Two-way sync
Changes in Lemlist or VoltDB instantly reflect in both systems. No stale data, no manual imports.
Keep Lemlist and VoltDB in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Engineers integrate with tools like Lemlist through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in VoltDB.
Stacksync mirrors Leads, Activities, Unsubscribes, Webhooks from Lemlist into Partitioned Tables, Replicated Tables, Stored Procedures, Materialized Views in VoltDB and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Lemlist, so the tool and the database never disagree.
Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.
Records from Lemlist are ordinary rows in VoltDB; join them, index them, and use them in application logic without touching the vendor API.
Write to the synced tables in VoltDB and Stacksync propagates the change into Lemlist, replacing custom integration code.
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.
| Lemlist objects | VoltDB objects | |
|---|---|---|
| Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target. | |
| Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data. | |
| Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | Stored Procedures Precompiled transactional units that serve as the primary write interface. | |
| Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources. | |
| Team Members Sender and seat records map outreach activity to reps in other systems. | Streams Insert-only constructs that feed the export subsystem with committed rows. | |
| Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks. |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Lemlist–VoltDB connection.
Changes in Lemlist or VoltDB instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Lemlist or VoltDB data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Lemlist or VoltDB record.
Track your Lemlist ⇄ VoltDB sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Lemlist and VoltDB.
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.
Authenticate Lemlist and VoltDB with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Lemlist and VoltDB objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Lemlist and VoltDB: authenticate both systems, choose the objects to sync (such as Lemlist's Leads and Activities), map fields visually, and changes propagate both ways in milliseconds — no code required.
Change detection on Lemlist: Webhooks on outreach activity events, plus polling. 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 Lemlist side: Leads, Activities, Unsubscribes, Webhooks, plus custom fields where Lemlist exposes them. On the VoltDB side: Partitioned Tables, Replicated Tables, Stored Procedures, Materialized Views. 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 Lemlist and VoltDB: One integration pattern for the whole stack; Read Lemlist with a query; Automate Lemlist from your codebase. Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.
Lemlist: REST API. Authentication: API key. VoltDB: SQL over JDBC plus native client libraries and an HTTP/JSON interface. Authentication: Database credentials. Stacksync manages authentication, retries, and rate limits on both sides.
