Anson Qian updated ARROW-4736:
------------------------------
Component/s: Go
> [Go] Optimize memory usage for CSV writer
> -----------------------------------------
>
> Key: ARROW-4736
> URL: https://issues.apache.org/jira/browse/ARROW-4736
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Go
> Reporter: Anson Qian
> Priority: Major
>
> perhaps not for this PR, but, depending on the number of rows and cols this
> record contains, this may be a very large allocation, and very big memory
> chunk.
> it could be more interesting performance wise to write n rows instead of
> everything in one big chunk.
> also, to reduce the memory pressure on the GC, we should probably (re)use
> this slice-of-slice of strings.
