into shards

How many instances?

The index size will be about the same as the

corpus of source documents

• Double this if you are deploying an index replica

Size based on storage requirements

• Either local storage or 512GB of Amazon Elastic

Block Store (EBS) per instance

• Example: 2TB corpus will need 8 instances– Assuming a replica and using EBS

– With i2.2xlarge nodes using 1.6TB ephemeral storage, 4 nodes would be enough

Best practices

Data nodes = Storage needed/Storage per node

Use GP2 EBS volumes

Use 3 dedicated master nodes for production deployments

Enable zone awareness

Set indices.fielddata.cache.size = 40

Best practices

Use smaller buffer sizes to increase throughput, but be

careful of concurrency

Use index rotation based on sizing

Default: stream limits: 2,000 transactions/second, 5,000

records/second, and 5 MB/second

Upload template and data

Number of shards = index size/30GB

Define the number of shards

when you create the index

Less is more

Writes occupy 1 shard, reads

occupy all shards

Mapping controls how data is indexed

not_analyzed text is best for

Kibana visualizations

Define a _template to

apply to all new indexes

The template also defines the

number of shards

0 delete 1,3,5

1 get 2,3,4,6

2 head 1,7,9

Send_data method

Demo: upload template, send

logs to Firehose

Best practices

• Use a template for settings

• Set number of shards based on 30 GB per shard

• Best case, 1 active shard per node

• For analysis use cases, set not_analyzed on all fields

Analyze Apache web logs

Amazon ES aggregations

Buckets – a collection of documents meeting some criterion

Metrics – calculations on the content of buckets

Bucket: time

Metr

ic: count

Best practices

Make sure that your fields are not_analyzed

Visualizations are based on buckets/metrics

Use a histogram on the x-axis first, then sub-aggregate
