Why teams connect Apache Pinot and Bill

Land the financial records from Bill in Apache Pinot continuously, and write results back, without building or maintaining a pipeline.

Finance data belongs in the warehouse: revenue, invoices, payments, and customers joined with everything else the business measures. Getting it there usually means an extraction pipeline that breaks quietly and delivers yesterday's numbers.

Stacksync syncs Bank Accounts, Vendor Credits and Credit Memos, Bills, Vendors from Bill into tables in Apache Pinot in real time, and the connection works in both directions: values computed in Apache Pinot can be written back to fields in Bill where you want them operational. Schema changes are handled, API limits are managed, and the sync is something you configure rather than code you maintain.

Common use cases

  • 01 Read Payments and payment status into a reconciliation database once bills are marked paid in BILL.
  • 02 Read approved Bills and their line items into a Postgres warehouse for spend, accrual, and cash-flow reporting without CSV exports.
  • 03 Keep upsert-enabled real-time tables aligned with mutable operational records streamed from source systems.
  • 04 Query per-account usage metrics from Pinot and sync them into CRM fields so sales sees product activity.

Common sync patterns

Write-back of computed fields

Scores or segments computed in Apache Pinot, like payment-risk flags or customer tiers, sync back onto records in Bill where the finance team can act on them.

Queryable history for audit and reconciliation

A continuously synced copy in Apache Pinot gives you a durable, queryable record of financial data for month-end and audit questions.

Finance analytics without ETL

Invoices, payments, and customer records from Bill arrive in Apache Pinot as queryable tables, current within seconds instead of a day behind.

What you can sync between Apache Pinot and Bill

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 Pinot objects Bill objects How this pairing syncs
Indexes Inverted, range, and star-tree indexes that determine which sync queries run at low latency. Payments Outgoing vendor payments and received customer payments; read for reconciliation and created to schedule bill pay. Indexes is specific to Apache Pinot and Payments to Bill — each maps to any object or custom field on the other side.
Tenants Logical groupings that isolate workloads on shared clusters. Chart of Accounts GL accounts used to code bills and invoices; typically mastered in the accounting system and written into BILL for consistent coding. Tenants is specific to Apache Pinot and Chart of Accounts to Bill — each maps to any object or custom field on the other side.
Tables The queryable unit, defined as offline, real-time, or hybrid; the main read target. Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. Tables is specific to Apache Pinot and Bank Accounts to Bill — each maps to any object or custom field on the other side.
Schemas Column definitions (dimensions, metrics, time columns) mapped during integration setup. Vendor Credits and Credit Memos AP and AR adjustments applied against bills and invoices; synced so balances stay accurate on both sides. Schemas is specific to Apache Pinot and Vendor Credits and Credit Memos to Bill — each maps to any object or custom field on the other side.
Segments Immutable data files that batch ingestion uploads and the cluster serves. Bills Accounts-payable amounts owed to vendors, with bill line items; read and created via /v3/bills and pulled incrementally by filtering on createdTime/updatedTime. Segments is specific to Apache Pinot and Bills to Bill — each maps to any object or custom field on the other side.
Real-time Tables Tables fed continuously from streams like Kafka, including upsert-enabled tables. Vendors Payee master records; synced two-way with vendor/supplier tables in an ERP or accounting system so new payees don't have to be re-keyed. Real-time Tables is specific to Apache Pinot and Vendors to Bill — each maps to any object or custom field on the other side.

How changes propagate between Apache Pinot and Bill

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 Pinot Bill Interval-based propagation

DetectionStacksync polls Apache Pinot for changes on an incremental schedule, reading only records changed since the previous pass. Data enters Pinot via streaming ingestion or segment upload, not row-level writes.

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

Bill Apache Pinot Sub-second propagation

DetectionBill notifies Stacksync of record changes through webhook events. Webhook event subscriptions (POST /v3/subscriptions) for bills, vendors, payments, invoices, and bank accounts, with polling on.

DeliveryEach detected change is applied to Apache Pinot as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Apache Pinot: No fixed API quotas; query throughput depends on broker and server sizing.
  • Bill: 20,000 requests per developer key per hour; login (POST /v3/login) capped at 200/hour; maximum 3 concurrent requests per developer key per organization. Spend & Expense API is a separate token at 60 calls/token/minute.
