Terms in this definition
- Partitioning
Splits a table into directories, one per value of the column or columns named in
PARTITIONED BY. Learn favours liquid clustering in most cases and keeps this technique for very large tables. - BIOS
Generation 2 Hyper-V machines use UEFI with Secure Boot; Generation 1 machines rely on this older firmware.
- UEFI
The modern firmware standard that took over from BIOS. Because Hyper-V generation 2 machines use it, they can start up from a virtual SCSI disk and have Secure Boot switched on.
- GPT
A family of large language models from OpenAI, based on the transformer architecture and pretrained on big text collections, used to understand and produce language and code.
