+# Sparse Keyspace for Relation Directories
+
+## Summary
+
+This is an RFC describing a new storage strategy for storing relation directories.
+
+## Motivation
+
+Postgres maintains a directory structure for databases and relations. In Neon, we store these information
+by serializing the directory data in a single key (see `pgdatadir_mapping.rs`).
+
+```rust
+// DbDir:
+// 00 00000000 00000000 00000000 00   00000000
+
+// RelDir:
+// 00 SPCNODE  DBNODE   00000000 00   00000001 (Postgres never uses relfilenode 0)
+```
+
+We have a dedicated structure on the ingestion path to serialize the relation directory into this single key.
+
+```rust
+#[derive(Debug, Serialize, Deserialize, Default)]
+pub(crate) struct RelDirectory {
+    // Set of relations that exist. (relfilenode, forknum)
+    //
+    // TODO: Store it as a btree or radix tree or something else that spans multiple
+    // key-value pairs, if you have a lot of relations
+    pub(crate) rels: HashSet<(Oid, u8)>,
+}
+```
+
+The current codebase has the following three access patterns for the relation directory.
+
+1. Check if a relation exists.
+2. List all relations.
+3. Create/drop a relation.
+
+For (1), we currently have to get the reldir key, deserialize it, and check whether the relation exists in the
+hash set. For (2), we get the reldir key and the hash set. For (3), we need first to get
+and deserialize the key, add the new relation record to the hash set, and then serialize it and write it back.
+
+If we have 100k relations in a database, we would have a 100k-large hash set. Then, every
+relation created and dropped would have deserialized and serialized this 100k-large hash set. This makes the
+relation create/drop process to be quadratic. When we check if a relation exists in the ingestion path,
+we would have to deserialize this super big 100k-large key before checking if a single relation exists.
+
+In this RFC, we will propose a new way to store the reldir data in the sparse keyspace and propose how
+to seamlessly migrate users to use the new keyspace.
+
+The PoC patch is implemented in [PR10316](https://github.com/neondatabase/neon/pull/10316).
+
+## Key Mapping
+
+We will use the recently introduced sparse keyspace to store actual data. Sparse keyspace was proposed in
+[038-aux-file-v2.md](038-aux-file-v2.md). The original reldir has one single value of `HashSet<(Oid, u8)>`
+for each of the databases (identified as `spcnode, dbnode`). We encode the `Oid` (`relnode, forknum`),
+into the key.
+
+```plain
+(REL_DIR_KEY_PREFIX, spcnode, dbnode, relnode, forknum, 1) -> deleted
+(REL_DIR_KEY_PREFIX, spcnode, dbnode, relnode, forknum, 1) -> exists
+```
+
+Assume all reldir data are stored in this new keyspace; the 3 reldir operations we mentioned before can be
+implemented as follows.
+
+1. Check if a relation exists: check if the key maps to "exists".
+2. List all relations: scan the sprase keyspace over the `rel_dir_key_prefix`. Extract relnode and forknum from the key.
+3. Create/drop a relation: write "exists" or "deleted" to the corresponding key of the relation. The delete tombstone will
+   be removed during image layer generation upon compaction.
+
+Note that "exists" and "deleted" will be encoded as a single byte as two variants of an enum.
+The mapping is implemented as `rel_tag_sparse_key` in the PoC patch.
+
+## Changes to Sparse Keyspace
+
+Previously, we only used sparse keyspaces for the aux files, which did not carry over when branching. The reldir
+information needs to be preserved from the parent branch to the child branch. Therefore, the read path needs
+to be updated accordingly to accommodate such "inherited sparse keys". This is done in
+[PR#10313](https://github.com/neondatabase/neon/pull/10313).
+
+## Coexistence of the Old and New Keyspaces
+
+Migrating to the new keyspace will be done gradually: when we flip a config item to enable the new reldir keyspace, the
+ingestion path will start to write to the new keyspace and the old reldir data will be kept in the old one. The read
+path needs to combine the data from both keyspaces.
+
+Theoretically, we could do a rewrite at the startup time that scans all relation directories and copies that data into the
+new keyspace. However, this could take a long time, especially if we have thousands of tenants doing the migration
+process simultaneously after the pageserver restarts. Therefore, we propose the coexistence strategy so that the
+migration can happen seamlessly and imposes no potential downtime for the user.
+
+With the coexistence assumption, the 3 reldir operations will be implemented as follows:
+
+1. Check if a relation exists
+   - Check the new keyspace if the key maps to any value. If it maps to "exists" or "deleted", directly
+    return it to the user.
+   - Otherwise, deserialize the old reldir key and get the result.
+2. List all relations: scan the sparse keyspace over the `rel_dir_key_prefix` and deserialize the old reldir key.
+   Combine them to obtain the final result.
+3. Create/drop a relation: write "exists" or "deleted" to the corresponding key of the relation into the new keyspace.
+   - We assume no overwrite of relations will happen (i.e., the user won't create a relation at the same Oid). This will be implemented as a runtime check.
+   - For relation creation, we add `sparse_reldir_tableX -> exists` to the keyspace.
+   - For relation drop, we first check if the relation is recorded in the old keyspace. If yes, we deserialize the old reldir key,
+    remove the relation, and then write it back. Otherwise, we put `sparse_reldir_tableX -> deleted` to the keyspace.
+   - The delete tombstone will be removed during image layer generation upon compaction.
+
+This process ensures that the transition will not introduce any downtime and all new updates are written to the new keyspace. The total
+amount of data in the storage would be `O(relations_modifications)` and we can guarantee `O(current_relations)` after compaction.
+There could be some relations that exist in the old reldir key for a long time. Refer to the "Full Migration" section on how to deal
+with them. Plus, for relation modifications, it will have `O(old_relations)` complexity until we do the full migration, which gives
+us `O(1)` complexity after fully opt-in the sparse keyspace.

+The process also implies that a relation will only exists either in the old reldir key or in the new sparse keyspace. It is not possible
+to have a table to be recorded in the old reldir key while later having a delete tombstone for it in the sparse keyspace at any LSN.
+
+We will introduce a config item and an index_part record to record the current status of the migration process.
+
+- Config item `enable_reldir_v2`: controls whether the ingestion path writes the reldir info into the new keyspace.
+- `index_part.json` field `reldir_v2_status`: whether the timeline has written any key into the new reldir keyspace.
+
+If `enable_reldir_v2` is set to `true` and the timeline ingests the first key into the new reldir keyspace, it will update
+`index_part.json` to set `reldir_v2_status` to `Status::Migrating`. Even if `enable_reldir_v2` gets flipped back to
+`false` (i.e., when the pageserver restarts and such config isn't persisted), the read/write path will still
+read/write to the new keyspace to avoid data inconsistency. This also indicates that the migration is one-way only:
+once v2 is enabled, the user cannot go back to v1.
+
+## Next Steps
+
+### Full Migration
+
+This won't be implemented in the project's first phase but might be implemented in the future. Having both v1 and
+v2 existing in the system would force us to keep the code to deserialize the old reldir key forever. To entirely deprecate this
+code path, we must ensure the timeline has no old reldir data.
+
+We can trigger a special image layer generation process at the gc-horizon. The generated image layers will cover several keyspaces:
+the old reldir key in each of the databases, and the new reldir sparse keyspace. It will remove the old reldir key while
+copying them into the corresponding keys in the sparse keyspace in the resulting image. This special process happens in
+the background during compaction. For example, assume this special process is triggered at LSN 0/180. The `create_image_layers`
+process discovers the following keys at this LSN.
+
+```plain
+db1/reldir_key -> (table 1, table 2, table 3)
+...db1 rel keys
+db2/reldir_key -> (table 4, table 5, table 6)
+...db2 rel keys
+sparse_reldir_db2_table7 -> exists
+sparse_reldir_db1_table8 -> deleted
+```
+
+It will generate the following keys:
+
+```plain
+db1/reldir_key -> () # we have to keep the key because it is part of `collect_keyspace`.
+...db1 rel keys
+db2/reldir_key -> ()
+...db2 rel keys
+
+-- start image layer for the sparse keyspace at sparse_reldir_prefix at LSN 0/180
+sparse_reldir_db1_table1 -> exists
+sparse_reldir_db1_table2 -> exists
+sparse_reldir_db1_table3 -> exists
+sparse_reldir_db2_table4 -> exists
+sparse_reldir_db2_table5 -> exists
+sparse_reldir_db2_table6 -> exists
+sparse_reldir_db2_table7 -> exists
+-- end image layer for the sparse keyspace at sparse_reldir_prefix+1
+
+# The `sparse_reldir_db1_table8` key gets dropped as part of the image layer generation code for the sparse keyspace.
+# Note that the read path will stop reading if a key is not found in the image layer covering the key range so there
+# are no correctness issue.
+```
+
+We must verify that no pending modifications to the old reldir exists in the delta/image layers above the gc-horizon before
+we start this process (We can do a vectored read to get the full key history of the old reldir key and ensure there are no more images
+above the gc-horizon). Otherwise, it will violate the property that "a relation will only exists either in the old reldir key or
+in the new sparse keyspace". After we run this migration process, we can mark `reldir_v2_status` in the `index_part.json` to
+`Status::Migrated`, and the read path won't need to read from the old reldir anymore. Once the status is set to `Migrated`, we
+don't need to add the key into `collect_keyspace` and therefore all of them will be removed from all future image layers.
+
+The migration process can be proactively triggered across all attached/detached tenants to help us fully remove the old reldir code.
+
+### Consolidate Relation Size Keys
+
+We have relsize at the end of all relation nodes.
+
+```plain
+// RelSize:
+// 00 SPCNODE  DBNODE   RELNODE  FORK FFFFFFFF
+```
+
+This means that computing logical size requires us to do several single-key gets across the keyspace,
+potentially requiring downloading many layer files. We could consolidate them into a single
+keyspace, improving logical size calculation performance.
+
+### Migrate DBDir Keys
+
+We assume the number of databases created by the users will be small, and therefore, the current way
+of storing the database directory would be acceptable. In the future, we could also migrate DBDir keys into
+the sparse keyspace to support large amount of databases.
