I have a Google BigQuery clustered partition table. And I am trying to get Google BigQuery clustered partition table definition using bq.py cli tool. I get the json output but it does not have clustering information.
% bq version
This is BigQuery CLI 2.0.69
% bq show \
--schema \
--format=prettyjson \
uk-kingdom-911:ld_cv_1_population.cv_performance_t1_agg3_auh_mvpart
[
{
"name": "hstamp",
"type": "TIMESTAMP"
},
{
"name": "account_id",
"type": "INTEGER"
},
....
.....
]
Json output does not have clustering information. Not sure what I am missing here.
That's because you've used the --schema
flag. The --schema
flag only shows the basic schema of the table and nothing else. Remove that flag and you should see everything:
> bq show --format=prettyjson example_ds.test_table
