feat: social_snapshots, posts engagement columns, apify_scraper_runs lineage (app#2018) - #65
Conversation
…lineage (app#2018)
- social_snapshots: one follower point per social per UTC day, unique
(social_id, captured_on), RLS, backfill from socials.followerCount +
updated_at so history starts today.
- posts: views/likes/comments/reposts (nullable BIGINT); drop the
set_updated_at trigger so re-scrapes that refresh engagement keep the
publish timestamp the handlers write.
- apify_scraper_runs: origin ('artist'|'fan'), parent_run_id, account_id
nullable, indexes for the lineage walk and the per-account hourly count.

📝 WalkthroughWalkthroughThe migrations add daily social follower snapshots, post engagement counters, and scraper run lineage metadata. They also add supporting constraints, indexes, UTC date derivation, RLS, backfill logic, and timestamp-trigger changes. ChangesScraper data model

PostgreSQL CREATE INDEX regular blocks INSERT UPDATE DELETE CREATE INDEX CONCURRENTLY transaction Supabase migrations official documentation
💡 Result:
In PostgreSQL, the CREATE INDEX command and its concurrent counterpart have distinct locking behaviors that impact database availability [1][2]. Standard CREATE INDEX: When you run a standard CREATE INDEX command, PostgreSQL acquires a SHARE lock on the table [2]. This lock allows concurrent SELECT operations but blocks all write operations, including INSERT, UPDATE, and DELETE [1][2]. On large tables, this can cause significant downtime as the command must complete its scan and build before releasing the lock [1][3]. CREATE INDEX CONCURRENTLY: The CREATE INDEX CONCURRENTLY command is designed for production environments where downtime must be avoided [1]. It acquires a SHARE UPDATE EXCLUSIVE lock, which does not block INSERT, UPDATE, or DELETE operations, allowing regular table activity to continue [2][4][5]. Key constraints and trade-offs for CONCURRENTLY: 1. Transactional Limitations: CREATE INDEX CONCURRENTLY cannot be executed within a user-defined transaction block (e.g., BEGIN ... COMMIT) [6][7]. If included in a migration file, it must be the only command in that file or executed as a standalone statement [7]. 2. Performance and Duration: Because it performs two scans of the table and must wait for existing transactions to terminate, it takes significantly longer to complete (typically 2-3x longer) and consumes more CPU and I/O resources than a standard index build [1][2]. 3. Validity: If a concurrent index build fails (e.g., due to a constraint violation), it leaves behind an "invalid" index, which should be dropped and recreated [7]. Supabase Migrations Best Practices: For Supabase projects, official and community-recommended practices emphasize using CONCURRENTLY for all index creations in production to ensure zero-downtime [8][9][3]. - Use IF NOT EXISTS to ensure the migration is idempotent, though be aware of the "invalid index" risk mentioned above [7][9]. - Because CONCURRENTLY cannot run inside a transaction, keep migration files simple, ideally containing only the index creation statement [7]. - Always verify the index status (e.g., checking pg_index.indisvalid) after the migration has run [7].

Avoid blocking writes while building these indexes.
These standard CREATE INDEX statements can block INSERT, UPDATE, and DELETE operations on public.apify_scraper_runs until each build completes. If writes must continue, use CREATE INDEX CONCURRENTLY or run the migration during a maintenance window. If the migration runner uses a transaction, split the index builds into transaction-free migrations because CREATE INDEX CONCURRENTLY cannot run inside a transaction.

…m persisted, engagement + follower snapshots (app#2018) (#866) * feat(apify): scrape persistence keystone — one hop, every dataset item persisted, engagement + follower snapshots (app#2018) Guard: every run's webhook payload carries origin (artist|fan) + parentRunId via payloadTemplate; the Instagram profile handler continues (Arweave avatar, posts, social_posts, comments follow-up) only for origin=artist AND a profile linked to an account. Fan batches and legacy payloads without origin are terminal. The dataset.length === 1 heuristic is gone. Enrichment: the Instagram profile handler upserts EVERY profile in the dataset (avatar, bio, follower/following/post counts), so a 12-fan batch enriches 12 fans, not one. Posts: YouTube videos + Shorts persist via persistPostsForSocial; the LinkedIn posts actor (A3cAPGpwBEG8RJwse, what ?posts=N runs, previously unregistered) gets a handler; every post row carries views/likes/comments/reposts where the platform reports them; upsertPosts merges on post_url so re-scrapes refresh engagement; GET /api/artists/{id}/posts returns the four fields. Snapshots: upsertSocialsWithSnapshot is the one socials write path all eight handlers use; it appends a social_snapshots point per social per day whenever a follower count is present. GET /api/artists/{id}/socials?history=<days> returns them newest first. Lineage: both scrape routes register the root run; every spawned comments / commenter run is registered with parent_run_id, inheriting the root's account. Contract: recoupable/docs#316. Schema: recoupable/database#65. * fix(apify): review — posts merge never nulls a stored count, snapshot captured_at refreshed on same-day re-scrape, chunked history read, Instagram post dates via toIsoDate, root registration never throws, artist path reuses the upsert's rows * fix(apify): YouTube handler skips the leading /about error item the actor emits with a posts depth (found on preview: run FyKpfOPuDsv4zSeRz persisted nothing)
