Limit | Description |
File preview limits | Only files smaller than 1 GB can be previewed. |
Limit | Description |
Single File Size | The size of a single file cannot exceed 5 GB. If the limit is exceeded, the entire file will be ignored by the import task. |
Single Log Entry Size | The maximum size for a single-line log is limited to 512 KB. If the size of a log entry exceeds 512 KB, it will be truncated to retain only the first 512 KB. The maximum size for each log entry in multi-line logs is limited to 1 MB following division using the line-start regular expression. |
Regular Expression | The regular expression type supports Perl-compatible regular expressions. |
Collection Behavior When Log Parsing Fails | It is recommended to enable the upload on parsing failure feature, which ensures that logs that fail to be parsed are uploaded to the preset index in a single-line full-text format. If this feature is not enabled, logs with parsing failures will be discarded. |
Key Field Length | In delimiter and regular expression extraction modes, the maximum length of a Key field is 128 bytes. |
Number of Key-Value Pairs | In all parsing modes, the maximum number of extracted key-value pairs is 1,000. Any excess will be discarded. |
Performance Metric | Specification Description |
Throughput per partition | Maximum 5 MB/s. |
Maximum concurrency | Maximum 50 concurrent requests (total throughput 250 MB/s). |
