Development Roadmap

For PostgreSQL Core

• Pass-down Limit clause on ForeignScan/CustomScan (returned with feedback; v10)
• Callbacks to reclaim statistics of background-worker on DSM (v10 accepted)
• Long varlena support (works in progress)
• Matrix data type support
• Callbacks when all_visible is set/clear

v3.0 - (target: ????)

• Based on PostgreSQL v10
  • In-memory columnar cache
• GpuPreAgg + GpuJoin + GpuScan by mono-kernel
• PCI-E topology consideration on SSD-to-GPU P2P DMA
• Long varlena based Matrix support (PL/CUDA)
• Fully utilization of unified device memory on Pascal model.
  • Minimum requirement shall be pulled up to CC6.0 or later.
