Return decoded data to spark 9

10 Lazy Decoding by Leveraging Global Dictionary SELECT c1, sum(c2) FROM t1 WHERE c3>10 group by c1 Stage 2 Original plan Stage 2 Optimized plan Dictionary Decode Decode c1 in last stage Stage 1 Aggregation Stage 1 Aggregation Groupby on encoded value of c1 Filter Filter Scan (decode c1, c2, c3) Scan (decode c2, c3 only) 10

11 Query Package And Interface Query RDD org.apache.carbondata.spark.rdd.carbonscanrdd-query execution rdd Query Executor Interface org.apache.carbondata.core.scan.executor.queryexecutor- Carbon query interface org.apache.carbondata.core.scan.result.iterator.abstractdetailqueryresultiterator- Internal query interface, execute the query return the iterator over query result Scanner Interface org.apache.carbondata.core.scan.processor.abstractdatablockiterator- iterator to process the blocklet 11

12 Query Package And Interface Scanner Interface org.apache.carbondata.core.scan.scanner.scanner- Interface for scanning the blocklet, there are two type of scanner non filter scanner and filter scanner. org.apache.carbondata.core.scan.filter.executer.filterexecuter -Interface for executing the filter in executor side org.apache.carbondata.core.scan.collector.scannedresultcollector - Prepares the query results from scanned result Reader Interface org.apache.carbondata.core.datastore.chunk.reader.dimensioncolumnchunkreader- Reader interface for reading and uncompressing the blocklet dimension column data. Reader returns the store instance based on column type 12

13 Query Package And Interface Reader Interface org.apache.carbondata.core.datastore.chunk.reader.measurecolumnchunkreader- Reader interface for reading and uncompressing the blocklet measure column data. Reader returns the store instance based on column data type Query Data Store Interface org.apache.carbondata.core.datastore.chunk.store.dimensiondatachunkstore- Interface for storing the uncompressed dimension column data during query org.apache.carbondata.core.datastore.chunk.store.
