Why teams connect Redis Enterprise and SQL Server

Keep Redis Enterprise and SQL Server 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 Redis Enterprise and SQL Server 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

  • Hydrate session stores and feature stores from a warehouse or operational database on a schedule.
  • Write counters and leaderboard state from sorted sets back to an operational database for durable reporting.
  • Expose SaaS records as SQL Server tables that existing SSRS reports and internal apps can query
  • Mirror on-premises ERP data held in SQL Server into cloud CRM and support systems

Cross-engine sync

Keep the same dataset live in both Redis Enterprise and SQL Server, 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.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

What you can sync between Redis Enterprise and SQL Server

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.

Redis Enterprise objects SQL Server objects
Hashes Field-value maps that commonly hold one synced row per hash, keyed by record ID. Primary and Unique Keys Match keys for idempotent upserts and conflict handling.
JSON documents Native JSON storage (RedisJSON) for nested records synced from APIs or document stores. CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers.
Sets Unordered unique-member collections used for membership checks like segment or ID lists. Stored Procedures T-SQL logic that can validate or post-process synced rows.
Sorted Sets Score-ordered collections used for rankings, priority queues, and time-ordered indexes. Databases Instance-level databases that scope a sync's reads and writes.
Lists Ordered sequences often used as lightweight queues fed by sync events. Schemas Namespaces (dbo and custom) used to organize synced tables.
Streams Append-only logs with consumer groups, used to fan sync events out to downstream services. Tables The primary sync target; rows map to records in connected systems.

How the Redis Enterprise and SQL Server connectors work

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

SQL Server

Integration surface
SQL over the TDS wire protocol (Tabular Data Stream), via ODBC/JDBC/ADO.NET drivers
Authentication
Database credentials entered as a connection string or as parameters (host/user/password) in the Create New Sync page
Change detection
SQL Server Native Change Data Capture (CDC); a DBA runs a one-time setup script with sysadmin privileges to enable CDC and create Stacksync wrapper procedures
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput depends on instance resources, licensing tier, and connection limits
