 Description   

Some notable improvements to be made, along with a general increased scrutiny for performance sensibility:

  • updates are doing a remove + insert rather than an update.
  • Use the WriteCursor API and reuse a WriteCursor rather than using the individual CRUD APIs which create individual temporary write cursors.
  • When inserting multiple object ("bulk insert") pass the column store cells grouped by column rather than by recordid.
