Why teams connect Apache Impala and Dremio

Keep tables consistent across Apache Impala and Dremio, for a migration, a multi-warehouse stack, or a dataset two platforms both need.

Companies end up with two warehouses for practical reasons: a migration in progress, teams that standardized on different platforms, an acquisition, or tools that only connect to one of them. The result is the same dataset maintained twice, with duplicated pipelines and numbers that almost match.

Stacksync syncs tables between Apache Impala and Dremio continuously, in either or both directions. Rows changed on one platform appear on the other within seconds, with schema and type mapping handled, so both warehouses answer questions with the same data.

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.
  • Reverse-ETL aggregates computed over lake data out to CRMs and finance tools for business users.
  • Publish operational database tables into Iceberg via Dremio so the lakehouse reflects current application state.

Consolidation after M&A

Bring the acquired company's warehouse data across continuously instead of through one-off dumps.

Migration without a big bang

When one platform is replacing the other, keep tables mirrored while workloads move over gradually, and cut over with nothing to backfill.

Serve tools that only connect to one platform

Mirror the datasets a BI tool, notebook, or application needs onto the platform it can actually reach.

What you can sync between Apache Impala and Dremio

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 Dremio objects
Partitions Partition values used to limit scans and drive incremental reads. Spaces and folders Namespaces that organize virtual datasets and govern access.
Views Logical views readable as modeled sources. Reflections Materialized accelerations that make repeated extraction queries cheaper.
Kudu Tables Kudu-backed tables that support row-level insert, update, upsert, and delete. Jobs Query execution records useful for monitoring sync workloads.
External Tables Tables over files loaded by other tools, queryable without data movement. Sources Connected storage and database systems (S3, ADLS, relational databases) Dremio queries in place.
Users and Roles Principals (often via Ranger/Sentry) used to grant scoped read access. Physical datasets Tables and files promoted from sources; the raw data a sync ultimately reads.
Databases Namespaces shared with the Hive Metastore that scope tables. Virtual datasets (views) SQL views layering semantics over physical data; the preferred sync target for curated extracts.

How the Apache Impala and Dremio 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

Dremio

Integration surface
Arrow Flight SQL, JDBC/ODBC, and a REST API
Authentication
Personal access tokens or username/password; OAuth-based SSO on Dremio Cloud
Change detection
Polling via SQL; Iceberg table snapshots can anchor incremental reads; no consumer-facing change feed
Capabilities
read · write
Rate limits
Bounded by engine capacity and workload management rather than API rate limits
How it works

How to connect Apache Impala to Dremio — 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.
