Analytics Secondary Index Entry Size Limitation

We need to document the maximum Analytics secondary index entry size limitation. Here are the details:

Limitation: Analytics secondary index maximum entry size
Maximum Value: 65523 bytes
Description: The maximum allowed entry size (including the size of all fields in the secondary index and the primary key) of an Analytics secondary index is 65523 bytes. Secondary index creation will fail if an index entry larger than the allowed size is encountered during index creation. If a secondary index already exists, ingested documents that result in exceeding the maximum allowed index entry size will cause ingestion failures.

We probably should add it to this page as a note:

and possibly this page if you see that it fits:
