how do I split a large csv.gz file in Google Cloud Storage? -


i error when trying load table in google bq:

input csv files not splittable , @ least 1 of files larger maximum allowed size. size is: 56659381010. max allowed size is: 4294967296.

is there way split file using gsutil or without having upload again?

the largest compressed csv file can load bigquery 4 gigabytes. gcs unfortunately not provide way decompress compressed file, nor provide way split compressed file. gzip'd files can't arbitrarily split , reassembled in way tar file.

i imagine best bet spin gce instance in same region gcs bucket, download object instance (which should pretty fast, given it's few dozen gigabytes), decompress object (which slower), break csv file bunch of smaller ones (the linux split command useful this), , upload objects gcs.

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
