> flinksql client will hang when execute a query:
> {code:java}
> select * from table_foo where dt = "2024-10-21" {code}
> table_foo is a partitioned table. "2024-10-21" partition points to a dir on
> s3 containing 6000 parquet files.
> jstack shows the parquet-get-table-statistic-worker-threads are the running
> threads.
> the issue can be mitigated after:
> {code:java}
> table.optimizer.source.report-statistics-enabled: false
> source.report-statistics: NONE {code}
> However not sure about downside disabling this
