Why teams connect Azure Synapse Analytics and Elasticsearch

Connect Elasticsearch and Azure Synapse Analytics 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 Elasticsearch's rows in Azure Synapse Analytics, 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 Elasticsearch where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in Elasticsearch sync into Azure Synapse Analytics in real time, and result tables in Azure Synapse Analytics sync back into Elasticsearch, with schema and type mapping between the two systems handled for you.

Common use cases

  • Load CRM and ERP records into Synapse dedicated SQL pool tables for enterprise reporting.
  • Publish warehouse aggregates (account health scores, LTV) from Synapse back into operational tools like a CRM.
  • Mirror support tickets into an index used for full-text search and agent-assist tooling.
  • Feed enriched customer records into an index used for vector or hybrid search in AI applications.

Offload heavy reads

Point analytical queries at the synced copy in Azure Synapse Analytics and keep Elasticsearch focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Elasticsearch land in Azure Synapse Analytics as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Azure Synapse Analytics sync into Elasticsearch, where whatever reads from that database gets them without querying the warehouse.

What you can sync between Azure Synapse Analytics and Elasticsearch

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.

Azure Synapse Analytics objects Elasticsearch objects
Schemas Namespaces that separate staging, integration, and presentation layers. Ingest pipelines Server-side transforms applied to documents as a sync writes them.
Materialized views Precomputed aggregates that speed reads of frequently synced result sets. Index templates Reusable settings and mappings applied automatically to new indices a sync creates.
SQL pools Dedicated or serverless compute contexts that determine how and where queries run. Indices Target containers for synced records; each holds a table-like collection of JSON documents.
Tables (dedicated SQL pool) Distributed warehouse tables that serve as sync destinations for analytics workloads. Documents The unit of sync; JSON records created, updated, and deleted by _id.
External tables Tables over files in the data lake, queried through serverless SQL and often read-only in syncs. Index mappings Field type definitions that determine how synced fields are indexed and queried.
Views Curated projections used when downstream tools should not read base tables directly. Aliases Stable read/write names that let a sync cut over between index versions without downtime.

How the Azure Synapse Analytics and Elasticsearch connectors work

Azure Synapse Analytics

Integration surface
SQL wire protocol (TDS) with T-SQL for SQL pools; additional Spark and pipeline surfaces exist but syncs use the SQL endpoint
Authentication
SQL authentication or Microsoft Entra ID
Change detection
Polling on watermark columns; Synapse SQL pools do not expose log-based CDC for downstream consumers
Capabilities
read · write

Elasticsearch

Integration surface
REST API (JSON over HTTP)
Authentication
API keys or basic authentication; Elastic Cloud also issues service account tokens
Change detection
Polling on timestamp or sequence fields; Elasticsearch does not expose a native change feed or webhooks
Capabilities
read · write
Rate limits
No fixed request quota; throughput is bounded by cluster sizing, thread pools, and bulk queue capacity
