Why teams connect Apache Kylin and Google AlloyDB
Flow Apache Kylin data into Google AlloyDB in real time — no exports, no schedulers, no custom scripts.
Apache Kylin is a read-only source: Stacksync reads its data in real time and delivers it into Google AlloyDB, so Google AlloyDB always reflects the current state of Apache Kylin — without exports, scripts, or schedulers.
Operational databases and analytical warehouses want the same data at different moments. Analysts want Google AlloyDB's rows in Apache Kylin, 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 Google AlloyDB where the services that read from it get them at normal query latency.
Common use cases
- 01 Read pre-aggregated metrics from Kylin and sync them into CRM fields or planning spreadsheets on a schedule.
- 02 Expose Kylin query results to operational dashboards without granting access to the underlying Hadoop data.
- 03 Consolidate SaaS data into AlloyDB and serve analytics from its columnar engine without a separate OLAP store.
- 04 Migrate workloads from self-managed Postgres while keeping existing syncs pointed at a compatible endpoint.
Common sync patterns
Offload heavy reads
Point analytical queries at the synced copy in Apache Kylin and keep Google AlloyDB focused on its operational workload.
Operational data in the warehouse, minus the pipeline
Rows from Google AlloyDB land in Apache Kylin as they change, replacing hand-built CDC and batch extract jobs.
Serve warehouse results at database speed
Aggregates or model outputs computed in Apache Kylin sync into Google AlloyDB, where whatever reads from that database gets them without querying the warehouse.
What you can sync between Apache Kylin and Google AlloyDB
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 Kylin objects | Google AlloyDB objects | How this pairing syncs | |
|---|---|---|---|
| Source Tables Hive or other upstream tables that builds read from. | Materialized Views Precomputed aggregates refreshed and synced outward on a schedule. | Source Tables is specific to Apache Kylin and Materialized Views to Google AlloyDB — each maps to any object or custom field on the other side. | |
| Segments Time-ranged build units that partition pre-computed data. | Indexes Keep sync key lookups fast on high-volume tables. | Segments is specific to Apache Kylin and Indexes to Google AlloyDB — each maps to any object or custom field on the other side. | |
| Build Jobs Batch jobs that compute or refresh segments, monitored via the REST API. | Sequences ID generation relevant when external systems insert rows. | Build Jobs is specific to Apache Kylin and Sequences to Google AlloyDB — each maps to any object or custom field on the other side. | |
| Projects Top-level workspaces that group models, tables, and jobs. | Replication Slots Logical replication artifacts that back log-based change capture. | Projects is specific to Apache Kylin and Replication Slots to Google AlloyDB — each maps to any object or custom field on the other side. | |
| Models Star-schema definitions over source tables that determine what can be queried. | Databases Standard PostgreSQL databases within an AlloyDB cluster that syncs connect to. | Models is specific to Apache Kylin and Databases to Google AlloyDB — each maps to any object or custom field on the other side. | |
| Cubes / Indexes Pre-computed aggregate structures that answer queries at low latency. | Schemas Namespaces used to separate synced SaaS data from application tables. | Cubes / Indexes is specific to Apache Kylin and Schemas to Google AlloyDB — each maps to any object or custom field on the other side. |
How changes propagate between Apache Kylin and Google AlloyDB
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Apache Kylin Google AlloyDB Interval-based propagation
DetectionStacksync polls Apache Kylin for changes on an incremental schedule, reading only records changed since the previous pass. Data freshness follows segment build and refresh jobs, so integrations poll query results.
DeliveryEach detected change is applied to Google AlloyDB as a row-level write, with types converted between the two schemas.
Google AlloyDB Apache Kylin Sub-second propagation
DetectionChanges in Google AlloyDB are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication.
DeliveryApache Kylin does not accept inbound record writes, so this direction carries requests rather than records: Apache Kylin's output flows back as field updates on the originating Google AlloyDB records.
Rate-limit considerations
- Apache Kylin: No fixed API quotas; query capacity depends on the deployment and pre-computed index coverage.
- Google AlloyDB: No API-style rate limits; throughput is bounded by instance size.

FAQ
Apache Kylin and Google AlloyDB integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between Apache Kylin and Google AlloyDB — Apache Kylin is a read-only source, so data flows from it into the other system: authenticate both systems, choose the objects to sync, map fields visually, and changes propagate in milliseconds — no code required.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Apache Kylin and Google AlloyDB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Apache Kylin–Google AlloyDB integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Apache Kylin and Google AlloyDB. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Apache Kylin: Not applicable for row-level capture; data freshness follows segment build and refresh jobs, so integrations poll query results. On Google AlloyDB: Log-based CDC via PostgreSQL logical replication; polling on timestamp columns as a fallback. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Apache Kylin side: Models, Cubes / Indexes, Source Tables, Segments, plus custom fields where Apache Kylin exposes them. On the Google AlloyDB side: Replication Slots, Databases, Schemas, Tables. Stacksync auto-detects both schemas and converts types between the two systems.
-
Apache Kylin is a read-only source, so this integration runs one-way: Stacksync reads from Apache Kylin in real time and delivers into Google AlloyDB. Field mapping and monitoring work the same as for two-way pairs.
