Performance improvements

Contains performance improvements. Full release note will be available with v0.12 release

This release is NOT binary compatible with previous releases.

Major release with performance improvements for Segment.

This release is NOT backward binary compatible.

Random read performance is nearly 2x times now vs previous release for persistent databases.

New v0.11 - 270,000 random reads per second.

Old v0.10.9 - 144,000 random reads per second.

• #135 - Allow PureFunction to be used as function type.
• #136 - Prepare should accept function type param
• #137 - FunctionStores should be unique to database instances bug

• #144 - Strict types for Apply.scala in Java - Return.java
• #145 - Use java.lang.Void instead of Functions.Disabled
• #147 - Prepare range commit does not apply value to toKey bug
• #148 - Add range functions to Stream
• #149 - Implement Stream helper functions range & tabulate stream
• #81 - Implement Stream.collect. Contribution from @sh0hei

Resolves:

#128 - ZIO support - See examples

Resolved:

#127 - Monix support - See examples
#126 - Tag should be optionally supplied on DB creation.

Closed issues

• #125 - getOrFetchValue should recovery from CloseChannel failures
• #123 - Functions's serialisation should not be tied to keys
• #111 - registerFunction and applyFunction need to be more type-safe

Resolves:

• #122 - Deprecated Grouping
• #121 - Removed IO from lower level effectful functions
• #120 - Add terminateAndRecoverError to Actor
• #118 - Replace synchronised block in Map with Sequencer
• #116 - Re-order storage IDs so that the most used key-values get assigned ids with lowest byte size.
• #115 - functions should be optionally enabled so that cost of storing time is optional
• #114 - varInts should store as little endian for prefix compression
• #112 - Benchmark performance of Slice ++
• #109 - Segment file sizes are not consistent when grouping is specified in 0.9
• Other performance improvements.

Fixes issues

• #106 - Remove locks from PersistentMap and MemoryMap
• #105 - Improve compaction state change detection in levels when performing read seeks
• #107 - Compaction tests
• #110 - enabled extensions package
• Temporarily disables grouping in default configurations due to #109
• Simplifies Level seeks
• Removes getUnsafeState from WiredActor
• Implements ask for Actors

First ALPHA release for 0.9 (undergoing tests) focused on improving performance.

It implements :

• configurable BinarySearch, HashIndex & BloomFilter.
• compression at key-value, block & file/segment level.
• configurable IO strategies for controlling IO concurrency.
• Reduced IOps with blockCacheSize.
• caching can be completely disabled, partially enabled or fully enabled.
• support for custom containers with Tag[_].
• Implementation of new types - Actor, WiredActor, Scheduler, IO & IO.Defer.
• Uses Actor directly for caching.
• Improved Grouping strategies.
• write are also now asynchronous with Tag[_].
• Important: extensions package is temporarily disabled and will be enabled in the next release.
• There are few other changes that will be documented in 0.9-BETA.1's release notes.

#74 - Add alias for default method in KeyOrder.
