Re: Regarding feature #3319

Hi Hackers,

We are going to store the below details

1. List of Query tools opened
2. List of connections present in each query tool
3. Each connection’s details that are required to make the connection
once the application restarts
4. Active connection details of each query tool opened
5. Store the query that is written in the editor that may or may not be
executed
6. Store the contents of the scratch pad
7. Store the file which is opened in the query tool with any unsaved
changes

Some questions that I have are mentioned below,

1. For desktop mode the application is opened with some query tools and
the user closes the application and on restarts the tabs will open as it is
and will restore the workspace and connections on query tool tabs. But for
server mode do we need to restore the query tool tabs and workspace?
Because we see most of the desktop applications have this feature.
2. I came across one issue reported by one user i.e
https://github.com/pgadmin-org/pgadmin4/issues/6666, where pgAdmin
crashed due to long SQL scripts that can be in Megabytes stored as query
history. We fixed it by giving MAX_QUERY_LENGTH to 1000000, and
checking if any query length is below the value then it gets stored in the
database as query history else not. Should we go with storing the workspace
and query tool details in SQLite DB or use a file system to store the
details and retrieve the content accordingly?

Please let me know your suggestions on this.

Thanks
Anil
