Search Restrictions Solution: ALLOW FILTERING option
Explore the search restrictions imposed by primary keys in Apache Cassandra and learn how to use the ALLOW FILTERING option to overcome these query limitations. Understand the associated performance trade-offs and gain hands-on experience executing queries that include non-primary key columns while managing the impact on cluster performance.
We'll cover the following...
In Apache Cassandra, the table’s primary key imposes restrictions on search conditions, impacting the design of the relational model. In this lesson, we will focus on these limitations and their solutions.
To reiterate, in a SELECT query:
Only the columns that are part of the primary key can be used in the
WHEREclause as filtering conditions.Only equality searches can be performed on partition key columns. Range queries are allowed on clustering columns.
If the partition ...
