Module mz_persist_types::arrow
source · Expand description
A protobuf representation of Apache Arrow arrays.
§Motivation
Persist can store a small amount of data inline at the consensus layer. Because we are space constrained, we take particular care to store only the data that is necessary. Other Arrow serialization formats, e.g. Parquet or Arrow IPC, include data that we don’t need and would be wasteful to store.
Modules§
- proto 🔒
Structs§
- A struct representing a particular entry in a particular array. Most useful for its
Ord
implementation, which can compare entire rows across similarly-typed arrays.
Enums§
- Wraps a single arrow array, downcasted to a specific type.
