Seed + Stream

Copy the starting state without losing what changes during the copy.

SQL Flow pins a source position, plans parallel table slices, records durable completion, and streams the overlap into the same destination pipeline.

The job to be done

Move committed data with a path your team can explain.

A capability matters when it removes an operational decision, not when it adds another checkbox. SQL Flow connects source-aware capture, durable progress, target apply, and validation so the page you are reading leads to a usable operating path.

PostgreSQL can share an exported snapshot. Other paths combine a pinned log position, replay-safe overlap, durable markers, and idempotent apply. SQL Flow handles position pinned before data copy; parallel ranges with bounded concurrency; durable per-table completion markers; resume without restarting completed tables.

Why this path matters

Use the strongest snapshot primitive each engine exposes.

PostgreSQL can share an exported snapshot. Other paths combine a pinned log position, replay-safe overlap, durable markers, and idempotent apply. SQL Flow handles position pinned before data copy; parallel ranges with bounded concurrency; durable per-table completion markers; resume without restarting completed tables.

What changes for you

SQL Flow can inspect the source, describe the expected target, create compatible tables and keys, and journal optional index work. SQL Flow handles target schema check and create; PostgreSQL binary COPY acceleration; generic heterogeneous loading; confirmed reload and position reset.

The outcome

Bring table sizes, keys, source constraints, and target engine. We will select slicing, overlap, and catch-up.

The payoff

See what the capability changes.

Pinned

CDC handoff

Capture starts at a named position before copying.

Parallel

Bounded workers

Large tables are sliced without unbounded pressure.

Visible

Progress and ETA

Track rows, rate, and completion per table.

Where the work happens

The details that make the result usable.

Read each capability as part of the operating path. The important question is not whether a feature exists, but what work it removes and what evidence it leaves behind.

Source-aware consistency

Use the strongest snapshot primitive each engine exposes.

PostgreSQL can share an exported snapshot. Other paths combine a pinned log position, replay-safe overlap, durable markers, and idempotent apply.

SQL Flow handles position pinned before data copy; parallel ranges with bounded concurrency; durable per-table completion markers; resume without restarting completed tables.

  • Position pinned before data copy
  • Parallel ranges with bounded concurrency
  • Durable per-table completion markers
  • Resume without restarting completed tables

Prepare the target

Review schema and ingestion before loading.

SQL Flow can inspect the source, describe the expected target, create compatible tables and keys, and journal optional index work.

SQL Flow handles target schema check and create; PostgreSQL binary COPY acceleration; generic heterogeneous loading; confirmed reload and position reset.

  • Target schema check and create
  • PostgreSQL binary COPY acceleration
  • Generic heterogeneous loading
  • Confirmed reload and position reset

Before you choose

Check the path against your environment.

Use the page-specific details below as a short discovery checklist. They are the conditions and work areas that shape the capability, not generic product promises.

  • Position pinned before data copy
  • Parallel ranges with bounded concurrency
  • Durable per-table completion markers
  • Resume without restarting completed tables
  • Target schema check and create
  • PostgreSQL binary COPY acceleration

The path to confidence

See the work. Make the call. Prove the result.

The page keeps the product detail close to the decision it supports. Your team can see what the software handles automatically, what it changes for the target, and what the result leaves ready to operate.

Take the next useful step.

A capability becomes easier to operate when the next decision follows from the constraint you just uncovered. Explore the related work that completes this part of the path.
