Purlin.Elasticsearch

Index naming

Indices are declared by an index descriptor (e.g. searchable_listings), used both in IndexConfiguration.IndexDescriptor and in Repository<TId, TDocument>(indexDescriptor). The actual index name is resolved from ElasticsearchContextSettings:

  1. IndexNames[indexDescriptor] - an explicit name, if configured (keys are case-insensitive)
  2. {IndexPrefix}_{indexDescriptor} - if IndexPrefix is set
  3. indexDescriptor as is

Explicit names allow each index to be named independently, e.g. sharing some indices between environments while keeping others separate. The built-in migration_history and distributed_locks indices are resolved the same way.

"ElasticsearchContextSettings": {
  "Uri": "...",
  "ApiKey": "...",
  "IndexNames": {
    "searchable_listings": "pse_testing_searchable_listings",
    "migration_history": "pse_testing_migration_history",
    "distributed_locks": "pse_testing_distributed_locks"
  }
}

Cluster monitoring

ElasticsearchContext.ClusterMonitor exposes read-only cluster health checks, e.g. to apply backpressure before the cluster starts rejecting requests.

GetMemoryPressureAsync reads the JVM memory pressure of every node (GET _nodes/stats/jvm) - the old generation heap usage, the same metric Elastic Cloud uses for its "JVM memory pressure" alerts. Above ~75% garbage collection becomes aggressive, above ~85% circuit breakers start rejecting requests (circuit_breaking_exception). The call never throws for Elasticsearch or transport failures; check IsSuccess. It requires the monitor cluster privilege for the configured API key.

var memoryPressure = await context.ClusterMonitor.GetMemoryPressureAsync(cancellationToken: cancellationToken);

if (memoryPressure.IsSuccess && memoryPressure.MaxMemoryPressurePercent >= 75)
{
    // Slow down background writes
}
