Ekaterina Dimitrova commented on CASSANDRA-19404: ------------------------------------------------- trunk CI results: * junit.framework.TestSuite.org.apache.cassandra.distributed.test.CASMultiDCTest.testLocalSerialLocalCommit - CASSANDRA-18851 * in-jvm tests crash - CASSANDRA-19239 * org.apache.cassandra.audit.AuditLoggerAuthTest - CASSANDRA-19443 I did not re-run the 5.0 CI as the changes to the test suggested during review did not change the test coverage or the patch. I just ensured the test still passes locally. If there is nothing else to be addressed, I can commit this tomorrow. > Unexpected NullPointerException in ANN+WHERE when adding rows in another > partition > ---------------------------------------------------------------------------------- > > Key: CASSANDRA-19404 > URL: https://issues.apache.org/jira/browse/CASSANDRA-19404 > Project: Cassandra > Issue Type: Bug > Components: Feature/Vector Search > Reporter: Stefano Lottini > Assignee: Ekaterina Dimitrova > Priority: Normal > Fix For: 5.0-rc, 5.x > > Time Spent: 0.5h > Remaining Estimate: 0h > > * *Bug observed on the Docker image 5.0-beta1* > * *Bug also observed on latest head of Cassandra repo (as of 2024-02-15)* > * _*(working fine on vsearch branch of datastax/cassandra, commit hash > 80c2f8b9ad5b89efee0645977a5ca53943717c0d)*_ > Summary: A query with _ann + where clause on a map + where clause on the > partition key_ starts erroring once there are other partitions in the table. > There are three SELECT statements in the repro minimal code below - the third > is where the error is triggered. > {code:java} > // reproduced with Dockerized Cassandra 5.0-beta1 on 2024-02-15 > ///////// > // SCHEMA > ///////// > CREATE TABLE ks.v_table ( > pk int, > row_v vector<float, 2>, > metadata map<text, text>, > PRIMARY KEY (pk) > ); > CREATE CUSTOM INDEX v_md > ON ks.v_table (entries(metadata)) > USING 'StorageAttachedIndex'; > CREATE CUSTOM INDEX v_idx > ON ks.v_table (row_v) > USING 'StorageAttachedIndex'; > ///////////////////////////// > // SELECT WORKS (empty table) > ///////////////////////////// > SELECT * FROM ks.v_table > WHERE metadata['map_k'] = 'map_v' > AND pk = 0 > ORDER BY row_v ANN OF [0.1, 0.2] > LIMIT 4; > ////////////// > // ADD ONE ROW > ////////////// > INSERT INTO ks.v_table (pk, metadata, row_v) > VALUES > (0, {'map_k': 'map_v'}, [0.11, 0.19]); > ///////////////////////////////////////////// > // SELECT WORKS (table has queried partition) > ///////////////////////////////////////////// > SELECT * FROM ks.v_table > WHERE metadata['map_k'] = 'map_v' > AND pk = 0 > ORDER BY row_v ANN OF [0.1, 0.2] > LIMIT 4; > ////////////////////////////////// > // ADD ONE ROW (another partition) > ////////////////////////////////// > INSERT INTO ks.v_table (pk, metadata, row_v) > VALUES > (10, {'map_k': 'map_v'}, [0.11, 0.19]); > ///////////////////////////////////////////////// > // SELECT BREAKS (table gained another partition) > ///////////////////////////////////////////////// > SELECT * FROM ks.v_table > WHERE metadata['map_k'] = 'map_v' > AND pk = 0 > ORDER BY row_v ANN OF [0.1, 0.2] > LIMIT 4; {code} > The error has this appearance in CQL Console: > {code:java} > ReadFailure: Error from server: code=1300 [Replica(s) failed to execute read] > message="Operation failed - received 0 responses and 1 failures: UNKNOWN from > /172.17.0.2:7000" info={'consistency': 'ONE', 'required_responses': 1, > 'received_responses': 0, 'failures': 1, 'error_code_map': {'172.17.0.2': > '0x0000'}} {code} > And the Cassandra logs have this to say: > {code:java} > java.lang.NullPointerException: Cannot invoke > "org.apache.cassandra.index.sai.iterators.KeyRangeIterator.skipTo(org.apache.cassandra.index.sai.utils.PrimaryKey)" > because "this.nextIterator" is null {code} > -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
