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.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
