  • b5b3ffea   Implements index analysis features. ... Browse Dir » 
    There are 2 components:
Index Filter Analyzer : Part of DatabaseEnvironmentProvider, it gathers search filter statistics and displays the index filter, number of hits, max matching entries, and a message. Compound filters are broken down to their basic elements. f an index was not utilized while evaluating the search filter, max matching entries will be -1 and a diagnostic message will be included. The monitor entry also includes when the analyzer was enabled along with the number of total index and unindexed searches processed. 

Attribute Index Analysis, part of the dbtest tool. It cursors through all the indexes and finds the number of 100%, 95%, 90%, and 80% undefined index keys.  It also displays the value of the undefined keys along with the total number of keys in the index. The process is currently single threaded and might not scale to 10 mil+ DBs. However, this is currently unavoidable without the ability for JE to cursor through the records in log order.

    …or exiting of disks full.

Each instance of the monitor have two thresholds: "low" and "full". Other components can register their own handlers if they wish to receive notifications when the thresholds are reached. It extends the MonitorProvider interface and utilizes the update interval mechanism to poll the free disk space. The current free space and state of all monitor instances are exposed through the cn=monitor interface under the cn=Disk Space Monitor branch. The only component using the monitor now is the JE backend. When the "low" threshold is reached, write operations will only be permitted to users with the BYPASS_LOCKDOWN privilege. When the "full" threshold is reached, the backend is placed in read-only mode. The default "low" and "full" thresholds are 100 MB and 10MB respectively. Along with the new feature, this patch also added two privileges: SERVER_LOCKDOWN and BYPASS_LOCKDOWN. Any user with the SERVER_LOCKDOWN privilege can put and take the server out of lockdown mode. Any user with the BYPASS_LOCKDOWN mode can bypass lockdown mode. This was restricted to only "root" users before. In addition, the MonitorProvider abstract class no longer extends DirectoryThread. It now uses a static single threaded ScheduledExecutorService to update provider states. Any provider that wishes to have its state updated periodically needs to register its updater runnable with the scheduleUpdate method.

    replication server it will connect to. This also introduces a new 
(weighed) load balancing feature that spreads DS connections across the 
RSs, according to the RS weights defined by the administrator,

Issue 4343: https://opends.dev.java.net/issues/show_bug.cgi?id=4343

The commit includes necessary modifications for implementing what is 
described in this document:

https://www.opends.org/wiki/page/ReplicationServerSelection

There is a little "implementation" section in this document that 
explains some important stuff.

Also good to know for these code modifications:

- The topology info related to RSs and kept by the ReplicationBroker is 
now fully kept in a new map of a new ReplicationServerInfo bag class. 
This map is updated upon reception of a TopologyMsg.
- Protocol change: the TopologyMsg now includes the RS url in the RSInfo 
list
- The dynamic change of the weight of a RS triggers a new TopologyMsg 
being fired, to support dynamic change of weights and automatic topology 
re-connections
- SameGroupIdPoller thread has disappeared and its functionality is 
replaced by the mechanism that re-evaluates the more suitable RS (see 
section 5, in the document for more details)

  • c3c3cf15   In order to support a more clever algorithm for the DS to choose his RS, ... Browse Dir » 
    we introduce:



- a weigth, which is an integer affected to each RS that combined with 
each others will define a percentage value which matches the number of 
DSs (compared with total number od DSs in the topology) that can be 
connected to the RS at a time in the topology. In these modif, this 
configuration of the weight is added as well as dynamic changes. Also 
transported in Topo messages. No modification of the connection 
algorithm yet



- Also to support the future connection algorithm, these modifs 
introduces a Monitoring Publisher thread which is a thread that sens 
every 3 seconds a Monitoring message (unchanged format) to every DSs 
that are connected to him. These information will be used by the DSs to 
potentially reconnect to another RSs with a newer server state (info 
included in monitoring messages)



The new connection algorithm will take into account:

- group id

- generation id

- server states

- locality (same VM)

- weight (load)

  • 094b13bd   - Addition of ReplServerStartDSMsg now sent to a DS connecting to a RS ... Browse Dir » 
    in handshake phase instead of a ReplServerStartMsg. ReplServerStartDSMsg 
contains same thing as ReplServerStartMsg but also contains

  - replication server weight

  - number of ciurrently connected DS on the RS

  => both will be used for future new RS choice algorithm



- Addition of a StopMsg sent:

  - when any entity (DS,RS) is closing a connection (sent just before) 
with a peer

  - when DS finishes phase 1 of handshake (was gathering RS info for RS 
choice so sent just after new ReplServerStartDSMsg is received)

  => both are used to distinguish between a proper connection closure 
(no message) and an unexpected one (error log)



- Compatibility between protocol V4 and V3 (and before)

  - changed MonitorMsg to never be created with a protocol version

  - MonitorMsg now always sent with publish(msg, version) (publish 
method without version was used so bug)

  - TopologyMsg now always sent with publish(msg, version) (publish 
method without version was used so bug)
