Describe the bug
Using a time dimension on a runningTotal measure on Snowflake mixes quoted and unquoted columns in the query. This fails the query, because Snowflake has specific rules about quoted columns. Specifically:

• All unquoted column names are treated as upper case
• Quoted column names are case sensitive.

So "date_from" <> date_from

It would be great to do a somewhat rigorous analysis of whether there are performance issues when query is written in Logica vs SQL.

As a user i would like a command to aid in debugging parquet files. For instance I would like to obtain the following file stats in a single command:

• compression algorithm
• page type v1/v2?
• row group size
• author / created by
• version
• metadata
• page size
• total records /row count
• any internal info that could help too

The flink-tidb-connector doesn't work as expected when I use upsert mode to sink data to TiDB, the reason for this is as in title, flink version: 1.13.x. Is there any reason for making unique key as part of the primary?

Code block:

private String[] getKeyFields(Context context, ReadableConfig config, String databaseName,
      String tableName) {
    // check write mode
    TiDBWr
