Optimisation, Migration & Quality

ETL performance optimisation

When the overnight load no longer fits the overnight window, the cause is usually a handful of steps, not the whole process. We profile ETL runtimes, find the bottlenecks and fix them — often with set-based rewrites and better load design rather than bigger hardware.

When teams bring us in

Signs you need ETL Optimisation support

  • Loads finish later every month and now overlap business hours
  • One package or procedure dominates total runtime
  • Row-by-row cursors or lookups process millions of rows
  • Failures late in the run force a full restart

What's included

Our ETL Optimisation work

  • 01

    Runtime profiling

    Step-level timings from SQL Agent, SSISDB and logging to see exactly where time goes.

  • 02

    Bottleneck fixes

    Set-based T-SQL, better SSIS data-flow design, indexing and incremental logic.

  • 03

    Dependency re-planning

    Re-ordering and parallelising independent loads to shorten the critical path.

  • 04

    Ongoing baselines

    Runtime and volume baselines so future regressions are spotted early.

FAQ

ETL Optimisation — common questions

Do you need access to production to optimise ETL?
We need execution history and representative data volumes. Much of the analysis can use SQL Agent and SSISDB history plus a production-like test environment.
Will optimisation change our results?
It shouldn't. Every change is reconciled against existing outputs before it is deployed.
Is ETL optimisation (or optimization) a one-off project?
The fixes are one-off, but we recommend keeping runtime baselines and monitoring in place so performance doesn't drift back.
