What is a more efficient way to insert multiple partitions with spring-data-cassandra?
Hello,
The bottleneck of inserting these 600 rows maybe not Spring Data Cassandra, but spring boot.
If your Cassandra code is used from the spring boot and invoked via HTTP, you may want to consider increasing the number of threads in spring (thread pool)
Regarding Spring-Data-Cassandra and possible performance improvements:
1. If you are using CqlTemplate, consider reworking your logic to async version: AsyncCqlTemplate, or reactive: ReactiveCqlTemplate
2. Leverage PrerparedStatement (instead of SimpleStatement) and use it in subsequent queries to reduce overhead when sending each query
3. Use BatchStatement to batch N statements that will be sent as a one batch request.
