I have an index with an parent child structure. When I try to run a "race" with it in esrally I get 100 percent error rate. As shown bellow: | Metric | Task | Value | Unit | | --- | --- | --- | --- | | Cumulative indexing time of primary shards | | 0 | min | | Min cumulative indexing time across primary shards | | 0 | min | | Median cumulative indexing time across primary shards | | 0 | min | | Max cumulative indexing time across primary shards | | 0 | min | | Cumulative indexing throttle time of primary shards | | 0 | min | | Min cumulative indexing throttle time across primary shards | | 0 | min | | Median cumulative indexing throttle time across primary shards | | 0 | min | | Max cumulative indexing throttle time across primary shards | | 0 | min | | Cumulative merge time of primary shards | | 0 | min | | Cumulative merge count of primary shards | | 0 | | | Min cumulative merge time across primary shards | | 0 | min | | Median cumulative merge time across primary shards | | 0 | min | | Max cumulative merge time across primary shards | | 0 | min | | Cumulative merge throttle time of primary shards | | 0 | min | | Min cumulative merge throttle time across primary shards | | 0 | min | | Median cumulative merge throttle time across primary shards | | 0 | min | | Max cumulative merge throttle time across primary shards | | 0 | min | | Cumulative refresh time of primary shards | | 0 | min | | Cumulative refresh count of primary shards | | 2 | | | Min cumulative refresh time across primary shards | | 0 | min | | Median cumulative refresh time across primary shards | | 0 | min | | Max cumulative refresh time across primary shards | | 0 | min | | Cumulative flush time of primary shards | | 0 | min | | Cumulative flush count of primary shards | | 0 | | | Min cumulative flush time across primary shards | | 0 | min | | Median cumulative flush time across primary shards | | 0 | min | | Max cumulative flush time across primary shards | | 0 | min | | Total Young Gen GC time | | 0 | s | | Total Young Gen GC count | | 0 | | | Total Old Gen GC time | | 0 | s | | Total Old Gen GC count | | 0 | | | Store size | | 1.93715e-07 | GB | | Translog size | | 5.12227e-08 | GB | | Heap used for segments | | 0 | MB | | Heap used for doc values | | 0 | MB | | Heap used for terms | | 0 | MB | | Heap used for norms | | 0 | MB | | Heap used for points | | 0 | MB | | Heap used for stored fields | | 0 | MB | | Segment count | | 0 | | | Min Throughput | bulk | 24.64 | docs/s | | Median Throughput | bulk | 24.64 | docs/s | | Max Throughput | bulk | 24.64 | docs/s | | 50th percentile latency | bulk | 28.8184 | ms | | 100th percentile latency | bulk | 116.64 | ms | | 50th percentile service time | bulk | 28.8184 | ms | | 100th percentile service time | bulk | 116.64 | ms | | error rate | bulk | 100 | % | I am suppose to specify the number of parent documents If i understood [esrally documentation](https://esrally.readthedocs.io/en/stable/track.html?highlight=parent#corpora). That might be the issue, but how do I do that? ---

Is there anything in the Rally logs? What does your track look like? ---

Your corpora only contains 83 documents which will not even fill one bulk request. The issue is therefore that the track finishes before warmup is completed which leaves no requests to be measured. ---
