Abstract
Cracking page-loadable columns for in-memory data management is described herein. An embodiment operates by accessing a column according to a received query, determining that the received query requires a non-critical data structure associated with the column, and rebuilding the non-critical data structure from data associated with the column.
Claims20
A method, comprising:
- accessing, by at least one processor, a column according to a received query;
- determining, by at least one processor, that the received query requires a non-critical data structure associated with the column;
- and
- rebuilding, by at least one processor, the non-critical data structure from data associated with the column.
A system, comprising:
- a memory;
- and
- at least one processor communicatively coupled to the memory and configured to:
- access a page-loadable column according to a received query;
- determine that the received query requires a non-critical data structure associated with the page-loadable column;
- and
- rebuild the non-critical data structure from data associated with the page-loadable column.
A tangible, non-transitory computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:
- accessing a column according to a received query;
- determining that the received query requires a non-critical data structureassociated with the column;
- and
- rebuilding the non-critical data structure from data associated with the column.
