Hi,
At the bottom please find the session_info.
When creating north of 200-300 batches, the writing to the arrow file crashes R
– it doesn’t even show an error message. Rstudio just aborts.
I have the feeling that maybe each batch becomes a stream and R has issues with
the connections, but that’s a total guess.
Any help would be appreciated.
##
Here is the function. When running it with 3000 it crashes immediately.
Before that I ran it with 100, and then increased it slowly, and then it
randomly crashed again.
write_arrow_custom(data.frame(A=c(1:100000),B=c(1:100000)),'C:/Temp/test.arrow',3000)
write_arrow_custom <- function(df,targetarrow,nrbatches) {
ct <- nrbatches
idxs <- c(0:ct)/ct*nrow(df)
idxs <- round(idxs,0) %>% as.integer()
idxs[length(idxs)] <- nrow(df)
df_nav <- idxs %>% as.data.frame() %>% rename(colfrom=1) %>%
mutate(colto=lead(colfrom)) %>% mutate(colfrom=colfrom+1) %>%
filter(!is.na(colto)) %>% mutate(R=row_number())
stopifnot(df_nav %>% mutate(chk=colto-colfrom+1) %>% '$'('chk') %>%
sum()==nrow(df))
table_df <- Table$create(name=rownames(df[1,]),df[1,])
writer <- RecordBatchFileWriter$create(targetarrow,table_df$schema)
df_nav %>% dlply(c('R'),function(df_nav){
catl(glue('{df_nav$colfrom[1]}:{df_nav$colto[1]} / {df_nav$R[1]}...'))
tmp <- df[df_nav$colfrom[1]:df_nav$colto[1],]
writer$write_batch(record_batch(name = rownames(tmp), tmp))
NULL
}) -> batch_lst
writer$close()
rm(batch_lst)
gc()
}
