This track allows to overwrite the following parameters with Rally 0.8.0+ using --track-params:

• bulk_size (default: 500)
• bulk_indexing_clients (default: 8): Number of clients that issue bulk indexing requests.
• ingest_percentage (default: 100): A number between 0 and 100 that defines how much of the document corpus should be ingested.
• conflicts (default: "random"): Type of id conflicts to simulate. Valid values are: 'sequential' (A document id is replaced with a document id with a sequentially increasing id), 'random' (A document id is replaced with a document id with a random other id).
• conflict_probability (default: 25): A number between 0 and 100 that defines the probability of id conflicts. This requires to run the respective challenge. Combining conflicts=sequential and conflict-probability=0 makes Rally generate index ids by itself, instead of relying on Elasticsearch's automatic id generation <https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-index_.html#_automatic_id_generation>_.
• on_conflict (default: "index"): Whether to use an "index" or an "update" action when simulating an id conflict.
• recency (default: 0): A number between 0 and 1 that defines whether to bias towards more recent ids when simulating conflicts. See the Rally docs for the full definition of this parameter. This requires to run the respective challenge.
• max_num_segments: The number of segments to target when doing a force merge (default: -1)
• number_of_replicas (default: 0)
• number_of_shards (default: 5)
• source_enabled (default: true): A boolean defining whether the _source field is stored in the index.
• index_settings: A list of index settings. Index settings defined elsewhere (e.g. number_of_replicas) need to be overridden explicitly.
• default_search_timeout (default: -1)
• cluster_health (default: "green"): The minimum required cluster health.
• error_level (default: "non-fatal"): Available for bulk operations only to specify ignore-response-error-level.
• post_ingest_sleep (default: false): Whether to pause after ingest and prior to subsequent operations.
• post_ingest_sleep_duration (default: 30): Sleep duration in seconds.
