Error "countRows is not yet supported." on AWS Keyspaces

[pasarbia]

Hello, We have the following error when integrating the extension to AWS Keyspaces. The AWS support responded that Keyspaces does not have a plan to support "count". Is there a way to manage this error on the Liquibase side?

I submitted a proposal for a fix. It's not optimal because it requires to execute a SELECT * query in replacement of the SELECT COUNT(*) one, then counting the rows in the returned list. But I think this should solve the issue.

@filipelautert @kevin-atx Do not hesitate to have a look to the fix proposal #292.

@pasarbia Based on the provided stacktrace, it seems it uses the standard implementation of Liquibase instead of the custom lock service for Cassandra.

at liquibase.lockservice.StandardLockService.isDatabaseChangeLogLockTableInitialized(StandardLockService.java:219) 
at liquibase.lockservice.StandardLockService.init(StandardLockService.java:135)

But I expected here a call to: liquibase.ext.cassandra.lockservice.LockServiceCassandra.isDatabaseChangeLogLockTableInitialized() Are you sure liquibase-cassandra is correctly loaded in your classpath?

[pasarbia]

is it possible that the countRows query comes from the driver?

@pasarbia

I don't think it's related, but the JDBC URL here contains an error: liquibase.command.url=jdbc:cassandra://cassandra.eu-west-1.amazonaws.com:9142/keyspace?compliancemode=Liquibase&&configfile=/home/ubuntu/liquibase/lib/application.conf There are two & between Liquibase and configfile instead of only one. But I guess, this has no consequence.

I tried to move liquibase-cassandra-4.28.0-SNAPSHOT.jar from /lib directory

The result you obtained in this case seems consistent. It's correct to have this jar in the lib directory.

is it possible that the countRows query comes from the driver?

This query (SELECT COUNT(*) FROM fsp_core.DATABASECHANGELOGLOCK) comes from Liquibase, here in cassandra extension: https://github.com/liquibase/liquibase-cassandra/blob/07e62651f7cecabe909a07d2b27009ef7321e066/src/main/java/liquibase/ext/cassandra/lockservice/LockServiceCassandra.java#L156 The CQL query is sent as-is to the Cassandra (AWS keyspaces in your case) server by the driver. The InvalidQueryException returned by the driver indicates a syntactically correct but invalid query, so it clearly comes from AWS keyspaces which does not support COUNT function. Consequently, it seems unlikely that the issue comes from the driver.

I guess you built liquibase-cassandra-4.28.0-SNAPSHOT.jar by yourself. Are you sure the built jar is correct and includes the changes?

[pasarbia]

liquibase-cassandra.log

@maximevw I modified the JDBC URL and the result is the same, as expected. The build jar was created with mvn clean package from main branch. I also decompiled the artifact and checked that the changes are there. I have no idea why it uses the standard implementation of Liquibase instead of the custom lock service for Cassandra. I attached the whole log, hopefully can help you help me. :)

[maximevw]

@pasarbia

There is something surprising in the logs you provided, the loaded jar for liquibase-cassandra is : /home/ubuntu/liquibase/lib/liquibase-cassandra-4.27.0.jar but previously you indicated this path /home/ubuntu/liquibase/lib/liquibase-cassandra-4.28.0-SNAPSHOT.jar, but maybe you just renamed the jar.

Anyway, I think I finally found the root cause of the issue: In StandardLockService, we have this line 135: if (!isDatabaseChangeLogLockTableInitialized(createdTable, true)) { But the problem is in LockServiceCassandra, only the method isDatabaseChangeLogLockTableInitialized(boolean tableJustCreated) is overridden. So, here, it still calls a method from StandardLockService including a COUNT(*) instead of a patched method in LockServiceCassandra.

Consequently, a complementary patch is needed to also override the method isDatabaseChangeLogLockTableInitialized(boolean tableJustCreated, boolean forceRecheck) in LockServiceCassandra. I'll try to provide this asap.

@filipelautert @rberezen Could you have a look to the PR #296 please?

This should fix the issue described in the last messages. I locally tested and it's now walking through the expected code path (previous patch #292).

[pasarbia]

@maximevw I’m grateful for your help!! The good news is that I don't have the count rows issue, so your code is working!! Unfortunately, now I have: [2024-05-17 14:19:48] FINE [liquibase.ext] Failed to create or initialize the lock table, trying again, iteration 1 of 10 liquibase.exception.DatabaseException: liquibase.exception.DatabaseException: com.datastax.oss.driver.api.core.servererrors.InvalidQueryException: TRUNCATE TABLE is not yet supported.

I hope you don't get bored with this. liquibase-cassandra-truncate.log

[maximevw]

@pasarbia Oh! It seems AWS keyspaces is not really friendly with Liquibase-Cassandra. 😄

There is here probably a little bit more work to do in order to be compliant with all the restrictions imposed by AWS Keyspaces.

To fix the TRUNCATE issue, it will be neccessary to develop another workaround (like for the rows count): replacing all the truncat queries by DROP TABLE + re-CREATE TABLE.

And ideally a deeper analysis of all the queries potentially not compatible with AWS keyspaces should be performed to prevent other similar issues.

[maximevw]

As this issue is closed and the incompatibility problem is large enough finally, I created a dedicated issue: https://github.com/liquibase/liquibase-cassandra/issues/297
