Correct Answer:
Explanation:
Box 1: No
Azure Cosmos DB's change feed is a great choice as a central data store in event sourcing architectures where all data ingestion is modeled as writes (no updates or deletes). Note: The change feed does not capture deletes. If you delete an item from your container, it is also removed from the change feed. The most common method of handling this is adding a soft marker on the items that are being deleted. You can add a property called "deleted" and set it to
"true" at the time of deletion. This document update will show up in the change feed. You can set a TTL on this item so that it can be automatically deleted later.
Box 2: No
The _etag format is internal and you should not take dependency on it, because it can change anytime.
Box 3: Yes
Change feed support in Azure Cosmos DB works by listening to an Azure Cosmos container for any changes.

注：正解ごとに1ポイントが加算されます。
Correct Answer:
Explanation:
Box 1: Range
Range index is based on an ordered tree-like structure. The range index type is used for:
Equality queries:
SELECT * FROM container c WHERE c.property = 'value'
SELECT * FROM c WHERE c.property IN ("value1", "value2", "value3")
Box 2: Composite
Composite indexes increase the efficiency when you are performing operations on multiple fields.
The composite index type is used for:
Queries with a filter on two or more properties where at least one property is an equality filter SELECT * FROM container c WHERE c.property1 = 'value' AND c.property2 > 'value' Box 3: Composite Incorrect:
Spatial indices enable efficient queries on geospatial objects such as - points, lines, polygons, and multipolygon. These queries use ST_DISTANCE, ST_WITHIN, ST_INTERSECTS keywords.
