Upgrading existing clients

As Terrapipe 1.0 has reached EOL, all clients have to be upgraded to use the Skyhash 1.0 Protocol.

Upgrading existing datasets

Please refer to this wiki article.

Improvements in the new protocol (Skyhash)

• Upto 40% lower bandwidth requirements
• Upto 30% faster queries
• Support for recursive arrays
• More robust and well tested than Terrapipe

Internal codebase improvements

• BGSAVE is now tested by the test suite
• skysh and sky-bench both use the Rust client driver for Skytable.

Version 0.5.3 [2021-05-13]

No breaking changes

Fix persistence (see #150)

Version 0.5.2 [2021-05-07]

No breaking changes

• sky-bench is less agressive and runs sanity test before benchmarking
• skyd now locks the data file (the data.bin file)
• The data directory structure has been changed (see #144) (all files are now stored in ./data/*)
• Fixed 'Connection Forcibly Closed' errors on Windows (see #110)
• Add support for line-editing and keyboard shortcuts on skysh (see #142)
• Fixed problems while parsing snapshots in the snapshot directory (see #144)
• The old data directory structure has been deprecated (see #144)
• Official support for 32-bit platforms (see #139)
• Tier-2 Support for Linux musl (x86_64) (see #136, #135)

Version 0.5.1 [2021-03-17]

No breaking changes

• Built-in TLS/SSL support
• Custom host/port settings in sky-bench
• Mock keys can be created with sky-bench
• Security patch for VE/S/00001
• Escaping for spaces in skysh
• tdb is now called skyd (short for 'Skytable Daemon')

Version 0.5.0 [2020-11-19]

This release introduces breaking changes!

• Command line configuration added to tdb
• ⚠ Positional arguments in tsh and tdb-bench have been removed
• MKSNAP now has an enhanced version which enables snapshots to be created even if they're disabled on the server side
• If BGSAVE fails, no more writes will be accepted on the server side. All commands that try to modify data will return an internal server error
• tdb-bench now provides JSON output with the --json flag
• The Dockerfile was fixed to use command line arguments instead of the configuration file which caused problems
• The enabled key under the snapshots key in the configuration file has been removed

Upgrading

• Users who ran tsh like tsh 172.17.0.1 2003 will now need to run:

tsh -h 172.17.0.1 -p 2003

• Users who ran tdb-bench like tdb-bench 10 100000 4 will now need to run:

tdb-bench -c 10 -q 100000 -s 4

• To enable snapshots, you just have to add the key: there is no need for the enabled key. To disable snapshots, you just have to omit the snapshot key (block) from your configuration file

Version 0.4.5 [2020-10-29]

Version 0.4.1 [2020-09-06]

No breaking changes

This release adds support for configuration files

Version 0.4.0 [2020-08-30]

This release introduces breaking changes

• Actions added: MSET , MGET , MUPDATE

• Improved terminal output

Fixes:

• Explicit handling for incomplete responses in tsh

Migrating existing clients

The Terrapipe protocol was revised and promoted to 1.0. This will cause all existing client implementations to break, since the protocol has changed fundamentally. The clients have to implement the latest spec.

Version 0.3.2 [2020-08-07]

No breaking changes

The tsh component printed the wrong version number. This has been fixed.

Version 0.3.1 [2020-08-05]

This release introduces breaking changes

This release fixes #7, #8. It also adds several under-the-hood optimizations greatly improving query performance.

Migrating existing clients

The only significant change in the protocol is the new metalayout format: #a#b#c instead of the previously proposed a#b#c# .

Disk storage format

The disk storage format was changed rendering existing binary data files incompatible. However, if you have any existing data - which is important, open an issue - because we'll be able to provide a tool that can help you easily migrate your existing datasets - with a one line command - so - no worries!

Version 0.3.0 [2020-07-28] (⚠ EOL)

No breaking changes.

This version enables persistence for stored data

Version 0.2.0 [2020-07-27] (⚠ EOL)

This release introduces breaking changes

This release implements the latest version of the Terrapipe protocol.

Migrating existing clients

All clients have to reimplement the Terrapipe protocol to match the latest spec.

Version 0.1.0 [2020-07-17] (⚠ EOL)

This release provides an experimental client and server implementation.
