Why teams connect Apache Impala and Exasol

Keep tables consistent across Apache Impala and Exasol, 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 Exasol 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

  • Serve fast extracts of Hadoop-resident tables to operational databases and SaaS tools through Impala instead of slow batch engines.
  • Sync mutable reference data into Kudu tables via Impala so row-level updates are possible on the Hadoop side.
  • Load CRM and ERP records into Exasol tables on a schedule so analysts query fresh operational data.
  • Sync computed metrics or customer segments from Exasol back into a CRM for sales and marketing use (reverse ETL).

Shared datasets across teams

Where different teams run different warehouses, sync the curated tables both rely on so their metrics agree by construction.

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.

What you can sync between Apache Impala and Exasol

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 Exasol objects
Databases Namespaces shared with the Hive Metastore that scope tables. Views Read-only query surfaces often used as curated sources for reverse ETL.
Tables HDFS or object-storage backed tables (commonly Parquet) read at interactive speed. Virtual schemas Federated views over external sources; useful for deciding what needs physical replication.
Partitions Partition values used to limit scans and drive incremental reads. UDF scripts In-database functions that can transform synced data after load.
Views Logical views readable as modeled sources. Users and roles Grant read/write access for the dedicated integration account.
Kudu Tables Kudu-backed tables that support row-level insert, update, upsert, and delete. Schemas Namespaces that group the tables a sync reads from or writes into.
External Tables Tables over files loaded by other tools, queryable without data movement. Tables Primary sync target; columnar relational tables written with standard SQL.

How the Apache Impala and Exasol 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

Exasol

Integration surface
SQL over JDBC/ODBC drivers and a WebSocket-based client protocol
Authentication
Database credentials (username and password)
Change detection
Polling with timestamp or key columns; Exasol does not expose a transaction-log change feed to clients
Capabilities
read · write
Rate limits
No API quota; concurrency is bounded by cluster resources and session limits
