Hyperspace v0.2.0

We are excited to announce the release of Hyperspace 0.2.0!

Notable new features / improvements:

• Python APIs (#36): You can now manage/utilize Hyperspace indexes using Python APIs. Please checkout the user guide to get started.
• Support case-insensitive index column names (#78): The case sensitivity config in Spark (spark.sql.caseSensitive) is now respected when index column names are matched to find candidate indexes.
• New signature provider(#77): The signature provider has been updated to compute the signature of an arbitrary logical plan (in addition to the existing file-based signature) to be more flexible (e.g, an upcoming feature where you can create an index on any dataframes)
• FilterIndex rule improvement(#73): FilterIndex rule has been updated to match a logical plan where Project node is not present (e.g, SELECT * scenario).

Breaking changes:

In order to better support compatibility across Scala/Spark versions going forward, the team has decided to stop serializing logical plans with KyroSerializer and store the minimum info to reconstruct the original relation(#99). Thus, the indexes generated with v0.1.0 are not compatible with v0.2.0 and need to be reconstructed.

Thank you for trying it out and we look forward to your feedback!
