ploadText

ploadText(filename, [delimiter], [schema], [skipRows=0], [arrayDelimiter], [containHeader])

Please refer to function loadText.

Load a text data file in parallel as an in-memory partitioned table. It returns a in-memory table with sequential partitions. ploadText is faster than loadText.

Note: From version 2.00.10 onwards, function ploadText supports loading a data file that contains a record with multiple newlines.

n=1000000
timestamp=09:30:00+rand(18000,n)
ID=rand(100,n)
qty=100*(1+rand(100,n))
price=5.0+rand(100.0,n)
t1 = table(timestamp,ID,qty,price)
saveText(t1, "C:/DolphinDB/Data/t1.txt");

timer tt1=loadText("C:/DolphinDB/Data/t1.txt");
// output
Time elapsed: 437.236 ms

timer tt2=ploadText("C:/DolphinDB/Data/t1.txt");
Time elapsed: 241.126 ms

typestr(tt2);
