GRAIN & TIME
一行代表什么
- 业务粒度
- 每行代表“加密货币清算热力图”的一条记录；逻辑粒度由 symbol × bucket_ts × price_level × snapshot_date × venue 共同确定。
- 时间口径
- 以 snapshot_date 为主要查询时间轴；除下方限制特别说明外，时间戳按 UTC、日期按来源市场日历解释。
- 更新节奏
- 交易时段内可多次更新；请检查时间列判断新鲜度。
KEY FIELDS
先看这些字段
symbol- 证券或交易对的展示代码。
bucket_ts- 聚合时间桶的起始或代表时点。
price_level- 用于确定该表业务粒度或默认顺序的 price level 字段。
snapshot_date- snapshot date 对应的日历日期。
venue- 用于确定该表业务粒度或默认顺序的 venue 字段。
RECOMMENDED JOINS
怎样和其他表关联
该表主要按自身业务键使用，目前没有推荐的跨表主键联接。
HOW TO QUERY SAFELY
查询方法与已知限制
先用 catalog 确认当前契约；可按 catalog 中列出的 filters 进一步缩小范围；单页最多 5000 行，该表不提供稳定 cursor，结果过大时必须缩小标的、日期或其他筛选。
- 返回范围仍受 Friends 权限、单页上限和 catalog 中的筛选契约约束。
MACHINE CONTRACT
筛选、排序与分页
- 默认排序
snapshot_date, symbol, venue, bucket_ts- 唯一键
—- 读取模式
canonical_final_active- 最大时间窗
- 未单独限制
可用 filters
market_kind→ market_kind · stringmodel→ model · stringsource→ source · stringsymbol→ symbol · stringvenue→ venue · stringPOINT IN TIME
可复现读取
该资产没有 PIT 契约。普通 rows 端点仍按当前公开读模式返回数据；不要把它表述成历史时点快照。
