Vladimir Ozerov created IGNITE-9310: ---------------------------------------
Summary: SQL: throw exception when missing cache is attempted to be created inside a transaction Key: IGNITE-9310 URL: https://issues.apache.org/jira/browse/IGNITE-9310 Project: Ignite Issue Type: Task Components: mvcc, sql Affects Versions: 2.6 Reporter: Vladimir Ozerov Fix For: 2.7 See \{{org.apache.ignite.internal.processors.query.h2.IgniteH2Indexing#prepareStatementAndCaches}}. This method might be called inside a transaction (both MVCC and non-MVCC modes). If we do not have any protective mechanics (need to check), then this call may lead to cache creation on a client, which in turn will wait for all TXes to finish, including current one, leading to a deadlock. # Create tests confirming the problem # If hang is reproduced - add a check for ongoing transaction and throw an exception -- This message was sent by Atlassian JIRA (v7.6.3#76005)
