From 6502dfae343850f510471b72ebece1c1329343e0 Mon Sep 17 00:00:00 2001 From: Robin Appelman Date: Thu, 7 Oct 2021 16:11:49 +0200 Subject: add better index for finding unindexed paths for the following query 'SELECT "path" FROM "oc_filecache" WHERE ("storage" = $storage) AND ("size" < 0) ORDER BY "fileid" DESC LIMIT 1;' currently the database will in some cases decide to priorize the sort by fileid over the filter when picking what index to use, resulting in a much slower query. by creating an index that allows first sorting by fileid and also filter by storage and size this case will be greatly sped up Signed-off-by: Robin Appelman --- core/Command/Db/AddMissingIndices.php | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'core/Command') diff --git a/core/Command/Db/AddMissingIndices.php b/core/Command/Db/AddMissingIndices.php index 2e6b3dc9aeb..c4360157f72 100644 --- a/core/Command/Db/AddMissingIndices.php +++ b/core/Command/Db/AddMissingIndices.php @@ -144,6 +144,13 @@ class AddMissingIndices extends Command { $updated = true; $output->writeln('Filecache table updated successfully.'); } + if (!$table->hasIndex('fs_id_storage_size')) { + $output->writeln('Adding additional size index to the filecache table, this can take some time...'); + $table->addIndex(['fileid', 'storage', 'size'], 'fs_id_storage_size'); + $this->connection->migrateToSchema($schema->getWrappedSchema()); + $updated = true; + $output->writeln('Filecache table updated successfully.'); + } } $output->writeln('Check indices of the twofactor_providers table.'); -- cgit v1.2.3
