SQL for bulk insert

support syntax for insert of multiple rows at once:

INSERT INTO table_name (column_list)
VALUES
    (value_list_1),
    (value_list_2),
    ...
    (value_list_n);

Unknowns

Investigate if PostgreSQL supports bind variables in statement like that.

Implementation

It is very likely this insert will need to be executed without creating intermediate model. The existing QuestDb’s implementation of Insert is also deficient and this is an opportunity to prove it.

Considerations

• insert should convert constant types similarly to how BindVariableService does. In that it should be possible to insert null into primitive types, such as int, long etc. It should also be possible to insert constant int into short and byte column, numeric value into char column etc.

• The implementation should be efficient and performant for frequent execution of insert statements

• The implementation must not generate grabage

hi @Shivansh-Mittal you parse the JSON file in C# and then use a Postgres client to connect to QuestDB and use SQL bulk update as documented here

Can I insert json file data in my questdb table from C# ?
