Access historical messages when needed — retention policies ensure you never lose critical events.

Allium is your system of record

Beam is the real-time datastreaming offering within Allium’s broader data platform. Unlike point solutions, the same data powering your streaming also powers your analytics, compliance, and product teams.

Datastreams

Subscribe to full chain topics and process events in your infrastructure.

  1. Choose topics — ethereum.transactions, solana.dex_trades, etc.
  2. Connect your Kafka or Pub/Sub — Events flow automatically
  3. Build your processing — Filter, transform, route to your systems

Beam

Build custom-filtered stream transformations — define filters and transforms in a UI, receive only what you need.

Define your filters — Contract addresses, wallet set lookups (100K+ addresses), value thresholds

Add transformations — Reshape data, extract fields, enrich events

Choose your sink — Kafka, SNS, Pub/Sub, direct DB

Deploy in 30 seconds — Visual builder or AI Beam Builder

Best for: Notifications, monitoring, alerting — custom-filtered streams without building infrastructure

Why teams choose Beam:

90%+ reduction in processed events vs full firehose

Zero downstream infrastructure — no Kafka consumers, no transformation pipelines

Engineering months saved — deploy in 30 seconds, not 3-6 months

Why teams choose Allium over webhooks and subgraphs

Webhooks

Best-effort delivery means messages are lost during outages or system downtime.

Teams end up building complex retry logic and backup systems to handle inevitable failures.

Subgraphs

Raw blockchain events require specialized knowledge to decode and query.

GraphQL adds complexity and learning curve.

Indexing costs scale exponentially with query volume, making production usage expensive.

Teams need blockchain expertise to maintain and troubleshoot.

Guaranteed delivery with enterprise message brokers (Kafka, Pub/Sub, SNS)

Decoded & enriched data with consistent schemas

Standard SQL without graph expertise

Predictable scaling costs for production workloads

Broader data platform — streaming, analytics, compliance from one source

FAQ

Should I use Datastreams or Beam?

Use Datastreams if you have streaming infrastructure and want full chain data with maximum control. Use Beam if you want custom-filtered stream transformations without building or maintaining real-time infrastructure — ideal for notifications, monitoring, and alerting.

Can I use both?

Yes. Some teams use Datastreams for analytics (full data to data lake) and Beam for user-facing features (custom-filtered streams for notifications).

What’s the latency difference?

Datastreams delivers at P50 ~5 seconds. Beam delivers at P50 <2 seconds. Beam is faster because filtering and transformation happen at source through co-located processing.

How much infrastructure does Beam eliminate?

Beam eliminates downstream Kafka consumers, transformation pipelines, and filtering logic.

How much engineering time does Beam save?

Building custom streaming pipelines typically takes 3-6 months. Beam deploys in 30 seconds with a visual builder or AI Beam Builder.

Does Beam support my sink?

Beam supports Kafka, AWS SNS, Google Pub/Sub, and direct database sinks (ClickHouse, Postgres).

What kind of filters and transformations does Beam support?

Filters: contract address filtering, large wallet set lookups (100K+ addresses), value thresholds, event type selection. Transformations: data reshaping, field extraction, event enrichment — all defined in the UI.

Why Allium over Goldsky?

Goldsky Mirror is streaming-only. Allium gives you streaming plus Explorer, Datashares, APIs, and attribution data — all from the same standardized schemas. When multiple teams reference the same Allium data, switching creates coordination cost across finance, product, engineering, and compliance.
