Connectors

Any source, any target, one proof.

Every connector computes the same SHA-256 based fingerprint inside its own engine, byte-verified against a reference implementation and against every other engine, so a comparison across engines is as exact as one within an engine. Where an engine cannot compute the proof in SQL, the reference path takes over and says so.

Dataset engines

Active today.

Active means the cross-engine comparison tests are complete and byte-verified, and the connector is selectable without a badge. Readiness is published per connector in the documentation and never softened for a sale.

SystemReadinessNotes
PostgreSQL 14+, Aurora PostgreSQLActiveNative proof pushdown; bulk key extraction over server-side cursors.
MySQL 8.0+, Aurora MySQLActiveNative proof pushdown.
Microsoft SQL Server 2019+ActiveNative proof pushdown over UTF-8 collation; earlier versions use the reference path.
Oracle DatabaseActiveNative SHA-256 proof through DBMS_CRYPTO; a weaker fallback is flagged as advisory, never silently used.

SAP HANAActiveNative SHA-256 proof over UTF-8; the usual target of SAP replication.

Replication tools

CDC-aware readiness.

You declare the replication tool between a source and a target; Paridity never guesses it. With a Tier-1 adapter, readiness consults the tool's own state, lag and stability before a window is fixed, so a run never compares against replication that is still in flight. Without a tool, Paridity still aligns the window from watermarks, control markers, partitions or snapshots.

ToolReadinessWhat Paridity reads
DebeziumActiveKafka Connect REST: connector state and the replicated table list.
AirbyteActiveREST API: sync state and the replicated streams.
FivetranActiveREST API: connector sync completion and the replicated tables.

SAP and other systems without a change timestamp

Many SAP tables carry no universal last-change timestamp, and a posting date is not one. Paridity never infers freshness from a business date. It uses replication metadata, SAP-native change sources, validated table-specific rules, or an explicit snapshot mode, declared per mapping and reviewed at onboarding.
