Operational Data Push
Sending modelled analytical data back into operational tools, which turns a warehouse table into a production dependency with none of the guarantees.
ETL vs ELT
Whether data is transformed before loading into the target or after it, which decides where the compute happens and how much raw history you keep.
Reverse Proxy
A server that receives client requests on behalf of one or more backends, forwarding them and returning the response.
Backfill
Re-running a pipeline over historical periods to populate new data or correct a past error, and the operation that proves whether a pipeline is well designed.
Idempotent Pipeline
A pipeline whose task can be re-run for the same input window any number of times and produce the same result.
Pipeline Orchestration
Coordinating the execution of data tasks by dependency rather than by clock, with retries, backfill and observability built in.
Proxy Buffering
Whether a reverse proxy accumulates a response before forwarding it, which protects the backend from slow clients but breaks streaming.
X-Forwarded-For
The header chain recording original client addresses through a series of proxies — and a value that must never be trusted without knowing the topology.
A warehouse table now feeds the CRM through reverse ETL. It breaks, and the analytics team and the CRM team each say it is the other's problem. How do you resolve it?
The dispute is a design gap, not a personality problem A warehouse table built for analysis — nightly latency, best effort availability, schema changes made by
A nightly pipeline failed halfway and the retry produced duplicate rows. Walk me through fixing this properly.
The immediate problem The task appends rather than replacing its window , so a partial run followed by a retry writes some rows twice. The data is now wrong in
