Tiedot Versions Save

This is a maintenance release to fix various build issues discovered on ARM and Windows platforms, together with general performance improvements.

Bug fix:

• tiedot performs poorly on certain OS/FS combinations, this is due to the sparse file unintentionally created by Truncate operation, which is now fixed.

New experimental feature:

• Javascript Web Token can be optionally enabled to hand out token and authorize API calls.

Be aware that:

• This release gets rid of the web control panel due to numerous packaging/functional issues. Please let me know if you are interested in renovating the web control panel application!

Sorry - I messed up a file in 3.1.2. This release fixes it.

Improved RPM spec and systemd unit file to properly build on Open Build Service.

Error handling is easier in embedded usage, see example.go for more details.

Fix a bug which causes query processor to return incorrect intersection/complement result.

New stable features:

• A beautiful web control panel application runs along with ordinary HTTP APIs.
• Easily scan through large collections using new HTTP and embedded APIs.
• To package tiedot into RPM package, there is now a RPM spec pre-cooked for you.
• To run tiedot as a daemon, simply use the systemd user unit file.

Improvements:

• Significantly improved startup performance, thanks to Smart File Scan.
• Other improvements in error handling, locking, logging, and embedded usage examples.

Bug fix:

• Fix a bug that may cause inaccurate lookup query result to be returned.
• Fix a bug that may cause severely degraded performance in certain usages.

Bug fix:

• Fix numerous bugs that may cause inconsistent index state in version 2.x

Improvements:

• Move document ID out of document data itself, improving performance.
• Tweaked hash table initial parameters.

Be aware that:

• Version 3.0 is not compatible with older databases, unfortunately a migration tool is not available at the moment.

New experimental features:

• JSON parameterized queries
• A Python client for HTTP APIs

tiedot 2.0 brings to you new file structures, APIs and a much cleaner codebase. The essential new feature in 2.0 is that all collections are partitioned, hoping to show better scalability; but the mechanism is still being tweaked.

Unfortunately, it is not compatible with older 1.x databases.

Bug fix:

• Better embedded usage examples.
• Code comments rewritten to be more readable.

Improvements:

• Benchmark sample size is now configurable via CLI parameters.
• Structures inside array may now be indexed as well.
• New HTTP service endpoint to dump database while staying online.
• New HTTP service endpoint to flush all data buffers.
• Verbose log messages can be turned on/off.

Be aware that:

• Original V1 and V2 HTTP APIs have been removed, together with their documents.
• Old query processor (used by V1 and V2 APIs) has been removed.
