Is there an upper limit for the length of row keys?

Question

I want to know whether there's a maximum length for the row key values in Google's BigTable.

I'm aware the documentation recommends hashing as a potential solution to create keys of the same length, but in my scenario I can group related data better if I include a file path in my key.

Answer 1

In Cloud Bigtable:

The maximum length for row keys is 4KiB.

The maximum length for column qualifiers is 16 KiB.

This info is on the quotas and limits page in the documentation.
