thanks @Moelf .
I tried this code, but removal still gives error
```julia
offline_run!(model, 365 * 5;
when_model = each_year,
when = six_months,
backend = :arrow,
mdata = [:flag, :year],
adata = [(:weight, mean)],
writing_interval = 3
)
adata_arrow = Arrow.Table("adata.arrow")
adata_saved = DataFrame(adata_arrow)
@test size(adata_saved) == (11, 2)
@test propertynames(adata_saved) == [:step, :mean_weight]
mdata_arrow = Arrow.Table("mdata.arrow")
mdata_saved = DataFrame(mdata_arrow)
@test size(mdata_saved) == (6, 3)
@test propertynames(mdata_saved) == [:step, :flag, :year]
adata_stream_arrow = Arrow.Stream("adata.arrow")
mdata_stream_arrow = Arrow.Stream("mdata.arrow")
@test size(vcat(DataFrame.(adata_stream_arrow)...)) == (11, 2)
@test size(vcat(DataFrame.(mdata_stream_arrow)...)) == (6, 3)
if Sys.iswindows()
mdata_arrow = nothing
mdata_saved = nothing
mdata_stream_arrow = nothing
adata_stream_arrow = nothing
for _ in 1:5
GC.gc()
end
end
```
