Parameters for creating a new stream.

Fields

name: String

Human-readable label identifying the stream.

region: StreamRegion

Geographic region where the stream runs.

network: String

Blockchain network to stream from (e.g. ethereum-mainnet).

dataset: StreamDataset

Type of on-chain data to stream.

start_range: i64

Block number to begin streaming from.

end_range: i64

Block number to stop streaming at; -1 for continuous operation.

destination_attributes: DestinationAttributes

Destination-specific configuration (webhook URL, S3 bucket, DB credentials, etc.).

plan: String

Billing plan associated with the stream.

threshold_fetch_buffer: i64

Buffer size used by the stream fetcher before delivery.

dataset_batch_size: Option<i64>

Number of blocks grouped together per delivered batch.

max_batch_size: Option<i64>

Upper bound on batch size when elastic batching is enabled.

max_buffer_range_size: Option<i64>

Maximum number of buffered blocks waiting to be processed.

max_buffer_processing_workers: Option<i64>

Maximum number of worker threads processing buffered batches.

keep_distance_from_tip: Option<i64>

Number of blocks to stay behind the chain tip to reduce exposure to reorgs.

filter_function: Option<String>

Base64-encoded filter function applied to each batch before delivery.

filter_language: Option<FilterLanguage>

Language the filter function is written in.

address_book_config: Option<AddressBookConfig>

Optional address book to evaluate the filter against.

include_stream_metadata: Option<StreamMetadataLocation>

Where to include stream metadata in delivered payloads.

product_type: Option<ProductType>

Billing product type the stream is associated with.

status: Option<StreamStatus>

Initial stream state (active or paused). Defaults to active when omitted.

notification_email: Option<String>

Email address that receives stream termination or failure alerts.

charge_min_cap: Option<i32>

Minimum charge cap applied to the stream’s billing.

fix_block_reorgs: Option<i32>

Flag (0 or 1) enabling automatic re-streaming of blocks affected by chain reorganizations.

elastic_batch_enabled: Option<bool>

When enabled, batch size is reduced toward 1 as the stream catches up to the chain tip.

extra_destinations: Option<Vec<DestinationAttributes>>

Additional destinations that receive the same batches alongside the primary.
