toddstoffel can you help us with reproducing a test case. Can we get the source and target table definitions and preferably sample data that reproduces this if possible.

Comment by Dipti Joshi (Inactive) [ 2018-11-20 ]

dthompson, markus makela In my testing following are source and target table definition

@David, we just created a table to try this out, on both sides

Most likely already fixed by f156fb08c48442075de75e42dc64a22b68b5b5ff that was not merged into 1.1.6.

Try with these packages built from the 1.1.7 development version (commit 5aaec400cdf02bdcccd73a4fdd67d2ecf71df118): mariadb-columnstore-maxscale-cdc-adapters-1.1.7-1-x86_64-centos7.rpm

Comment by Andrew Hutchings (Inactive) [ 2018-11-21 ]

Problem is due to us compiling against an old version of MaxScale and therefore cdc_connector. This is not ABI compatible with the cdc_connector in 2.3.0.

We can't fix this by just upgrading MaxScale in buildbot because if the user upgrade to a future MaxScale with a newer cdc_connector it will break again for the user.

To fix this ColumnStore's data adapter tree needs to use a git submodule of MaxScale and compile cdc_connector in rather than linking.

Comment by Andrew Hutchings (Inactive) [ 2018-11-22 ]

Switched to compiling in cdc-connector

Comment by Zdravelina Sokolovska (Inactive) [ 2018-11-30 ]

checked with mxs_adapter and mcsapi v1.2.2-1 installed on max-scale server with v2.3.1-1 ,
crash was not recreated but it's received mxs_adapter was not able to connect the requested db.table

Comment by Dipti Joshi (Inactive) [ 2018-12-01 ]

This indicates that either

  • CDC user that you are using is not defined in MaxScale and source database
    OR
  • The port 4001 on MaxScale server is not accepting connection.
    Please provide maxscale.cnf from your MaxScale winstone
