Why teams connect Apache Cassandra and Google Cloud Platform

Connect Apache Cassandra and Google Cloud Platform with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want Apache Cassandra's rows in Google Cloud Platform, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in Apache Cassandra where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in Apache Cassandra sync into Google Cloud Platform in real time, and result tables in Google Cloud Platform sync back into Apache Cassandra, with schema and type mapping between the two systems handled for you.

Common use cases

  • Publish change events to Pub/Sub so downstream services react to record updates as they happen.
  • Sync customer profile data between Cassandra and a CRM so operational apps and sales tools agree.
  • Write attributes computed elsewhere (scores, preferences) back into Cassandra tables serving low-latency reads.

Operational data in the warehouse, minus the pipeline

Rows from Apache Cassandra land in Google Cloud Platform as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Google Cloud Platform sync into Apache Cassandra, where whatever reads from that database gets them without querying the warehouse.

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

What you can sync between Apache Cassandra and Google Cloud Platform

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Apache Cassandra objects Google Cloud Platform objects
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Spanner tables Strongly consistent relational tables accessed via SQL for transactional workloads.
Tables Wide-column tables addressed by partition key, the unit of row-level sync. BigQuery datasets Namespaces that group tables; syncs target tables within a dataset.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. BigQuery tables The primary analytics destination, written through load jobs or the Storage Write API and queried with SQL.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Cloud SQL databases Managed Postgres, MySQL, and SQL Server instances synced like ordinary relational databases.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Cloud Storage objects Staging area for file-based bulk loads into BigQuery and other services.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Pub/Sub topics Event streams used to move change events between systems in near real time.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever Apache Cassandra or Google Cloud Platform data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single Apache Cassandra or Google Cloud Platform record.

Observability

Monitoring

Track your Apache Cassandra ⇄ Google Cloud Platform sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Apache Cassandra and Google Cloud Platform.

How the Apache Cassandra and Google Cloud Platform connectors work

Apache Cassandra

Integration surface
CQL over the Cassandra native binary protocol
Authentication
Database credentials (password authenticator); TLS and role-based grants where configured
Change detection
Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns
Capabilities
read · write · CDC
Rate limits
No API quotas; throughput is governed by cluster capacity and consistency-level choices

Google Cloud Platform

Integration surface
Per-service REST and gRPC APIs; BigQuery speaks SQL and Cloud SQL exposes standard database wire protocols
Authentication
IAM service accounts with OAuth 2.0 tokens
Change detection
Varies by service: log-based CDC on Cloud SQL (logical replication or binlog, also via Datastream), Pub/Sub for event delivery, polling for BigQuery tables
Capabilities
read · write · CDC · webhooks
Rate limits
Quotas are set per service and per project; BigQuery, Pub/Sub, and Cloud SQL each enforce their own limits
How it works

How to connect Apache Cassandra to Google Cloud Platform — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate Apache Cassandra and Google Cloud Platform with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
