Adds Altertable, a DuckDB-based managed lakehouse, with results from 2026-10-27.

Six compute sizes, one node each, default settings (tuned: no): M, L, XL, 2XL, 3XL, and 4XL.

How it was run

• benchmark.sh downloads hits_compatible/hits.parquet, rewrites it locally with DuckDB so EventTime, ClientEventTime, and LocalEventTime are real timestamps and EventDate is a date (the published Parquet stores those as raw integers), then uploads that file once into catalog clickbench, schema main, table hits.
• Load time is that upload: 149 seconds. It is the same on every size because the table is loaded once and each size only changes the compute used for queries.
• queries.sql is the standard 43 queries in DuckDB SQL (STRLEN, REGEXP_REPLACE, extract(minute FROM …), DATE_TRUNC).
• run.sh posts each query to the HTTP API and records the server-reported duration_ms. That is execution time on the service. It does not include transferring the result back to the client.

Reproduction needs ALTERTABLE_USERNAME and ALTERTABLE_PASSWORD. ALTERTABLE_COMPUTE_SIZE selects the size (L by default).
