A method can include receiving a request to execute a database command identifying a target table; identifying a plurality of rows to insert into the target table based in part on the database command; writing rows, from the plurality of rows, into a data page until the data page is full; determining, by an index thread manager, a number of threads to use for updating indexes defined for the target table; and upon determining the data page is full, updating, in parallel, the indexes defined for the target table using the number of threads.

Index updates using parallel and hybrid execution

A method can include initiating execution of a database command, the database command associated with a base table with at least one row to copy to a target table, the database command associated with a non-bulk insert mode; making a run-time decision on whether to automatically convert the insert mode from the non-bulk insert mode to a BULK insert mode based on the number of row buffers filled with rows from the base table during execution of the database command; and inserting at least one row into the target table using an insert mode based on the run-time decision.

Run-time decision of bulk insert for massive data loading

A method for inserting rows into a target table can include receiving a database command, the database command associated with a base table with at least one row to copy to a target table; receiving an indication that use of a BULK insert mode is feasible for the database command; based on the indication, and determining that an insert mode for the database command has been converted from a non-bulk insert mode to the BULK insert mode: reading a row from the base table; building the row read from the base table into an allocated row buffer; inserting the row into the target table in the BULK insert mode; and if it is determined that the allocated row buffer is full, updating at least one index in parallel with the inserting.
