Connection Profiling is a read-only check on any connection. Zwiron inspects the database and shows what you need before you sync — size, encryption, and optional recommendations. It does not create a pipeline or modify your data.

​
What you see on the Profile tab

Zwiron still detects connector capabilities and picks the best read/write strategies in the background when you create a Job. Those internals are not shown on the Profile tab.

​
How to run a profile

  1. Go to Connections → open a connection → Profile
  2. Click Run Profile (or Refresh if one already exists)
  3. Review Size & health and any Recommendations
Profiling has a 55-second timeout. Large databases may return partial metadata within that window.

​
Profiling and pipeline creation

When you create a new Job, Zwiron may run a lightweight profile in the background to:
  • Discover tables (so you can select them)
  • Detect which sync modes are available
  • Choose the best read and write strategies automatically
On Hosted connections the check runs from Zwiron’s infrastructure; on Agent connections it runs through your agent.

​
Recommendations

When something useful is missing (for example CDC / logical replication on PostgreSQL), Profile shows a Recommended or Suggested tip with:
  • Why it matters in plain language
  • Optional expand for exact commands and safety notes
Example (PostgreSQL):

​
Security

Profiling is read-only. It uses SELECT and system catalog queries only — it never writes to your database during a profile run.
