[Bug]: write table by FFI call from go may memory leak?

[z2665]

What happened?

memory leak when call delta-rs to write table

Expected behavior

delta-rs uses finite memory instead of infinite growth

Operating System

Linux

Binding

Rust

Bindings Version

0.29.3

Steps to reproduce

1. The program receives a -target flag (local or s3) and prepares that table once (creating or cleaning as needed).
2. For each of the ten iterations it:
   • Opens the target table.
   • Appends 100 synthetic rows.
   • Closes the table and records RSS in megabytes.
3. Iterations execute every five seconds unless interrupted with Ctrl+C.
4. After the loop completes, the program writes a single plot named <target>_memory.png.

Run the experiment with:

cd  go_ffi_delta_rs
GOOS=linux GOARCH=amd64 go run . -target local
GOOS=linux GOARCH=amd64 go run . -target s3

write to local result

write to s3 result
