lightning v5.3.0

After the content in parquet may be written by spark, the definition of bool is true or false. Regenerating the parquet file takes time, In tidb, bool behaves as tinyint, so proper type conversion will help improve the success rate of lightning import

Sometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.

Unfortunately when one sees them in DBeaver he sees them compressed, but often they are needed uncompressed. So it'd be nice to have a feature to decompress the

The array overlap operator, &&, provides a convenient syntax for filtering for arrays that have one more more elements in common with another array. However, the && operator is not index accelerated, so an efficient inverted index scan in not planned. The current workaround is to rewrite the query by combining the containment operator with OR expressions:

CREATE TABLE movies (
  

We already have some scripts in the scripts directory. It would be good to run them for every PR.
This is also a great task for beginners.

Currently we only support Upsert for CockroachDB. Implementing same for MySQL should be pretty straightforward as well.

Wonder if we can also use INSERT ON CONFLICT UPDATE for PostgreSQL to ensure operation with same signature also works.

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

When I try to connect dolt server using golang's go-sql-driver/mysql driver in multiple heads mode, It seems that go-sql-driver/mysql driver does't support database with a sub name. DSN string format in go-sql-driver/mysql like [username[:password]@][protocol[(address)]]/dbname[?param1=value1&...&paramN=valueN]. When dbname is "mydb", It works, but not work when dbname is "mydb/feature-branch".

Hi,

my admin portal looks like this :

Version

• Server Installed 1.38.4
• Server Latest 1.38.4
• Web Installed -
• Web Latest 2.17.1

It seems that, at some point, 'GetInstalledWebVersion()' in 'Admin.dll' is called? Could anyone help me understand what do I need to check, to fix this?

Hi all. Congrats for the amazing software :)
