are flushed when either batch_size or batch_age is reached. batch_age configures the maximum time logs will be buffered before flushing, in milliseconds (default: 5)
tangent.yaml
batch_age: 5

​
workers (optional)

Number of workers threads to spawn (default: number of CPUs)
tangent.yaml
workers: 16

​
sources (required)

Configure log sources. See Sources Pulling from multiple sources is not yet supported. Example:
tangent.yaml
sources:
  socket_main:
    type: socket
    socket_path: "/tmp/sidecar.sock"

​
sinks (required)

Configure log sinks. See Sources Sinking into multiple sinks is not yet supported. Example:
tangent.yaml
sinks:
  s3_bucket:
    type: s3
    bucket_name: my-bucket
