Getlocalidd

Getlocalidd is a term used in software development to denote a function or method that retrieves the local identifier (local ID) from a larger, often global, identifier. It is not tied to a single standard API; rather, multiple codebases implement a function with a similar purpose to enable local context mapping, partitioning, or resource scoping within a system.

In practice, a global or composite ID may embed locality information such as a node, shard, namespace, or tenant. The getlocalidd function extracts the portion of the ID that is meaningful within the local scope of a service or process. The exact extraction logic varies by implementation and ID format, but common patterns include parsing a delimited string, decoding a structured binary ID, or applying bitwise operations to isolate the local segment.

Typical use cases include routing and sharding decisions, local caching keys, and resource bookkeeping in distributed databases or microservice architectures. When used correctly, getlocalidd helps map a globally unique object to a locally manageable resource, facilitating efficient lookups and isolation. Important considerations include ensuring a deterministic extraction method, avoiding collisions, and recognizing that the function’s behavior depends on the ID schema chosen by the system. It is also important to distinguish getlocalidd from similarly named functions that may retrieve different components of an identifier or operate on different namespaces.

Example: if a global ID uses the format "node-localID", getlocalidd("node42-12345") might return "12345". Actual behavior depends on the specific project’s ID schema.
