Re: [openstack-dev] [All projects that use Alembic] Absence of pk on alembic_version table
On 01/24/2017 04:49 AM, Kirill Proskurin wrote: HI! Thing is, running Galera without enforcing it very bad idea for production use. Permissive mode was added more or less for testing purposes, running real production with it is dangerous, since it's not enforcing the mandatory Galera requirement, one of them is a "All tables must have a primary key". Any application that wishes to run Galera in PK-enforcing mode may do so, by simply adding a primary key constraint to the alembic_version table beforehand if one is not already present. Openstack applications may add a migration that does this automatically as well. But beyond that, I disagree with this characterization. Galera's documentation does not state "All tables must have a primary key", it states, "Do not use tables without a primary key", and the reasons they list do not affect Alembic's use case except in one potential edge case (although the documentation is too vague to know if it's real or not), for which the above workaround that the Openstack application add a PK constraint up front would mitigate. Reviewing Galera's documentation on this subject: http://galeracluster.com/documentation-webpages/limitations.html "Do not use tables without a primary key." OK, nevertheless they are giving us the choice. Let's see why that is: "When tables lack a primary key, rows can appear in different order on different nodes in your cluster. " The Alembic versioning table typically stores exactly one row, or in the case of an Openstack application using multiple branches like Neutron may store several rows, however there is no ordering requirement on this table when they are SELECTed. Additionally, relational database tables have no defined ordering in *any* case, so a SELECT that has no ORDER BY yet which expects a specific ordering is already broken. The other case for intrinsic ordering is that concurrent UPDATE statements on a table may produce different row locking behavior; so that an UPDATE applied to a table may apply differently depending on which galera node is accessed. This is a non-issue for the alembic version table because this table is only accessed by a single process during an upgrade operation and is not subject to any concurrency. "As such, queries like SELECT...LIMIT... can return different results." You should *never* run SELECT..LIMIT without an ORDER BY on any relational database so this point is moot. "Additionally, on such tables the DELETE statement is unsupported." Here we have the first issue that can be a problem. The alembic_version table is normally not subject to a DELETE operation. The feature in which DELETE is used is if a project is using branches that merge together - when an upgrade across a merge point is made, the additional rows in the table for the merged points are DELETEd. Currently, I'm not sure if any openstack project is merging any branches together. If they are, they should include a migration that manually adds a primary key constraint to the alembic_version table. That is, each Openstack project can address this issue directly just by including a migration that adds a primary key constraint to the alembic_version table. In my testing, I cannot locate the nature of the "is unsupported" statement. The DELETE statement does in fact work "fine" on a Galera cluster table that has no primary key, the correct row is deleted and the correct result is replicated to the other nodes. So if "unsupported" means, "may fail under load", "doesn't work with the AUTO_INCREMENT feature" (which Alembic does not use) "may fail randomly", or simply, "works fine we just don't want to test it", is not clear. But again, the upstream Alembic fix isn't as essential as much as it is that a project that is merging branches together makes sure they perform an ALTER against the alembic_version table to add a primary key constraint if one does not exist already. "Note - If you have a table without a primary key, it is always possible to add an AUTO_INCREMENT column to the table without breaking your application. " this cryptic statement suggests that perhaps Galera's AUTO_INCREMENT feature is the concern they have with DELETE. Alembic does not use the AUTO_INCREMENT feature on this table. Overall, Galera's notes on this subject do not indicate that an application with an un-constrained alembic_version table is dangerous in any way, with the possible exception of a branch merge operation for which the risk can be mitigated by adding the primary key constraint to the table.Additional detail as to the "DELETE is not supported" comment would be helpful. You cant disable a single check, you could only disable them all and this could lead to some serious problems, like data loss or corruption. If OS wants support Galera, it needs to comply with the Galera requirements. On Mon, Jan 23, 2017 at 9:59 PM, Ihar Hrachyshka

Re: [openstack-dev] [All projects that use Alembic] Absence of pk on alembic_version table
Nope, this won't be necessary. 0.8.10 - allows us to create pk on alembic_version table automatically, but only for new deployments. I propose manually add pk on this table if it is not existing.

Re: [openstack-dev] [All projects that use Alembic] Absence of pk on alembic_version table
We do not backport db changes, but if the existing migration does not work in certain circumstances, should not we fix it to make it work if it is possible? This will allow to deploy new deployments with Newton code on Galera.

Re: [openstack-dev] [All projects that use Alembic] Absence of pk on alembic_version table
HI! Thing is, running Galera without enforcing it very bad idea for production use. Permissive mode was added more or less for testing purposes, running real production with it is dangerous, since it's not enforcing the mandatory Galera requirement, one of them is a "All tables must have a primary key". You cant disable a single check, you could only disable them all and this could lead to some serious problems, like data loss or corruption. If OS wants support Galera, it needs to comply with the Galera requirements.

Re: [openstack-dev] [All projects that use Alembic] Absence of pk on alembic_version table
An alternative could also be, for Newton and earlier, to release a note saying that operators should not run the code against ENFORCING galera mode. What are the reasons to enable that mode in OpenStack scope that would not allow operators to live without it for another cycle?

[openstack-dev] [All projects that use Alembic] Absence of pk on alembic_version table
Hello everyone! Guys in our team faced an issue when they try to run alembic migrations on Galera with ENFORCING mode. [1] This was an issue with Alembic [2], which was quickly fixed by Mike Bayer (many thanks!) and new version of alembic was resealed [3]. The global requirements are updated [4]. I think that it is desired to fix this for Newton at least. We cannot bump requirements for Newton, so hot fix can be putting pk on this table in the first migration like proposed [5].
