Make lineitem SF 10 (3 seconds!) data using tpchgen-cli https://github.com/clflushopt/tpchgen-rs ```shell tpchgen-cli -v --tables=lineitem --scale-factor=10 --format=parquet ``` Then you can run split to strings ```sql > select unnest (string_to_array(l_comment, ' ')) as word from 'lineitem.parquet' limit 10; +---------------+ | word | +---------------+ | egular | | courts | | above | | the | | ly | | final | | dependencies: | | slyly | | bold | | | +---------------+ 10 row(s) fetched. Elapsed 0.024 seconds. ``` Do the count ```sql > select count(*) from (select unnest (string_to_array(l_comment, ' ')) as word from 'lineitem.parquet'); +-----------+ | count(*) | +-----------+ | 271168008 | +-----------+ 1 row(s) fetched. Elapsed 0.731 seconds. ``` You can even do the distinct word count: ```sql > select count(distinct word) from (select unnest (string_to_array(l_comment, ' ')) as word from 'lineitem.parquet'); +----------------------+ | count(DISTINCT word) | +----------------------+ | 4959 | +----------------------+ 1 row(s) fetched.
