exonware-xwnode 0.9.0.17

Node-based data processing and graph computation library

xwnode

Graph-shaped data with one API: many node and edge strategies, lots of query languages behind the same surface, and AUTO when you want the implementation chosen for you.

Longer write-up: README_LONG.md.

Install

Install	What you get	When to use
pip install exonware-xwnode	Lite - core only	Smallest install.
pip install exonware-xwnode[lazy]	Lazy - backends pulled in when first used	Local dev.
pip install exonware-xwnode[full]	Full - common strategies pre-installed	CI or production bundles.

Requires xwsystem. Extras only add dependencies; the import path stays the same.

---

Quick start

from exonware.xwnode import XWNode

node = XWNode.from_native({
    'users': [{'name': 'Alice', 'age': 30, 'city': 'NYC'}, {'name': 'Bob', 'age': 25, 'city': 'LA'}],
    'products': {'laptop': {'price': 1000}, 'phone': {'price': 500}}
})

print(node['users'][0]['name'].value)   # Alice
results = node.query("SELECT * FROM users WHERE age > 25")
node.add_edge('Alice', 'Bob', {'relationship': 'friend'})
friends = node.neighbors('Alice')

Pick a mode explicitly (NodeMode.HASH_MAP, NodeMode.LSM_TREE, EdgeMode.COMPRESSED_GRAPH, EdgeMode.HNSW, …) or use NodeMode.AUTO. See REF_14_DX and REF_15_API.

What you get

Area	Contents
Node strategies	Hash maps, ordered structures, LSM-style trees, tries, learned indexes, and more behind one API.
Edge strategies	Adjacency, compressed graphs, HNSW, R-tree, quadtree, temporal layouts, …
Query	Many languages (SQL, GraphQL, Cypher, XPath, …) via xwquery.
Operations	WAL, Bloom filters, lock-free options, automatic strategy selection where enabled.

Status and roadmap: REF_22_PROJECT. Full strategy lists: REF_15_API, docs/.
