Eclipse OQL Memory Analysis

The tool enables deep heap analysis by running OQL queries on Eclipse Memory Analyzer dumps. It returns per-object metrics and can identify memory leaks by tracing retention paths. This supports developers in pinpointing the largest retainers and understanding object lifetimes. It works conceptually by treating the heap dump as a graph of objects and edges; OQL queries select nodes and edges, producing a tabular result with key fields for decision making. The unique value lies in combining MAT's mature OQL engine with structured outputs and export options, enabling repeatable analyses across builds. Typical use cases include validating fixes, comparing dumps from different versions, and prioritizing memory-optimization work based on retention impact. Core features include query support for filtering and sorting, path extraction to GC roots, and export to JSON/CSV for reporting. The tool is language- and platform-agnostic at the analysis layer but targets Java heap dumps generated by the JVM and MAT. By providing deterministic results on identical dumps, teams can track regressions and measure improvements in memory usage and leak mitigation.
