Option 4 Architecture:

Key Differences from SCM:

+ *
    + *
  1. Uses NullContainerReplicaPendingOps stub (no pending operations tracking)
    2. + *
  2. Overrides processAll() to capture ALL container health states (no 100-sample limit)
    3. + *
  3. Stores results in Recon's UNHEALTHY_CONTAINERS_V2 table
    4. + *
  4. Does not issue replication commands (read-only monitoring)
    5. + *
+ * + *

Why This Works Without PendingOps:

+ *

SCM's health check logic uses a two-phase approach: + *

    + *
  • Phase 1 (Health Determination): Calls isSufficientlyReplicated(false) + * which ignores pending operations. This phase determines the health state.
    • + *
  • Phase 2 (Command Deduplication): Calls isSufficientlyReplicated(true) + * which considers pending operations. This phase decides whether to enqueue + * new commands.
    • + *
+ * Since Recon only needs Phase 1 (health determination) and doesn't issue commands, + * the stub PendingOps does not cause false positives.

Processing Flow:

    + * + *

    Performance settings applied in this test

    + *
      + *
    • Page cache: {@code derby.storage.pageCacheSize = 20000} + * (~80 MB of 4-KB pages) keeps hot B-tree nodes in memory, reducing + * filesystem reads even with the file-based Derby driver.
      • + *
    • JDBC fetch size: set to {@value #READ_PAGE_SIZE} on each query + * so Derby pre-buffers a full page of rows per JDBC round-trip instead + * of the default 1-row-at-a-time fetch.
      • + *
    • Large page size: {@value #READ_PAGE_SIZE} rows per SQL fetch + * reduces the number of SQL round-trips from 200 (@ 1 K rows) to 40 + * (@ 5 K rows) per 200 K-row state scan.
      • + *
    • Large delete chunks: {@value #DELETE_CHUNK_SIZE} IDs per + * DELETE statement reduces Derby plan-compilation overhead from 100 + * statements to 20 for a 100 K-ID batch delete.
      • + *
    + * + *

    What is measured

    + *
      + *
    1. Bulk INSERT throughput – 1 M records via JOOQ batchInsert in + * chunks of 1,000 inside a single Derby transaction.
      2. + *
    2. COUNT(*) by state – index-covered aggregate, one per state.
      3. + *
    3. GROUP BY summary – single pass over the idx_container_state + * index to aggregate all states.
      4. + *
    4. Paginated SELECT by state – cursor-style walk using + * minContainerId / maxContainerId to fetch the full 200 K rows of one + * state in pages of {@value #READ_PAGE_SIZE}, without loading all rows + * into the JVM heap at once.
      5. + *
    5. Batch DELETE throughput – removes records for half the + * container IDs (100 K × 5 states = 500 K rows) via a single + * IN-clause DELETE.
      6. + *
    + * + *

    Design notes

    + *
      + *
    • Derby is an embedded, single-file Java database — not designed for + * production-scale workloads. Performance numbers here document its + * baseline behaviour and will flag regressions, but should not be + * compared with PostgreSQL / MySQL numbers.
      • + *
    • Timing thresholds are deliberately generous (≈ 10× expected) to be + * stable on slow CI machines. Actual durations are always logged.
      • + *
    • Uses {@code @TestInstance(PER_CLASS)} so the 1 M-row dataset is + * inserted exactly once in {@code @BeforeAll} and shared across all + * {@code @Test} methods in the class.
