supports standard SQ
Doris uses a columnar storage engine, which encodes, compresses, and reads
data by column. This enables a very high compression ratio and largely reduces
irrelavant data scans, thus making more efficient use of IO and CPU resources.
Doris supports various index structures to minimize data scans:
- Sorted Compound Key Index: Users can specify three columns at most to form a
compound sort key. This can effectively prune data to better support highly
concurrent reporting scenarios.
-- Z-order Index: This allows users to efficiently run range queries on any
combination of fields in their schema.
- MIN/MAX Indexing: This enables effective filtering of equivalence and range
queries for numeric types.
- Bloom Filter: very effective in equivalence filtering and pruning of high
cardinality columns
- Invert Index: This enables fast search for any field.
