This topic describes how to reduce index traffic fees by optimizing index configurations.
- Disable the full-text indexing feature and configure field indexes.
Log Service supports full-text indexes and field indexes.
- After you enable the full-text indexing feature, log field names (keys) and field values (values) are stored in the text type. Field names and values are included in index traffic.
- After you configure field indexes, field names of the long and double types are not included in index traffic. You can configure field indexes to reduce index traffic fees.
- Configure indexes only for some fields.
If raw logs contain a large number of fields and only some of the fields are used for query and analysis, you can create 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 lists examples.
Size of raw logs Index percentage Size of indexes 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 to use the LogReduce feature, disable the feature at your earliest opportunity. For more information, see LogReduce.
