lake.intraday_stock dataset schema

Columns and types

These columns come from the same versioned logical catalog used by the query validator and engine. They describe the fields you can query. Some historical rows have missing values; fields absent from older shards can return typed NULL.

Current logical schema for lake.intraday_stock

Coverage and timing

Minute-level equity bars. Requires an explicit ticker list and a literal `timestamp` range. One object per day, so the range decides what is read and an unbounded query is rejected: e.g. `timestamp >= TIMESTAMP '2026-09-01' AND timestamp < TIMESTAMP '2026-09-19'`. For coverage questions (first/last date on file), bound a window or use lake.sec_daily_ohlc (lake.index_prices for an index).

Minute bars for equities; `ticker` is the bare symbol (`AAPL`, `SPY`). Always give an explicit `ticker IN (...)` and a bounded `timestamp` range — an unbounded scan reads every shard.

Run a limited query

Use a registered API key with lake scope. Select needed columns, bind user-supplied values and restrict dates when the table has a time dimension. Query results are durable parts with a schema and manifest rather than an unbounded in-memory array.

This reference documents the schema and its meaning. Run queries in your signed-in workspace; this page does not execute SQL or show private results and datasets.
