This release is a pre-release and may not be stable for production use.
houyidb — HouyiDB Python SDK
HouyiDB collections HTTP API 的薄封装：传输 + 类型，不含框架语义。
from houyidb import HouyiClient, Vector, Filter
client = HouyiClient("http://127.0.0.1:7000")
col = client.collection("goods") # 首次 upsert 时隐式创建
col.upsert([
Vector(id=1, values=[0.9, 0.1], payload={"name": "apple", "price": 3.5}),
Vector(id=2, values=[0.1, 0.9], payload={"name": "laptop", "price": 8999}),
])
res = col.hybrid_search(
[0.85, 0.15], k=3,
filters=[Filter("price", "lt", 1000)],
include_payload=True,
)
for hit in res.hits:
print(hit.id, hit.score, hit.payload)
col.delete([1]) # 按 id
col.delete(filters=[Filter("price", "lt", 100)]) # 按条件（标量页求值，刚写入即可命中）
契约要点
- 相似度分数：
1 - cosine_distance，越大越相似（余弦后端）。 - 过滤算子：
eq/gt/lt/gte/lte/in，多条取交集。 - 保留键：payload 不得使用
label键（400），label 走顶层字段。 - id 空间：u64；
houyidb.stable_id(str)可把字符串 id 确定性映射进 u64。 - v1 易失性：collection 的 payload/标量页不写 WAL，进程重启后丢失（向量索引不受影响）。
- 错误：非 2xx 一律抛
HouyiError(status_code, message)。
