Example test for Frozen Bitmap fault when using Frozen Bitmaps as regular/mutable bitmaps with a read-only buffer

4

This is a test that should not pass but does, as it asserts a panic exactly when FrozenBitmaps and MMap is used. @a392n328 helped me diagnose these issues.

Fault When Creating Frozen Bitmap From MMapped

We have been trying to use Frozen Bitmaps for our internal system and were met with unanticipated faults. After working with @a392n328 we were able to write up this minimal...

Clarify In-Place operation semantics

Been fooling around with optimizing in-place operations, in particular if we can do better with run containers. My interest is in solutions that are performant both in terms of calculations...

Implement in-place xOrProduceAnd()

The pseudocode for addDigit in https://github.com/RoaringBitmap/roaring/issues/260 includes the two lines ``` carry := roaring.And(bsi.bA[i], bitmap) bsi.bA[i].Xor(bitmap) ``` `And()` and `Xor()` do basically the same operations. In both they iterate forward...

The i3 and *5d classes have published iOPs data, but it is pretty frustrating to find, as it isn't in the standard EC2 tables. You can find at pages like...

### Describe the bug If you attempt to join two tables on a struct field, the query will plan it successfully, albeit with the struct equality in a the `filter`,...

This reworks how our operators shutdown, both because of EndOfData messages and stopping checkpoints. It affects SourceOperators, ArrowOperators, and the controller. ### SourceOperator changes Two main changes here. First, rather...

Expand support for sql window functions to allow more functions, window definitions, and updating inputs

1

Arroyo supports window functions, but only under very specific circumstances: * Only ROW_NUMBER() is supported. * The input data can't be updating. * The first term of the partition clause...

#439 raised the issue of subtraction producing incorrect generated code, leading to a compile time failure. This is partially addressed in #441, which will return a planning error if a...

Both arroyo-controller and arroyo-compiler-service need to connect to the configured storage backend in order to run correctly. However, right now they don't attempt a connection until a user tries to...
