Andromeda 1.2.0

Changes:

• Explicitly settings DuckDB’s temp_directory to the Andromeda temp folder to avoid running out of space in an undefined temp location.

• Set default memory limit to 20% instead of 80% of system memory to avoid out-of-memory errors when there are multiple Andromeda objects in memory.

• flushAndromeda() now also evicts the cache by default, and is called after appending or creating a table from another Andromeda table.

• The length() and names() method no longer throw an error when the Andromeda object is no longer valid, but just return 0 and an empty vector, respectively. This is to avoid error messages caused by RStudio querying the object.

Andromeda 1.1.1

• Added flushAndromeda() function.

• Added andromedaThreads option to control the maximum number of threads Andromeda is allowed to use.

Bugfixes:

• Calling flushAndromeda() before copying entire Andromeda (copyAndromeda()) or just a table ([[]]<- operator) to avoid segfault.

• Switch from zip::unzip() to utils::unzip() to avoid ‘mtimes’ errors.

Andromeda 1.0.0

Andromeda 0.5.0

Changes

• Andromeda now supports dates and datetimes (link).

Bug Fixes

• Fix issue when loading loading large Andromeda files from disk (link).

Andromeda 0.4.1

Changes

• Added the createIndex, listIndices, and removeIndex functions.

Bug fixes

• Setting SQLite temp_store_directory to Andromeda temp folder as well to prevent running out of space in default drive.

Andromeda 0.3.1

Bug fixes

• Switching to low-level Java calls to avoid error in CRAN’s Debian test environment.

Andromeda 0.3.0

Changes

• Throw more informative error when user tries to use invalid Andromeda object.

• Added function getAndromedaTempDiskSpace. Requires rJava to be installed. (Returns NA if not installed.)

• Throw warning when disk space becomes low. Threshold defaults to 10GB, but can be altered using options(warnDiskSpaceThreshold = <n>).

• Allow assigning query result to an Andromeda table where the query uses that Andromeda table. (e.g. andromeda$cars <- andromeda$cars %>% filter(speed > 10))

• Added progressBar arguments to batchApply and groupApply.

Bug fixes

• Unzipping now also done in Andromeda temp folder (instead of system temp folder).

• Lower but faster compression level now also used when saving without maintaining connection.

Andromeda 0.2.0

Changes

• Dropping nrow and ncol support, as this seems to cause instability and is not consistent with dplyr.

• Dropping isSorted function, as database queries are only guaranteed to stay sorted if explicitly required to (using arrange).

• Added restoreDate and restorePosixct functions.

Bug fixes

• Fixed typo in isAndromeda function name.

• Fixed incompatibility issue with dplyr 1.0.0 causing ‘method not supported’ error.

Changes

• Adding fast isSorted function.

• Changes in documentation for CRAN.

Andromeda 0.1.1

Changes

• Minor edits to documentation in preparation for submission to CRAN.

• Changing compression level when saving: 10-fold reduction in compression time at the cost of 10% larger file size.

• Increasing batch size from 10,000 to 100,000 to increase speed.

• Turning of SQLIte journal to increase speed.

Andromeda 0.1.0

Initial version.
