Function Item Limit Note
Query Number of keywords The number of conditions specified for querying words besides Boolean logical operators. You can query up to 30 keywords each time. For example, "a and b or c and d...".
The length of a single value. The maximum length of a single value is 10 KB. The excess part of the value is not queried. If the length of a single value is greater than 10 KB, the log might not be found through keywords, but the data is still complete.
Single project concurrency The number of single project concurrency is up to 100. -
Number of entries of returned query results By default, a maximum of 100 entries of query results are returned each time. You can read the full query results by turning pages.
Single Log content display For logs exceeding 10,000 characters, Log service only processes the first 10,000 characters using the DOM word segmentation due to Web browser performance. If a log contains more than 10,000 characters, the system will display a corresponding prompt.
SQL analysis Maximum length of a single value The maximum length of a single value is 2 KB. The excess part of the value is not queried. Query results might not be accurate when the limit is exceeded, but the data is still complete.
Single project concurrency The number of single project concurrency is up to 15. -
Number of entries of results in each analysis
  • By default, 100 log entries are displayed after an SQL statement is executed.
  • The returned result of each analysis can be log entries of 100 MB or 100,000 log entries at most.

You can use the limit parameter to specify the number of returned log entries.

You can turn over the page to view the returned results.
Field size The size of a field used in a statement can be up to 2 KB. The system truncates a field larger than 2 KB.
Double precision A double type can be shown by using up to 52 digits. If you use more than 52 digits to show a double type, the precision will be affected. For example, 0.1+0.2 is shown as 0.30000000000000004. We recommend that you use round(0.1+0.2,2) to take two significant values.
