35 * Rebalancing
36 - New better rebalancing support with (a) checkpointing (b) progress bar (c) support for RO store rebalancing
37 - Documentation - https://github.com/voldemort/voldemort/wiki/Voldemort-Rebalancing
38 - In the process solves Issue 203, 288, 305, 307, 311
39
40 * Client side changes
41 - Pipeline routed store ( with support for topology awareness ) - Changed the default client side routing
42 to use a state machine like system. More documentation - https://github.com/voldemort/voldemort/wiki/RoutedStore-redesign
43 - Lazy store client - Some of our clients are very inactive and don't really do many requests. For such
44 clients it doesn't make sense to bootstrap the metadata at startup. Hence from now onwards clients instantiated
45 from SocketStoreClientFactory give a LazyStoreClient which will not bootstrap till the first request is made
46 - Caching store client factory - We have also checked-in a new store client factory which we use internally
47 at LinkedIn to cache store clients for stores which we repeatedly.
48 - Failure detector - We have fixed some bugs in the ThresholdFailureDetector. This is an improvement over the naive
49 BannageFailureDetector which would aggressively mark nodes down after a single failure. More details -
50 https://github.com/voldemort/voldemort/wiki/Client-side-failure-detector-implementations
51 - Issue 219: StoreClient::put returns a Version - You may have to upgrade your clients since now the StoreClient returns
52 a version to be used in successive requests.
53
54 * Read-only store changes
55 - Admin based store swapper - Till 0.81 we relied on a servlet based fetcher / swapper.
56 Now we support an admin based store swapper which reports progress.
57 - Other changes - (a) New directory format (b) Two new data format. Support for iterating over read-only data
58 (c) Checksum of data in .metadata file (d) Some monitoring changes of RO stores
59
60 * Jar upgrades
61 - Introduction of JNA 3.2.7 - We have introduced JNA 3.2.7 in this release for supporting symbolic links in read-only stores.

85
3363fcc @afeinberg Updated release notes, set build version to 0.81
afeinberg authored Jun 16, 2010
86 Changes made since 0.80.2:
87
88 * IMPORTANT: we have upgraded the Hadoop Core jar to v0.20.2. Since
89 this version of Hadoop requires Java 6, in order to retain backwards
90 compatibility with Java 5, you will need to replace this jar with
91 the Hadoop 0.18.* core jar.
92 * Multiple donors for Voldemort Rebalancing: speeds up rebalancing, by
93 allowing a single stealer node to transfer partitions from multiple
94 nodes
95 * Features for EC2 Testing
96 * Read-only Stores: backwards compatibility with 0.70, bug fix in
97 Checksum code
98 * Hadoop InputFormat, Pig LoadFunc in Contrib: ability to perform
99 Map/Reduce (either directly via Hadoop or using Pig) over data in
100 Voldemort stores. See:
101 < contrib/hadoop/test/voldemort/hadoop/VoldemortWordCount.java > for
102 an example.
103 * Voldemort Performance Tool: performance measurement tool based on
104 YCSB (Yahoo Cloud Serving Benchmark) code. Run
105 < bin/voldemort-performance-tool.sh --help > for more information.
106 * Reverted default failure detector implementation back to
107 BannagedPeriodFailureDetector due to potential bugs in the
108 ThresholdFailureDetector

115 operations when the NIO connector is enabled)
116 * VoldemortAdminTool: Added support to specify stores, support to
117 fetch all keys to a binary file, support to save keys in ASCII
118 (JSON) format [experimental], capability to add stores. Run
119 < bin/voldemort-admin-tool.sh --help > for more information.
120 * Minor bug fixes for Rebalancing
121 * Issue 240: Voldemort fetcher should use different temp directories for
122 different stores
123 * Checksum capability during construction of Voldemort read-only stores

131 TresholdFailureDetector
132 * Fixed issue 222: Revised KeyedResourcePool.close(K key) to fix
133 leaking sockets
134 * Fixed issue 198: Revised ReadRepairer to use a separate copy of the
135 vector clock, fixing a situation where NoSuchElementException would
136 be thrown
137 * Miscellaneous enhancement: support for TCP keep-alives, improved
138 read only store utilities, command line interface to AdminClient,

141 Release 0.80 on 2/18/2010
142
143 Changes made since 0.70.1:
144
145 * IMPORTANT: backwards compatibility between the client and server has
146 changed. A backwards incompatibility in the wire protocol was found
147 between releases 0.60 to 0.70.1 and releases prior to 0.60. We chose
148 to make 0.80 compatible with 0.57.1 and earlier versions, while
149 introducing an incompatibility with 0.60-0.70.1. What this means is
150 that if you're presently running 0.60 and higher, you would need to
151 upgrade the Voldemort jar files on *all* servers and clients.
152 * Upgraded the BDB storage engine to use BerkeleyDB-JE 4.0.92,
153 retaining ability to use BerkeleyDB-JE 3.3.* if desired. IMPORTANT:
154 if one switches from BerkeleyDB-JE 3.3.* to 4.0.92 they will be able
155 to access all of existing data. Once a switch has been made to
156 4.0.92 the data will not be readable by earlier versions of BDB. If
157 there's a chance that a roll back to 3.3.* might be needed, the best
158 course of action will be to make a backup of existing data
159 prior to upgrading.
160 Switching between 3.3.* and 4.0.* would also require rebuilding the
161 class files (e.g., by running "ant clean && ant release" after
162 replacing the BDB jar files).
163 * Compression support for read-only stores
164 * Increased the socket buffer size for transferring read-only
165 stores from Hadoop for improved performance over high-latency links
166 * NIO support for the Admin Service, including Streaming
167 Functionality
168 * Support for adding stores on the fly via the Admin
169 Service
170 * Fixed issue 209: Incorrect object passed to List.contains in
171 RebalanceUtils.getLatestCluster()
172 * Fixed issue 211: Unnecessary read repairs during getAll() with more
173 than one key
174 * Other enhancements: better CLI for rebalancing, throttling in
175 Admin Service is now based on all disk activity

178
179 Changes made since 0.70:

182 undergoing rebalancing, proxyGetAll() would be called with an
183 empty list even if rebalancing wasn't happening

194 * Beta mechanism for restoring all of node's data from replicas on
195 demand. This is an alternative to a more gradual mechanism provided
196 by read-repair: useful when a machine is down for a prolonged period
197 and is then re-inserted into the cluster.
198 Invoked via JMX: the operation is restoreDataFromReplication in the
199 voldemort.server.VoldemortServer MBean, with a mandatory parameter
200 (integer >= 1) indicating the number of transfers to do in parallel.
201 * Simple gossip protocol (for cluster metadata) merged
202 into the main branch. Disabled by default: use "enable.gossip=true"
203 to enable, use "gossip.interval.ms" to set an interval at which gossip
204 occurs (default: 30000 i.e., 30 seconds).
