Why teams connect Apache Impala and SingleStore

Connect SingleStore and Apache Impala 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 SingleStore's rows in Apache Impala, 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 SingleStore where the services that read from it get them at normal query latency.

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

Common use cases

  • Read new partitions incrementally from Parquet tables and land them in a cloud warehouse during migration.
  • Publish Impala query results (aggregates, KPIs) to CRMs or spreadsheets on a schedule.
  • Consolidate data from transactional databases and SaaS apps into one store that handles both lookups and scans.
  • Keep reference data consistent between SingleStore and application databases.

Fresh analytics without loading windows

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

Offload heavy reads

Point analytical queries at the synced copy in Apache Impala and keep SingleStore focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from SingleStore land in Apache Impala as they change, replacing hand-built CDC and batch extract jobs.

What you can sync between Apache Impala and SingleStore

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 Impala objects SingleStore objects
Tables HDFS or object-storage backed tables (commonly Parquet) read at interactive speed. Databases The connection target containing the tables a sync addresses.
Partitions Partition values used to limit scans and drive incremental reads. Tables (rowstore and columnstore) Primary read/write target; storage type affects whether a table suits point lookups or scans.
Views Logical views readable as modeled sources. Views Read-only projections used as curated sync sources.
Kudu Tables Kudu-backed tables that support row-level insert, update, upsert, and delete. Reference Tables Small tables replicated to every node, often used for dimension data in syncs.
External Tables Tables over files loaded by other tools, queryable without data movement. Pipelines Native ingestion jobs from Kafka or object storage that coexist with external syncs.
Users and Roles Principals (often via Ranger/Sentry) used to grant scoped read access. Stored Procedures Existing logic sometimes invoked on write paths.

How the Apache Impala and SingleStore connectors work

Apache Impala

Integration surface
SQL over JDBC/ODBC (HiveServer2-compatible protocol)
Authentication
Deployment-dependent: Kerberos, LDAP, or username/password
Change detection
Polling on partition or timestamp columns; no change log exposed for external consumers
Capabilities
read · write
Rate limits
No API quotas; concurrency is bounded by cluster resources and admission control settings

SingleStore

Integration surface
SQL over the MySQL wire protocol; an HTTP Data API is also available for SQL over REST
Authentication
Database credentials
Change detection
Polling on timestamp or watermark columns; the platform also provides change-observation features in recent versions
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by workspace or cluster size
How it works

How to connect Apache Impala to SingleStore — three steps, no code
