 - Joins (left/right/inner) are pushdowned
 - Limit and Offset are pushdowned (*when all tables queried are fdw)
 - Transactions  
+- Support TRUNCATE by deparsing into DELETE statement without WHERE clause  
+- Allow control over whether foreign servers keep connections open after transaction completion. This is controlled by `keep_connections` and defaults to on  
+- Support list cached connections to foreign servers by using function sqlite_fdw_get_connections()  
+- Support discard cached connections to foreign servers by using function sqlite_fdw_disconnect(), sqlite_fdw_disconnect_all().  
+- Support Bulk Insert by using batch_size option  
 
 ## Limitations
 - `COPY` command for foreign tables is not supported
 - Insert into a partitioned table which has foreign partitions is not supported
+- TRUNCATE in sqlite_fdw always delete data of both parent and child tables (no matter user inputs `TRUNCATE table CASCADE` or `TRUNCATE table RESTRICT`) if there are foreign-keys references with "ON DELETE CASCADE" clause.
