Warning: This update causes some API-breaking changes:

  • Changed metadata backend, which breaks tables written in earlier versions
  • Changed filtering for cols from cols=['like', <pattern>] to cols={'like': <pattern>}
  • Changed filtering for rows from rows=[<keyword>, <value>] to rows={<keyword>: <value>}
  • Changed store.store_name to store.name
  • Changed table.exists to table.exists()

Enhancements:

  • Restoring snapshots no longer overwrites existing store or tables by default
    • Added errors parameter to adjust this behavior
  • Added table.name
  • Added is_connected()
  • Added store_exists()
  • Added database_exists()
  • Added table.partition_size read only property
  • Added table.repartition(new_partition_size) for re-partitioning a table to new_partition_size
  • Dropping both rows and cols in table.drop() at the same time is now supported
  • Added support for numpy datatypes in table.astype()
  • rows and cols arguments now supports more sequence types than just lists
  • before, after, and between is no longer invalid index values
  • like is no longer a invalid column name
  • table.read(rows=[...]) now raises an exception when rows are not found in the table
  • Improved table.insert() performance
  • Made some exceptions messages clearer

  • connect(<Database>) now correctly switches connection to <Database> instead of staying connected to the old database
  • Fixed append not working properly with default index
  • Fixed read_pandas not working with binary columns
  • Fixed read_pandas not working with large string columns
  • Fixed read_pandas not working with date32 and date64 columns

  • Fixed predicate filtering keeping one row to many in special cases
  • Fixed being able to write tables with non-string column names
