Why teams connect Apache Cassandra and Paylocity

Put your workforce data where your apps can reach it: Apache Cassandra and Paylocity share the same people, positions, and org structure in real time.

Paylocity is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. Apache Cassandra is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Deductions (Pay Setup), Earnings (Pay Setup), Local and State Taxes, Direct Deposit in Paylocity need to exist as queryable Counters, Keyspaces, Tables, Partitions and Rows in Apache Cassandra before an app can act on them. When that bridge is a nightly export or a hand-run CSV, every downstream system spends the day working from a roster that has already moved on.

Stacksync syncs Counters, Keyspaces, Tables, Partitions and Rows in Apache Cassandra with Deductions (Pay Setup), Earnings (Pay Setup), Local and State Taxes, Direct Deposit in Paylocity field by field, in real time. You decide which system owns which fields — Paylocity typically owns identity and org attributes, while operational or computed values can flow back the other way — and Stacksync keeps every copy consistent, matching records on a stable key and resolving conflicts by rules you set.

The result is one live picture of the workforce on both sides: HR keeps its source of truth, and the database keeps a current mirror that internal apps, reports, and access controls can trust without a batch window in between.

Common use cases

  • 01 Feed Cassandra change streams into search indexes or caches that must track the source of truth.
  • 02 Consolidate data from multiple keyspaces or clusters into one reporting store.
  • 03 Push hired candidates from an ATS into Paylocity via the Onboarding endpoint, then read Onboarding Status to confirm the record before the first payroll run.
  • 04 Upsert recurring Deductions and Earnings on employee records when benefits or 401(k) elections change in a benefits admin system, without re-keying payroll setup.

Common sync patterns

Reporting and analytics on current data

Deductions (Pay Setup), Earnings (Pay Setup), Local and State Taxes, Direct Deposit replicate into Apache Cassandra where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

Org and structure stay aligned

Groups, departments, managers, and reporting lines from Paylocity stay consistent in Apache Cassandra, so hierarchy-driven logic and permissions don't drift.

Computed and operational fields flow back

Values assembled or corrected in Apache Cassandra write onto the matching record in Paylocity where those fields are writable, keeping the people system enriched.

What you can sync between Apache Cassandra and Paylocity

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 Cassandra objects Paylocity objects How this pairing syncs
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Custom Fields Read-only company-specific custom fields returned by category, used to enrich the employee record downstream. Secondary Indexes is specific to Apache Cassandra and Custom Fields to Paylocity — each maps to any object or custom field on the other side.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Employees Core HR record keyed by companyId + employeeId; two-way via Create New Employee (POST) and Update Employee (PATCH), plus Get Employee / Get All Employees for reads. User-Defined Types is specific to Apache Cassandra and Employees to Paylocity — each maps to any object or custom field on the other side.
Collections List, set, and map columns handled with type-aware field mapping. Onboarding Create Employee Onboarding pushes new-hire data into Paylocity's onboarding workflow; Get Onboarding Status reads back partner onboarding progress. Write-in for hires from an ATS. Collections is specific to Apache Cassandra and Onboarding to Paylocity — each maps to any object or custom field on the other side.
Counters Increment-only counter columns, usually read-only in syncs. Deductions (Pay Setup) Recurring deduction codes at the employee level; two-way via Upsert Deduction and Delete, with Get Deduction / Get All Deductions for reads. Counters is specific to Apache Cassandra and Deductions (Pay Setup) to Paylocity — each maps to any object or custom field on the other side.
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Earnings (Pay Setup) Recurring earning codes at the employee level; two-way via Upsert Earning and Delete, with Get All Earnings and Get by earning code for reads. Keyspaces is specific to Apache Cassandra and Earnings (Pay Setup) to Paylocity — each maps to any object or custom field on the other side.
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Local and State Taxes Two-way via Create/Update/Delete Local Tax and Upsert Primary / Non-Primary State Tax; Get by tax code and Get All for reads. Tables is specific to Apache Cassandra and Local and State Taxes to Paylocity — each maps to any object or custom field on the other side.

How changes propagate between Apache Cassandra and Paylocity

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.

Apache Cassandra Paylocity Sub-second propagation

DetectionChanges in Apache Cassandra are captured at the source via change data capture — no polling loop against its API. Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns.

DeliveryEach detected change is written to Paylocity through its API, with automatic retries and rate-limit backoff.

Paylocity Apache Cassandra Sub-second propagation

DetectionPaylocity notifies Stacksync of record changes through webhook events. Webhooks — Paylocity POSTs Employee New Hire, Employee Change, Termination, Payroll Processed, and Time Off Approval events to a callback URL.

DeliveryEach detected change is written to Apache Cassandra through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apache Cassandra: No API quotas; throughput is governed by cluster capacity and consistency-level choices.
  • Paylocity: 25 requests per second (1,500 per minute); exceeding it returns HTTP 429. Every path is scoped to a Paylocity-assigned companyId (a company code, not a UUID).

Change detection
Webhooks — Paylocity POSTs Employee New Hire, Employee Change, Termination, Payroll Processed, and Time Off Approval events to a callback URL; payloads carry only companyId and employeeId, so the receiver calls the relevant API to fetch changed values. Scheduled polling is used for objects without webhooks.
