https://github.com/brimdata/zed/issues/1783#issuecomment-751790854 introduced the building blocks of `shape()`, specifically the four functions `cast()`, `crop()`, `fill()`, and `order()`. While these can be used "a la carte", @henridf correctly made the point in...
At the time of the filing of this issue, Zed is at commit 9abaa77. A community user asked the following in a [Slack thread](https://brimdata.slack.com/archives/CTT24051C/p1698753307402599): > I am working with some...
Repro is with Zed commit 63d6b29. This variation was actually first called out in https://github.com/brimdata/zed/issues/4651#issuecomment-1622343020. Here's an example of something that's easy in Python, which might be familiar to our...
Repro is with Zed commit e03665e. This issue was first reported by a community user in a [Slack thread](https://brimdata.slack.com/archives/CTSMAK6G7/p1698306082682539?thread_ts=1698066990.787509&cid=CTSMAK6G7). Start an empty lake in one terminal. ``` $ zed -version...
This issue builds on the vector's filter + projection capability with aggregations and group-bys. Here filtering and selection of fields will create vectors that are then fed into a native...
This issue builds on #4818 by adding filtering to the vector engine's projection capability. Here simple filtering of fields (with boolean logic) can be pushed into the vector scanner where...
The first step toward a working vector engine is simple projection. In this issue, we will wire the vector engine into the runtime so that it is actually invocable from...
The unfinished vcache implementation currently loads vectors into memory and never evicts them. In this issue, we will extend the vcache API with ownership (so a query can release vectors...
