Why teams connect Apache Cassandra and Redis Enterprise

Keep Apache Cassandra and Redis Enterprise synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between Apache Cassandra and Redis Enterprise continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • Consolidate data from multiple keyspaces or clusters into one reporting store.
  • Replicate high-volume event or profile tables from Cassandra into a warehouse for analytics that CQL cannot express.
  • Write counters and leaderboard state from sorted sets back to an operational database for durable reporting.
  • Cache CRM or ERP records into Redis hashes so applications read customer data with sub-millisecond in-memory latency instead of hitting SaaS APIs.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

Cross-engine sync

Keep the same dataset live in both Apache Cassandra and Redis Enterprise, so each workload runs on the engine that suits it.

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

What you can sync between Apache Cassandra and Redis Enterprise

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 Redis Enterprise objects
Counters Increment-only counter columns, usually read-only in syncs. Keys (Strings) Simple key-value pairs used to cache individual synced records or lookup values.
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Hashes Field-value maps that commonly hold one synced row per hash, keyed by record ID.
Tables Wide-column tables addressed by partition key, the unit of row-level sync. JSON documents Native JSON storage (RedisJSON) for nested records synced from APIs or document stores.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Sets Unordered unique-member collections used for membership checks like segment or ID lists.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Sorted Sets Score-ordered collections used for rankings, priority queues, and time-ordered indexes.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Lists Ordered sequences often used as lightweight queues fed by sync events.

How the Apache Cassandra and Redis Enterprise 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

Redis Enterprise

Integration surface
Redis wire protocol (RESP) via client libraries; separate REST API for cluster management
Authentication
Password or ACL-based credentials, typically over TLS
Change detection
Keyspace notifications over pub/sub or reads from Redis Streams; no transaction-log CDC surface for data
Capabilities
read · write
Rate limits
Throughput is bounded by provisioned cluster capacity rather than published API rate limits
How it works

How to connect Apache Cassandra to Redis Enterprise — 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.
