- Speed up partitioning on commit by only recording partition boundaries instead of copying the whole table with a partition ID on each row
- Also write partitions in multiple threads
- Add a size-per-row estimate to the LQ planner.
- Add some helper functions to run a dbt transformation from Git against a single schema (clone, patch the dbt project)
- Add ability to choose a different normalization mode when running Airbyte data sources, in line with the Airbyte runner itself:
- none: only produce _raw tables
- basic: Airbyte's basic normalization
- custom: Git URL to a custom dbt project that converts the _raw tables.
…only making a temporary table with chunk boundaries (instead of copying every row and its chunk ID over into a temporary table).
…when running the commit.
…n (since only the raw tables depend on it).
…ph (get a repo, patch its data sources to point to the same schema).
…rmalization and pass in a custom Git repo with a dbt project. Note that downstream users inheriting from this data source should merge the `params_schema`/`credentials_schema` using the `merge_jsonschema` function.
…e AB normalization, as well as a test for no normalization at all.
… it so that other threads that chunk the table up can see it (since they use different PG connections).
…avoid corner cases with PK-less tables having NULLs in them and breaking comparisons.
…g to load any rows at all.
… row to text) if there's no PK and make sure to do it consistently (order by this PK and filter by it too when partitioning).
