Simple Log Service:How do I reduce index traffic fees?

You can use the following optimization methods to reduce index traffic fees when you use Simple Log Service. For more information, see Create indexes.

• Disable the full-text indexing feature and configure field indexes.

  Simple Log Service supports full-text indexes and field indexes.

  • If you configure full-text indexes, all field names and field values of logs are stored as text. The field names and field values are both included in the index traffic. Field names and field values form key-value pairs.

  • If you configure field indexes, field names of the long and double types are not included in the index traffic. You can use field indexes to reduce index traffic fees. Example:

    • If you configure an index of the text type for the request_uri field and the field value is /request/path-2/file-7, the string request_uri and the value /request/path-2/file-7 are both included in the index traffic.

• Configure indexes only for important fields.

  If raw logs contain a large number of fields and only some of the fields are used for query and analysis, you can configure indexes only for these fields.

• Disable LogReduce.

  After you enable the LogReduce feature, the total size of index traffic increases by 10%. The following table provides some examples.

  Size of raw logs	Index percentage	Size of index traffic generated by LogReduce	Total index traffic
  100 GB	20% (20 GB)	100 GB×10%	30 GB
  100 GB	40% (40 GB)	100 GB×10%	50 GB
  100 GB	100% (100 GB)	100 GB×10%	110 GB

  If you no longer need the LogReduce feature, disable the feature at the earliest opportunity. For more information, see LogReduce.
