BigQuery API limit exceeded error

Question

We\'ve got error during tabledata.list with message:

API limit exceeded: Unable to return a row that exceeds the API limits. To retrieve the row, export the          


        

Answer 1

There are two row related limits for tabledata.list:

1. The byte size of the proto message has to be less than 10M. If one row is larger than this size, we cannot retrieve it.

2. The max field value in the row has to be less than 350,000, that is the number of leaf fields of a row.

If you hit that problem, it usually only means the first row in your request is too large to return, if you skip that row, the following row retrieval might work. You may try look at the particular row closer to see why.

In the future, it is likely the field value limit can be removed, but we will still have the 10M size limit due to API server limitations.
