We fixed the wasm-integration check earlier today, I think you can pull latest from the develop branch and should fix it |

There was a problem hiding this comment.
I think this is in the direction of the apis we need. We will also need to add writing arrow recordbatch stream

Summary
Closes: #7204
Currently writeBatch accepts Arrow IPC serialized bytes (byte[]), which requires serialization/deserialization overhead. We wants a writeBatchFfi path that directly accepts raw Arrow C Data Interface pointers (arrow_array_addr and arrow_schema_addr), avoiding the IPC round-trip.
We have conducted some internal tests, and the cost of serialization may reach 20% of the cost of writing.
