Change subject: [tools] perf loadgen: support configurable column counts for auto-created table ...................................................................... [tools] perf loadgen: support configurable column counts for auto-created table `kudu perf loadgen` always creates a fixed 3-column table (`key INT64 PK`, `int_val INT32`, `string_val STRING`) when --table_name is not provided. Benchmarking wide-row workloads currently requires pre-creating a table out-of-band and pointing loadgen at it via --table_name, which is inconvenient for parameter sweeps over column count. This patch adds two flags: --table_num_int_columns (default 1) --table_num_string_columns (default 1) When both default to 1 the auto-created schema is byte-for-byte identical to before (column names `int_val`, `string_val` are preserved). Setting either to N >= 2 produces N suffix-numbered columns of that type; 0 omits that column type entirely. This patch is intentionally limited to INT32 / STRING column counts. DECIMAL precision, VARCHAR length, and encoding are out of scope; users needing those should pre-create a table and pass --table_name. They are noted as possible follow-ups.
