# Note
This repository contains the MATCH_RECOGNIZE query templates and scripts for
importing raw datasets into [Trino](https://trino.io/) (Hive + HDFS) and [PostgreSQL 14](https://www.postgresql.org/docs/14/index.html).
The raw CSV files for the datasets can be obtained from [here](https://github.com/sigmod2021-index-pattern/index-pattern).
Directory structure:
- query-templates:
- (benchmark dataset)
- (pattern definition)
- (pattern name).sql: MATCH_RECOGNIZE query with example parameters.
- scripts:
- hive_import_(dataset).sql: create tables in Hive after copying the raw CSV files into HDFS.
- trino_import_(dataset).sql: create tables in Trino from Hive tables.
- postgres_import_(dataset).sql: create tables in PostgreSQL from raw CSV files. [Citus](https://github.com/citusdata/citus) extension is required.
