Budgeting Your Cache Carefully
Carefully budget your cache to avoid excessive memory consumption. Over-allocating cache can lead to HEAP memory pressure, causing frequent garbage collection and degraded performance. Regularly review cache usage metrics and adjust cache sizes to ensure a balance between memory usage and query performance.
Elasticsearch Performance Tuning
As your Elasticsearch cluster grows and your usage evolves, you might notice a decline in performance. This can stem from various factors, including changes in data volume, query complexity, and how the cluster is utilized. To maintain optimal performance, it’s crucial to set up monitoring and alerting systems that can preemptively highlight issues, allowing you to manage maintenance effectively.
