https://github.com/developmentseed/lonboard serializes all array or table data via Arrow and Parquet. The Python side [defines traits to validate and store](https://github.com/developmentseed/lonboard/blob/8e97480d79790df1b35f14b758fe1635f0450b8b/lonboard/traits.py#L113) `Table`, `Array`, and `ChunkedArray` objects. Each of those has [custom serializers](https://github.com/developmentseed/lonboard/blob/8e97480d79790df1b35f14b758fe1635f0450b8b/lonboard/traits.py#L142) which [serialize to Parquet](https://github.com/developmentseed/lonboard/blob/8e97480d79790df1b35f14b758fe1635f0450b8b/lonboard/_serialization.py#L70-L72) (for my uses, a list of Parquet files rather than one Parquet file with many chunks). Then in JS it [parses those Parquet buffers to an Arrow JS table](https://github.com/developmentseed/lonboard/blob/8e97480d79790df1b35f14b758fe1635f0450b8b/src/model/layer.ts#L48). -- This is an automated message from the Apache Git Service.
