Hybrid and cloud replication

Keep log access on the LAN. Move compressed changes across the WAN.

Place a capture agent beside the database and an apply agent beside cloud destinations. A durable spool-to-spool relay absorbs outages and resumes from the remote durable offset.

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.

The control plane presents one pipeline while each half reports its own health, lag, spool depth, and resource use. SQL Flow handles independent capture and apply assignment; HMAC-authenticated relay with optional TLS; adaptive container sizing and compression; rate and in-flight window limits.

Why this path matters

Capture and apply can live on different agents.

The control plane presents one pipeline while each half reports its own health, lag, spool depth, and resource use. SQL Flow handles independent capture and apply assignment; HMAC-authenticated relay with optional TLS; adaptive container sizing and compression; rate and in-flight window limits.

What changes for you

When the link is unavailable, the capture cursor parks and the local spool grows within policy. Reconnect continues from the apply spool durable head. SQL Flow handles offset-resumable shipping; idempotent remote ingest; backlog size and drain ETA; independent restart of either half.

The outcome

Tell us where the systems run and what the network permits. We will map agents, relay, security, and backlog.

The payoff

See what the capability changes.

LAN

Local capture

Log reads and schema queries stay near the source.

WAN

Resumable relay

Only compressed change containers cross the link.

Cloud

Local apply

Destination batching runs close to its targets.

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.

Split the pipeline

Capture and apply can live on different agents.

The control plane presents one pipeline while each half reports its own health, lag, spool depth, and resource use.

SQL Flow handles independent capture and apply assignment; HMAC-authenticated relay with optional TLS; adaptive container sizing and compression; rate and in-flight window limits.

  • Independent capture and apply assignment
  • HMAC-authenticated relay with optional TLS
  • Adaptive container sizing and compression
  • Rate and in-flight window limits

Outages land on disk

Do not make the source log wait for the WAN.

When the link is unavailable, the capture cursor parks and the local spool grows within policy. Reconnect continues from the apply spool durable head.

SQL Flow handles offset-resumable shipping; idempotent remote ingest; backlog size and drain ETA; independent restart of either half.

  • Offset-resumable shipping
  • Idempotent remote ingest
  • Backlog size and drain ETA
  • Independent restart of either half

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.

  • Independent capture and apply assignment
  • HMAC-authenticated relay with optional TLS
  • Adaptive container sizing and compression
  • Rate and in-flight window limits
  • Offset-resumable shipping
  • Idempotent remote ingest

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.

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.
