From 852f1d2f0597ba7d182ecd6c375f1ba81f56f0fd Mon Sep 17 00:00:00 2001 From: Nicholas Gates Date: Wed, 22 Jan 2025 11:42:56 +0000 Subject: [PATCH] Array Metadata (#1985) The current ArrayMetadata system was put together somewhat quickly and uses `serde` + Flexbuffers to serialize all metadata. The end state looks like this: - [ ] An array has a fixed 8 bytes of metadata. If it needs more, it should use a buffer (made possible by #1743) - [ ] Rkyv can optionally be used to help with serde for these bytes. - [ ] No eager deserialization of metadata is performed, although arrays should validate metadata in the `ValidateVTable` (see #1979). To support 8 byte metadata, we need to: - [ ] Move scalars and scalar values out of metadata (e.g. ConstantArray) - [ ] Move shift from FoR into BitPacking (this is a bit cheeky, it's not strictly necessary, but FoR is then left with a 8-byte PValue for metadata, and shifting feels like it should live in BitPacking anyway?) - [ ] All other metadata should easily fit into 8 bytes. --- Cargo.lock
