Utilities for simplifying development and testing:
-
Apache Arrow Flight manager testing script written in Python 3 to test the different endpoints of the ModelarDB manager Apache Arrow Flight API.
-
Apache Arrow Flight server testing script written in Python 3 to test the different endpoints of the ModelarDB server Apache Arrow Flight API.
-
Apache Parquet loading script written in Python 3 to read Apache Parquet files with equivalent schemas, create a model table with a matching schema if it does not exist, and load their data into the created table.
-
ModelarDB change evaluator script written in Python 3 to evaluate what impact a set of changes has on ModelarDB in terms of ingestion time, query processing time, and the amount of storage required. The script automatically computes and evaluates all possible combinations for the set of changes.
-
ModelarDB compression evaluator script written in Python 3 to evaluate how well ModelarDB compresses a data set stored in Apache Parquet files with the same schema for a set of error bounds. For each error bound the script automatically ingests the data set and computes metrics that indicate how well ModelarDB compressed the data set.
-
Git Hooks written in different scripting languages to ensure that the state of a repository is correct before or after a specific action has been performed.
-
ModelarDB evaluator written in Rust to evaluate how well ModelarDB compresses a data set stored in Apache Parquet files with the same schema for a set of error bounds. For each error bound the script automatically ingests the data set and computes metrics that indicate how well ModelarDB compressed the data set.
-
MQTT simulator written in Python 3 to simulate the sending of packets from sensors or devices to a broker. The simulator was originally forked from DamascenoRafael/mqtt-simulator.
-
ModelarDB compression profiler script written in Python 3 to compute how much storage each part of ModelarDB's compressed format uses at the logical database, table, and column level when stored in Apache Parquet files ordered by
univariate_idandstart_timeand compressed using Zstandard.
