cool, similar trick with citus_stat_activity :) I wish we had a single function to pull from different tables, but this is also good

DESCRIPTION: Adds views that monitor statistics on tenant usages This PR adds `citus_stats_tenants` view that monitors the tenants on the cluster. `citus_stats_tenants` shows the node id, colocation id, tenant attribute, read count in this period and last period, and query count in this period and last period of the tenant. Tenant attribute currently is the tenant's distribution column value, later when schema based sharding is introduced, this meaning might change. A period is a time bucket the queries are counted by. Read and query counts for this period can increase until the current period ends. After that those counts are moved to last period's counts, which cannot change. The period length can be set using 'citus.stats_tenants_period'. `SELECT` queries are counted as _read_ queries, `INSERT`, `UPDATE` and `DELETE` queries are counted as _write_ queries. So in the view read counts are `SELECT` counts and query counts are `SELECT`, `INSERT`, `UPDATE` and `DELETE` count. The data is stored in shared memory, in a struct named `MultiTenantMonitor`. `citus_stats_tenants` shows the data from local tenants. `citus_stats_tenants` show up to `citus.stats_tenant_limit` number of tenants. The tenants are scored based on the number of queries they run and the recency of those queries. Every query ran increases the score of tenant by `ONE_QUERY_SCORE`, and after every period ends the scores are halved. Halving is done lazily. To retain information a longer the monitor keeps up to 3 times `citus.stats_tenant_limit` tenants. When the tenant count hits `3 * citus.stats_tenant_limit`, last `citus.stats_tenant_limit` tenants are removed. To see all stored tenants you can use `citus_stats_tenants(return_all_tenants := true)` - [x] Create collector view that gets data from all nodes. #6761 - [x] Add monitoring log #6762 - [x] Create enable/disable GUC #6769 - [x] Parse the annotation string correctly #6796 - [x] Add local queries and prepared statements #6797 - [x] Rename to citus_stat_statements #6821 - [x] Run pgbench - [x] Fix role permissions #6812 --------- Co-authored-by: Gokhan Gulbiz <ggulbiz@gmail.com> Co-authored-by: Jelte Fennema <github-tech@jeltef.nl>
In this release, I tried something different. I experimented with adding the PR number and title to the changelog right before each changelog entry. This way, it is easier to track where a particular changelog entry comes from. After reviews are over, I plan to remove those lines with PR numbers and titles. I went through all the PRs that are merged after 11.2.0 release and came up with a list of PRs that may need help with changelog entries. You can see details on PRs grouped in several sections below. ## PRs with missing entries The following PRs below do not have a changelog entry. If you think that this is a mistake, please share it in this PR along with a suggestion on what the changelog item should be.
