Update: Exclude fields in Change Streams

[KenFujimoto12]

内容

Change Streams内のfulldocumentフィールドで、除外を可能にしたいという要望がありましたので、実装しました。
ローカルにて挙動確認済み。

e.g.
環境変数

MONGO_WATCH_PIPELINE_EXCLUDE_CS_FIELD=fullDocument.nest.nest1,fullDocument.firstName

投入データ

db.test.insert({"firstName":"ken","lastName":"fujimoto","gender":"male","age":"27","address":"tokyo","number":["0","1","2","3","4","5","6","7","8","9","10"],"nest":{"nest1":{"aaa":"AAA"},"nest2":{"bbb":"BBB"}}})

結果

{"logType":"changeStream","cs":{"_id":{"_data":"xxx"},"operationType":"insert","clusterTime":"2022-05-12T11:31:13+09:00","ns":{"coll":"test","db":"test"},"fullDocument":{"_id":"xxx","address":"tokyo","age":"27","gender":"male","lastName":"fujimoto","nest":{"nest2":{"bbb":"BBB"}},"number":["0","1","2","3","4","5","6","7","8","9","10"]},"documentKey":{"_id":"xxx"},"updateDescription":null}}

対象issues

こちら、fulldocument -> fullDocument のtypoかもしれません

あと、実際に実装ないで参照している環境変数は MONGO_WATCH_PIPELINE_EXCLUDE_CS_FULLDOCUMENT_FIELD のようです
