Jadw1	c921efd1b3	cql3: allow no final_func and no initcond in UDA ... Makes final function and initial condition to be optional while creating UDA. No final function means UDA returns final state and defeult initial condition is `null`. Fixes: #10324	2022-04-06 09:08:50 +02:00
Avi Kivity	fcb8d040e8	treewide: use Software Package Data Exchange (SPDX) license identifiers ... Instead of lengthy blurbs, switch to single-line, machine-readable standardized (https://spdx.dev) license identifiers. The Linux kernel switched long ago, so there is strong precedent. Three cases are handled: AGPL-only, Apache-only, and dual licensed. For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0), reasoning that our changes are extensive enough to apply our license. The changes we applied mechanically with a script, except to licenses/README.md. Closes #9937	2022-01-18 12:15:18 +01:00
Piotr Sarna	ee81453596	cql3: add user-define aggregate representation ... A user-defined aggregate is represented as an aggregate which calls its state function on each input row and then finalizes its execution by calling its final function on the final state, after all rows were already processed.	2021-08-13 11:13:41 +02:00
