Detected signals

Transaction flow

The SQL flow includes transaction boundaries.

Map every read/write inside the transaction and verify rollback behavior.

Write operation

The flow changes data or schema.

Check affected rows, constraints, triggers, migrations, and backup/rollback plan.

Deadlock or lock wait

Lock contention is part of the failure.

Identify lock order, long transactions, and competing statements.

Read dependency

The flow includes reads that may drive writes or locks.

Check read predicates, isolation level, and stale assumptions.

DebugTools product

SQL Flow

SQL Flow is a focused DebugTools mini-product for developers. Turn SQL statements and logs into execution flow, dependency, lock, transaction, and migration-risk notes.

Use cases

  • Inspect CI, Kubernetes, trace, SQL, JVM, and production incident signals.
  • Move from noisy output to the next command or measurement to run.
  • Create an investigation note that is easy for teammates to follow.

How it works

  • Paste or load the snippet you want to inspect in SQL Flow.
  • Run the tool in the browser and review the highlighted output.
  • Copy, export, or turn the result into the next debugging step.

Privacy

  • SQL Flow is local-first. The core workflow runs in your browser and does not require sending pasted content to DebugTools servers.
