Pelias Database Client

`pelias-dbclient` is a core Node.js module within the Pelias geocoder ecosystem, providing a stream-based interface for efficiently bulk-inserting documents into Elasticsearch. Its primary function is to act as a crucial pipeline stage for Pelias import processes, transforming Pelias `Document` objects into Elasticsearch-compatible bulk operations. The current stable version is v3.3.0, with releases occurring on a feature-driven, rather than strict time-based, cadence, though a major version (v3.0.0) was released in March 2024. Key differentiators include its tight integration with the Pelias data model, its focus on streaming for large-scale data ingestion, and its commitment to open-source principles as part of the broader Pelias open-data geocoding project. It leverages the official `elasticsearch` client under the hood and is designed specifically for Node.js environments.
