## Query best practices
- Use time filters first. Kusto is highly optimized to utilize time filters.
- Put filters that are expected to remove most of the data in the beginning of the query, following the time filter.
- Prefer 'has' keyword over 'contains' when looking for full tokens.
- Prefer looking in specific column rather than using full text search accross all columns.

- When joining between two tables - project only needed columns from both sides of the join.
