Bulk indexing tips for Elastic search and Cassandra River

Elastic Stack Elasticsearch
1

Hello,

I have been working on a cassandra river which triggers periodically and
indexes all data in a cassandra column family. The implementation for now
spawns 10 threads and processes 10k documents (with 13 columns)/thread.
The performance initially was very good. It indexed 1M documents in 10mins.
But after a 1hour, the indexing became very slow and it indexed around 8M
documents. I am trying to index a total of 50M documents.

I have attached a screenshot of the memory and CPU usage. What I noticed
was, a lot of merge threads spawned up which reduced the speed considerably:
"elasticsearch[Doppelganger][[prodinfo][1]: Lucene Merge Thread #329]"
daemon prio=10 tid=0x2a630000 nid=0x4c28 runnable [0x246bd000]

So, I believe this has to do with some configuration which I can tweak to
improve bulk indexing. I am running 1 node with 5 shared with 2GB of
ES_HEAP_SIZE and no replicas for now.

Shay mentioned some tips here:
https://groups.google.com/forum/?fromgroups=#!topic/elasticsearch/APWxRLrMOeU
in 2011.
Wanted to know if there are any bulk indexing performance improvements?

I am also using: bulk.execute().addListener() (async) in place of
bulk.execute().actionGet() (sync)

I am planning to share the cassandra-river as soon its achieves acceptable
performance.

You need to throttle bulk indexing, for example with
org.elasticsearch.action.bulk.BulkProcessor, in order to get stable feed
rate over long periods of time.

Check out JDBC river for an example:
https://github.com/jprante/elasticsearch-river-jdbc/blob/master/src/main/java/org/elasticsearch/river/jdbc/strategy/simple/SimpleRiverMouth.java

What is your document size? It is also valuable to measure bulk indexing
throughput in MB/sec. I can index up to 8 MB/sec on an average desktop
PC in a single node cluster (which is ~10-15.000 docs per sec for my doc
size).

Note, indexing speed can greatly be improved by fixing the slowest part
of the system first: the I/O subsystem. Fast disk arrays (RAID 0) or
even SSD devices help a lot.

I am new to elasticsearch and trying to learn how to integrate elasticsearch with cassandra.
Can you give me some pointers.

Thanks,

Hello,

I am new to elasticsearch. I am trying
use GitHub - eBay/cassandra-river: Cassandra river for Elastic search. plugin to store data to
cassandra.
I dont see the data in cassandra. My search queries are returning from the
elasticsearch.

Please advise.

Thanks,
Ashwini

Hi Ashwini,

A river works the other way around, it moves data from cassandra to
elasticsearch so that you can index it.
I wrote cassandra-river as a proof of concept and hacked up in few days.
Please feel free to file a bug or send a pull request.

Thanks,

I think this river index docs from cassandra to Elasticsearch.
Not the opposite.

Moving this to the ML.

Did you restart the node?
What are the 15 first lines of your node logs?

Hello,

Thanks for the reply. I might have some misconfiguration in the settings.

Version:
Elasticsearch : 0.90.5
Cassandra: 1.1.6
Cassandra River - GitHub - eBay/cassandra-river: Cassandra river for Elastic search. (latest)

I did the following steps

  1. Created an instance of cassandra
  2. Created keyspace test
  3. Created column_family
  4. Populated 10 records
    like this
    [default@test] SET users['bobbyjo']['full_name']='Robert Jones';

[default@test] SET users['bobbyjo']['email']='bobjones@gmail.com';

[default@test] SET users['bobbyjo']['state']='TX';

[default@test] SET users['bobbyjo']['gender']='M';

[default@test] SET users['bobbyjo']['birth_year']='1975';
5. Installed elasticsearch cassandra river plugin
6.curl -XPUT "http://:9200/_river/abc/_meta" -d'
{
"type" : "cassandra",
"cassandra" : {
"cluster_name" : "demo",
"keyspace" : "test",
"column_family" : "users",
"hosts" : ":9160"
},
"index" : {
"index" : "abc",
"type" : "cassandra"
}
}'

I still dont see the data being indexed in Elasticsearch, here is what I ran to look at it.
curl -XGET "http://:9200/abc/cassandra/_search" -d'
{
"query": {
"match_all": {

    }
}

}'
I also tried

curl -XGET "http://:9200/users/_search" -d'
{
"query": {
"match_all": {

    }
}

}'

Please advise.
