We encountered an error while trying to stream data into bigquery table, it says: payload size limit of 10485760 bytes, anyone has any idea of it? According to the third party integration vendor which we use to move data across from sql server to bigquery table, they advised it is an issue by bigquery?
Thanks.
Best regards,
BigQuery has some maximum limitations and also has some quotas policies as you can see here.
The limitations for Streaming are:
If you do not populate the insertId field when you insert rows:
Maximum rows per second: 1,000,000
Maximum bytes per second: 1 GB
If you populate the insertId field when you insert rows:
Maximum rows per second: 100,000
Maximum bytes per second: 100 MB
The following additional streaming quotas apply whether or not you populate the insertId field:
Maximum row size: 1 MB
HTTP request size limit: 10 MB
Maximum rows per request: 10,000 rows per request
insertId field length: 128
I hope it helps
Indeed the streaming limit is 10MB per request.
Row size is 1MB according to https://cloud.google.com/bigquery/quotas
What you need to do is parallelize the streaming jobs. BigQuery supports up to 1M/rows per second.

I am using a free trial of Google bigquery. This is the query that I am using.
select * from `test`.events where subject_id = 124 and id = 256064 and time >= '2166-01-15T14:00:00' and time <='2166-01-15T14:15:00' and id_1 in (3655,223762,223761,678,211,220045,8368,8441,225310,8555,8440)
This query is expected to return at most 300 records and not more than that.
However I see a message like this as below
But the table on which this query operates is really huge. Does this indicate the table size? However, I ran this query multiple times a day
Due to this, it resulted in error below
Quota exceeded: Your project exceeded quota for free query bytes scanned. For more information, see https://cloud.google.com/bigquery/troubleshooting-errors
How long do I have to wait for this error to go-away? Is the daily limit 1TB? If yes, then I didn't not use close to 400 GB.
How to view my daily usage?
If I can edit quota, can you let me know which option should I be editing?
Can you help me with the above questions?
According to the official documentation
"BigQuery charges for queries by using one metric: the number of bytes processed (also referred to as bytes read)", regardless of how large the output size is. What this means is that if you do a count(*) on a 1TB table, you will supposedly be charged $5, even though the final output is very minimal.
Note that due to storage optimizations that BigQuery is doing internally, the bytes processed might not equal to the actual raw table size when you created it.
For the error you're seeing, browse the Google Console to "IAM & admin" then "Quotas", where you can then search for quotas specific to the BigQuery service.
Hope this helps!

To BigQuery experts,
I am working on the process which requires us to represent customers shopping history in way where we concatenate all last 12 months of transactions in a single column for Solr faceting using prefixes.
while trying to load this data in BIG Query, we are getting below row limit exceed error. Is there any way to get around this? the actual tuple size is around 64 mb where as the avro limit is 16mb.
[ ~]$ bq load --source_format=AVRO --allow_quoted_newlines --max_bad_records=10 "syw-dw-prod":"MAP_ETL_STG.mde_golden_tbl" "gs://data/final/tbl1/tbl/part-m-00005.avro"
Waiting on bqjob_r7e84784c187b9a6f_0000015ee7349c47_1 ... (5s) Current status: DONE
BigQuery error in load operation: Error processing job 'syw-dw-prod:bqjob_r7e84784c187b9a6f_0000015ee7349c47_1': Avro parsing error in position 893786302. Size of data
block 27406834 is larger than the maximum allowed value 16777216.
Update: This is no longer true, the limit has been lifted.
BigQuery's limit on loaded Avro file's block size is 16MB (https://cloud.google.com/bigquery/quotas#import). Unless each row is actually greater than 16MB, you should be able to split up the rows into more blocks to stay within the 16MB block limit. Using a compression codec may reduce the block size.
I'm getting 403 rateLimitExceeded errors while doing streaming inserts into BigQuery. I'm doing many streaming inserts in parallel, so while I understand that this might be cause for some rate limiting, I'm not sure what rate limit in particular is the issue.
Here's what I get:
{
"code" : 403,
"errors" : [ {
"domain" : "global",
"message" : "Exceeded rate limits: Your table exceeded quota for rows. For more information, see https://cloud.google.com/bigquery/troubleshooting-errors",
"reason" : "rateLimitExceeded"
} ],
"message" : "Exceeded rate limits: Your table exceeded quota for rows. For more information, see https://cloud.google.com/bigquery/troubleshooting-errors"
}
Based on BigQuery's troubleshooting docs, 403 rateLimitExceeded is caused by either concurrent rate limiting or API request limits, but the docs make it sound like neither of those apply to streaming operations.
However, the message in the error mentions table exceeded quota for rows, which sounds more like the 403 quotaExceeded error. The streaming quotas are:
Maximum row size: 1 MB - I'm under this - my average row size is in the KB and I specifically limit sizes to ensure they don't hit 1MB
HTTP request size limit: 10 MB - I'm under this - my average batch size is < 400KB and max is < 1MB
Maximum rows per second: 100,000 rows per second, per table. Exceeding this amount will cause quota_exceeded errors. - can't imagine I'd be over this - each batch is about 500 rows, and each batch takes about 500 milliseconds. I'm running in parallel but inserting across about 2,000 tables, so while it's possible (though unlikely) that I'm doing 100k rows/second, there's no way that's per table (more like 1,000 rows/sec per table max)
Maximum rows per request: 500 - I'm right at 500
Maximum bytes per second: 100 MB per second, per table. Exceeding this amount will cause quota_exceeded errors. - Again, my insert rates are not anywhere near this volume by table.
Any thoughts/suggestions as to what this rate limiting is would be appreciated!
I suspect you are occasionally submitting more than 100,000 rows per second to a single table. Might your parallel insert processes occasionally all line up on the same table?
The reason this is reported as a rate limit error is to give a push-back signal to slow down: to handle sporadic spikes of operations on a single table, you can back off and try again to spread the load out.
This is different from a quota failure which implies that retrying will still fail until the quota epoch rolls over (for ex, daily quota limits).
When trying to load data into a big query table, I get an error telling me a row is larger than the maximum allowed size. I could not find this limitation anywhere in the documentation. What is the limit? And is there a workaround?
The file is compressed json and is 360M.
2018 update: 100 MB maximum row size. https://cloud.google.com/bigquery/quotas
The maximum row size is 64k. See: https://developers.google.com/bigquery/docs/import#import
The limitation for json will likely increase soon.
2013 update: The maximum row size is 1MB, and 20MB for JSON.
See: https://developers.google.com/bigquery/preparing-data-for-bigquery#dataformats
2017 update: 10MB for CSV & JSON. https://cloud.google.com/bigquery/quotas#import
Except 1MB if streaming, https://cloud.google.com/bigquery/quotas#streaminginserts
Is there a limit to the amount of data that can be put in a single row in BigQuery? Is there a limit on the size of a single column entry (cell)? (in bytes)
Is there a limitation when importing from Cloud Storage?
The largest size of a single row allowed is 1MB for CSV and 2 MB for JSON. There are no limits on field sizes, but obviously they must be under the row size as well.
These limits are described here.
