Index entries such as cp_content_override_key_id_for_cs_idx where hand created by the customer. Satellite is now providing providing equivalent indexes. As the customer created the original index by hand, if the customer does not wish to have duplicate indexes for the same fields, the customer should delete the indexes that they created. Moving to new as there were 2 other pairs of indexes that are worth considering cleanup: cp_pool_source_stack_pool_ukey & idx_sourcestack_pool_fk cp_dist_version_pkey & cp_dist_version_id_idx The Candlepin bz has been closed, and the fix has been released in candlepin-2.10.0-1 (current master). This will be included in Sat 6.8 Steps to retest: 1. ssh into satellite 2. Run command: su - postgres -c "psql -d candlepin -c 'SELECT indrelid::regclass AS TableName,array_agg(indexrelid::regclass) AS Indexes FROM pg_index GROUP BY indrelid,indkey HAVING COUNT(*) > 1;;'" Expected result: o duplicates in db Actual result: tablename | indexes -----------+--------- (0 rows) Verified on 6.7.0_05. I've already checked using su - postgres -c "psql -d candlepin -c 'SELECT indrelid::regclass AS TableName,array_agg(indexrelid::regclass) AS Indexes FROM pg_index GROUP BY indrelid,indkey;;'" and saw that there's no duplicate.

Description of problem: There are multiple duplicate indexes present in candlepin database. Having identical indexes means the DB is spending more time updating two indexes when only one needs to be updated. Duplicate indexes should be cleaned up and there should be a workaround to cleanup indexes in the current version. We should remove the unwanted indexes during the upgrades In Customer DB, these are the duplicate indexes are present in the DB size | idx1 | idx2 --------+---------------------------------------+-------------------------- 262 MB | cp_content_override_key_id_for_cs_idx | cp_content_override_idx1 576 kB | cp_pool_source_stack_pool_ukey | idx_sourcestack_pool_fk 32 kB | cp_dist_version_pkey | cp_dist_version_id_idx In local environment Satellite 6.5(upgraded from 6.4) having below duplicate indexes #su - postgres -c "psql -d candlepin -c 'SELECT indrelid::regclass AS TableName,array_agg(indexrelid::regclass) AS Indexes FROM pg_index GROUP BY indrelid,indkey HAVING COUNT(*) > 1;;'" tablename | indexes ----------------------+---------------------------------------------------------- cp_dist_version | {cp_dist_version_id_idx,cp_dist_version_pkey} cp_pool_source_stack | {cp_pool_source_stack_pool_ukey,idx_sourcestack_pool_fk} (2 rows) Version-Release number of selected component (if applicable): 6.5 How reproducible: Always Steps to Reproduce: 1. Try to find duplicate indexes using SQL query as per summary Actual results: There are multiple duplicates indexes Expected results: Duplicate indexes should not be present
