We need to add the term_full_entity_id column to wb_terms table on test wikidata (testwikidatawiki, which is on s3)
select count(*) from wb_terms; +----------+ | count(*) | +----------+ | 192947 | +----------+
In this case, not sure we can directly apply this change using sql.php script (https://wikitech.wikimedia.org/wiki/How_to_do_a_schema_change#sql.php) which we use for smaller changes or adding tables where replication lag won't be a concern.
maybe can use OSC for this? or whatever the dbas think is best.
