- moved from grid to flexbox
- calculate Explore results only when query transactions change to prevent expensive re-renders
- split up rendering of graph and log data
- render log results in 2 stages
- Queries in Explore have been string based
- This PR introduces the use of the DataQuery type to denote all queries handled in Explore
- Within Explore all handling of DataQueries is transparent
- Modifying DataQueries is left to the datasource
- Using `target` as variable names for DataQueries to be consistent with the rest of Grafana
Existing querying was grouped together before handed over to the
datasource. This slowed down result display to however long the slowest
query took.
- create one query transaction per result viewer (graph, table, etc.)
and query row
- track latencies for each transaction
- show results as soon as they are being received
- loading indicator on graph and query button to indicate that queries
are still running and that results are incomplete
- properly discard transactions when removing or changing queries
