`NumericBuilder` uses the `pool` (`MemoryPool*`) parameter to initialise the `ArrayBuilder` base class, but does not use it to initialise its own internal builder, `data_builder_` (`TypedBufferBuilder`). For comparison `ArrayBuilder` uses the `pool` to initialise its own `null_bitmap_builder_` member (also a `TypedBufferBuilder`). This effect was observed when trying to switch to a custom `MemoryPool` for performance reasons. A hook was used to detect any use of the `MemoryPool` proved by `default_memory_pool()`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
