Why teams connect Splunk and VoltDB
Give Splunk the users, events, and records that live in VoltDB in real time, and sync the cohorts and scores Splunk computes back into VoltDB where your applications read them.
A database holds the rows your business runs on: the users, events, orders, and records that every service reads and writes. Splunk is where people make sense of them, as dashboards, funnels, cohorts, and metrics. Moving the data from VoltDB into Splunk usually means a hand-built extract or a change-data-capture pipeline that breaks the moment a column is renamed, and reporting that always trails last night's load.
Stacksync syncs Replicated Tables, Stored Procedures, Materialized Views, Streams in VoltDB with Fired Alerts, KV Store Collections, Indexes, HTTP Event Collector in Splunk in real time and in both directions. Operational rows flow into Splunk as they change, so dashboards read current data with no pipeline to maintain, and the segments, cohorts, or scores Splunk computes flow back into VoltDB, where the applications and services that read from it get them at normal query latency. Field-level mapping, schema and type translation, and conflict resolution are handled for you.
Common use cases
- 01 Ingest application, CRM, or database records into Splunk via the HTTP Event Collector so operational data lands alongside logs for correlation and dashboards.
- 02 Read and write KV Store collections to keep Splunk lookups — asset inventories, allow/deny lists, enrichment tables — in sync with an external source of truth in both directions.
- 03 Keep product, plan, or entitlement state consistent between VoltDB and back-office systems.
- 04 Push aggregates from VoltDB materialized views into dashboards or operational tools.
Common sync patterns
Filter and grouping dimensions kept fresh
Attributes teams slice by, such as plan, region, or account owner, stay current in Splunk because they sync from VoltDB as they change, instead of going stale after a one-time import.
Where Splunk tracks product events: behavior onto stored records
Signup, usage, and lifecycle events captured in Splunk sync into VoltDB as rows, so applications and internal tools can read behavioral data next to the records they already keep.
Where Splunk builds cohorts or scores: results your services can read
Segments, cohorts, or scores computed in Splunk sync back into VoltDB, where the services that read from the database act on them at query speed without calling the analytics API.
What you can sync between Splunk and VoltDB
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.
| Splunk objects | VoltDB objects | How this pairing syncs | |
|---|---|---|---|
| KV Store Collections App-scoped, MongoDB-backed key-value collections at /servicesNS/{owner}/{app}/storage/collections/data/{collection} with full CRUD and batch endpoints. Genuinely bidirectional lookup/state store — read records out or write records in. | Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources. | KV Store Collections is specific to Splunk and Materialized Views to VoltDB — each maps to any object or custom field on the other side. | |
| Indexes Index inventory and settings (retention, max size, event counts) via /services/data/indexes, with create and edit; loaded into a database for capacity, retention, and data-onboarding tracking. | Streams Insert-only constructs that feed the export subsystem with committed rows. | Indexes is specific to Splunk and Streams to VoltDB — each maps to any object or custom field on the other side. | |
| HTTP Event Collector The write-in path: POST events and metrics to /services/collector (port 8088, or 443 on Splunk Cloud) authenticated with a per-input HEC token, so external records are indexed alongside logs for search and correlation. | Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks. | HTTP Event Collector is specific to Splunk and Export Targets and Topics to VoltDB — each maps to any object or custom field on the other side. | |
| Users and Roles Accounts at /services/authentication/users and role/capability definitions at /services/authorization/roles, with full CRUD; exported for access reviews or provisioned from an identity source of truth. | Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target. | Users and Roles is specific to Splunk and Partitioned Tables to VoltDB — each maps to any object or custom field on the other side. | |
| Dashboards Simple XML dashboard and view definitions at /servicesNS/{owner}/{app}/data/ui/views; exported for backup and audit, or created and updated programmatically from version control. | Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data. | Dashboards is specific to Splunk and Replicated Tables to VoltDB — each maps to any object or custom field on the other side. | |
| Search Results SPL searches dispatched via POST /services/search/jobs return a search ID (SID); results are pulled from /services/search/jobs/{sid}/results once the job completes, or synchronously via oneshot/export mode. The primary read path for streaming indexed events out to a warehouse. | Stored Procedures Precompiled transactional units that serve as the primary write interface. | Search Results is specific to Splunk and Stored Procedures to VoltDB — each maps to any object or custom field on the other side. |
How changes propagate between Splunk and VoltDB
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.
Splunk VoltDB Sub-second propagation
DetectionSplunk notifies Stacksync of record changes through webhook events. Time-range searches over indexed events (earliest/latest on _time or _indextime).
DeliveryEach detected change is applied to VoltDB as a row-level write, with types converted between the two schemas.
VoltDB Splunk Interval-based propagation
DetectionStacksync polls VoltDB for changes on an incremental schedule, reading only records changed since the previous pass. Export streams and topics push committed changes to configured targets.
DeliveryEach detected change is written to Splunk through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Splunk: The management REST API throttles through search-concurrency quotas — max concurrent searches per user and role, plus per-CPU historical search limits in limits.conf — rather than a fixed per-request rate; exceeding quota queues or blocks jobs. HEC has per-token and per-instance throughput limits, and Splunk Cloud adds ingestion and API limits on top.
- VoltDB: No API rate limits; throughput is bounded by partition count and cluster sizing.

How the Splunk and VoltDB connectors work
Splunk
- Integration surface
- REST API (management API + HTTP Event Collector)
- Authentication
- HTTP Basic (username/password), or a session key from POST /services/auth/login sent as Authorization: Splunk <key>, or a bearer authentication token (Authorization: Bearer <token>). The HTTP Event Collector uses its own per-input token (Authorization: Splunk <hec-token>). Management API defaults to port 8089; HEC to port 8088 (443 on Splunk Cloud).
- Change detection
- Time-range searches over indexed events (earliest/latest on _time or _indextime); events are immutable once indexed, so incremental extraction advances a time cursor rather than a modified-date CDC feed. Config objects such as saved searches and KV Store are polled; alerts can push via a saved-search webhook action.

FAQ
Splunk and VoltDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Splunk and VoltDB: authenticate both systems, choose the objects to sync (such as Splunk's KV Store Collections and Indexes), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Change detection on Splunk: Time-range searches over indexed events (earliest/latest on _time or _indextime); events are immutable once indexed, so incremental extraction advances a time cursor rather than a modified-date CDC feed. Config objects such as saved searches and KV Store are polled; alerts can push via a saved-search webhook action. On VoltDB: Export streams and topics push committed changes to configured targets; otherwise polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Splunk side: Fired Alerts, KV Store Collections, Indexes, HTTP Event Collector, plus custom fields where Splunk exposes them. On the VoltDB side: Replicated Tables, Stored Procedures, Materialized Views, Streams. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Splunk and VoltDB: Filter and grouping dimensions kept fresh; Where Splunk tracks product events: behavior onto stored records; Where Splunk builds cohorts or scores: results your services can read. Attributes teams slice by, such as plan, region, or account owner, stay current in Splunk because they sync from VoltDB as they change, instead of going stale after a one-time import.
