Why teams connect Apache Impala and eClinicalWorks

Get the data locked inside eClinicalWorks into Apache Impala as live tables, and send results back where eClinicalWorks can use them, without writing a pipeline.

Whatever eClinicalWorks is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Diagnostic reports, Patients, Appointments, Encounters from eClinicalWorks into tables in Apache Impala continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Apache Impala can also be written back into fields in eClinicalWorks where the tool can use them.

Common use cases

  • Push referral or intake data captured in external forms into the EHR via HL7 interfaces.
  • Sync patient demographics and appointments into a CRM so patient outreach and intake teams work from current data.
  • Publish Impala query results (aggregates, KPIs) to CRMs or spreadsheets on a schedule.
  • Serve fast extracts of Hadoop-resident tables to operational databases and SaaS tools through Impala instead of slow batch engines.

Analytics on eClinicalWorks's data

Records and events from eClinicalWorks land in Apache Impala as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

Combine eClinicalWorks's data with data from every other synced system to answer questions no single tool can.

Where eClinicalWorks accepts updates: operational write-back

Segments, scores, or reference values computed in Apache Impala sync back onto records in eClinicalWorks, putting analysis where the work happens.

What you can sync between Apache Impala and eClinicalWorks

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 eClinicalWorks objects
External Tables Tables over files loaded by other tools, queryable without data movement. Appointments Scheduling records available via FHIR and HL7 SIU messages, synced for reminders and outreach.
Users and Roles Principals (often via Ranger/Sentry) used to grant scoped read access. Encounters Visit records tying diagnoses, providers, and billing context together.
Databases Namespaces shared with the Hive Metastore that scope tables. Practitioners Provider records used to keep directories and scheduling systems consistent.
Tables HDFS or object-storage backed tables (commonly Parquet) read at interactive speed. Observations Labs and vitals, delivered via FHIR resources or HL7 ORU result messages.
Partitions Partition values used to limit scans and drive incremental reads. Medications Prescription and medication-list data within the patient record.
Views Logical views readable as modeled sources. Allergies Allergy and intolerance entries in the clinical record.

How the Apache Impala and eClinicalWorks 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

Rate limits
No API quotas; concurrency is bounded by cluster resources and admission control settings

eClinicalWorks

Integration surface
FHIR R4 REST API plus HL7 v2 interfaces (ADT, SIU, ORU) through an interface engine
Authentication
OAuth 2.0 / SMART on FHIR for the FHIR API; site-configured credentials for HL7 interface connections
Change detection
HL7 interface feeds push event messages as they occur; the FHIR API is polled
Capabilities
