19 results for “Value Streams”
Reactive Streams
A specification for asynchronous stream processing in which the consumer requests a specific number of items, making backpressure part of the protocol rather than an afterthought.
Value Stream
The end-to-end sequence of activities that delivers a result to a customer, viewed across whatever departments and systems it happens to cross.
Application Portfolio Management
Maintaining an inventory of every application with its owner, cost, business value and technical health, and using it to decide what to invest in, replace or retire.
Event Store
An append-only store of domain events organised into per-entity streams, serving as the system of record rather than as a log beside it.
Eventual Consistency
A guarantee that replicas will converge to the same value if updates stop, with no bound on how long reads may be stale.
Foreign Key Constraint
A database-enforced rule that a referencing value must exist in the referenced table — referential integrity that no application bug can violate.
Idempotency Key
A client-generated unique value sent with a request so the server can recognise a retry and return the original result instead of acting twice.
Log Compaction
A retention policy that keeps only the most recent value for each key rather than deleting by age, so the log becomes a durable snapshot of current state.
Product Thinking
Treating what you build as something with users, a value proposition and a lifecycle, rather than as a project that completes.
Security vs Usability
A trade-off that is usually resolved by varying the control with the value of the action, rather than by choosing a uniform level of friction.
Structured Logging
Emitting log entries as machine-parseable key-value records rather than as formatted prose.
Surrogate Key
A system-generated identifier with no business meaning, used as the primary key instead of a naturally occurring business value.
Target Tracking Scaling
An autoscaling policy that adds or removes capacity to hold a chosen metric near a target value, like a thermostat, rather than reacting to threshold breaches.
Tokenisation
Replacing a sensitive value with a non-sensitive surrogate, with the mapping held in one tightly-controlled vault.
Value Streams
End-to-end delivery of an outcome, and where the waiting happens.
Cloud Databases
Managed relational, key-value, document and analytical services.
NoSQL Stores
Key-value, document, wide-column and graph — what each buys and forbids.
Security vs Usability
Varying control by the value of the action rather than uniformly.
