In Azure Cosmos DB, the “Consistency Level” impacts data availability as follows:
Strong: Highest consistency, but can reduce availability during partitions.
Bounded Staleness: Balances consistency and availability with some allowed lag.
Session: Provides strong consistency for individual sessions, maintaining good availability.
Consistent Prefix: Ensures order of writes but allows for higher availability.
Eventual: Highest availability and performance, but data may be stale.
