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.

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.

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

Compress the relay

Move more data across the WAN.

SQL Flow compresses relay data 5x, reducing the bytes sent between environments and speeding transfers across constrained WAN links.

✓5x smaller relay payloads
✓Faster WAN transfer
✓Offset-resumable shipping
✓Independent restart of either half

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.
