This plugin extracts the following:

  • Metadata for indexes
  • Column types associated with each index field

CLI based Ingestion​

Install the Plugin​

The elasticsearch source works out of the box with acryl-datahub.

Starter Recipe​

Check out the following recipe to get started with ingestion! See below for full configuration options.

For general pointers on writing and running a recipe, see our main recipe guide.

source:
  type: "elasticsearch"
  config:
    # Coordinates
    host: 'localhost:9200'

    # Credentials
    username: user # optional
    password: pass # optional

    # SSL support
    use_ssl: False
    verify_certs: False
    ca_certs: "./path/ca.cert"
    client_cert: "./path/client.cert"
    client_key: "./path/client.key"
    ssl_assert_hostname: False
    ssl_assert_fingerprint: "./path/cert.fingerprint"

    # Options
    url_prefix: "" # optional url_prefix
    env: "PROD"
    index_pattern:
      allow: [".*some_index_name_pattern*"]
      deny: [".*skip_index_name_pattern*"]
    ingest_index_templates: False
    index_template_pattern:
      allow: [".*some_index_template_name_pattern*"]

Config Details​

Note that a . is used to denote nested fields in the YAML recipe.

FieldDescription
ca_certs
string
Path to a certificate authority (CA) certificate.
client_cert
string
Path to the file containing the private key and the certificate, or cert only if using client_key.
client_key
string
Path to the file containing the private key if using separate cert and key files.
host
string
The elastic search host URI.
Default: localhost:9200
ingest_index_templates
boolean
Ingests ES index templates if enabled.
Default: False
password
string
The password credential.
platform_instance
string
The instance of the platform that all assets produced by this recipe belong to. This should be unique within the platform. See https://datahubproject.io/docs/platform-instances/ for more details.
ssl_assert_fingerprint
string
Verify the supplied certificate fingerprint if not None.
ssl_assert_hostname
boolean
Use hostname verification if not False.
Default: False
url_prefix
string
There are cases where an enterprise would have multiple elastic search clusters. One way for them to manage is to have a single endpoint for all the elastic search clusters and use url_prefix for routing requests to different clusters.
Default:
use_ssl
boolean
Whether to use SSL for the connection or not.
Default: False
username
string
The username credential.
verify_certs
boolean
Whether to verify SSL certificates.
Default: False
env
string
The environment that all assets produced by this connector belong to
Default: PROD
collapse_urns
CollapseUrns
List of regex patterns to remove from the name of the URN. All of the indices before removal of URNs are considered as the same dataset. These are applied in order for each URN.
The main case where you would want to have multiple of these if the name where you are trying to remove suffix from have different formats.
e.g. ending with -YYYY-MM-DD as well as ending -epochtime would require you to have 2 regex patterns to remove the suffixes across all URNs.
collapse_urns.urns_suffix_regex
array
List of regex patterns to remove from the name of the URN. All of the indices before removal of URNs are considered as the same dataset. These are applied in order for each URN.
The main case where you would want to have multiple of these if the name where you are trying to remove suffix from have different formats.
e.g. ending with -YYYY-MM-DD as well as ending -epochtime would require you to have 2 regex patterns to remove the suffixes across all URNs.
collapse_urns.urns_suffix_regex.string
string
index_pattern
AllowDenyPattern
regex patterns for indexes to filter in ingestion.
Default: {'allow': ['.*'], 'deny': ['^_.*', '^ilm-history.*...
index_pattern.ignoreCase
boolean
Whether to ignore case sensitivity during pattern matching.
Default: True
index_pattern.allow
array
List of regex patterns to include in ingestion
Default: ['.*']
index_pattern.allow.string
string
index_pattern.deny
array
List of regex patterns to exclude from ingestion.
Default: []
index_pattern.deny.string
string
index_template_pattern
AllowDenyPattern
The regex patterns for filtering index templates to ingest.
Default: {'allow': ['.*'], 'deny': ['^_.*'], 'ignoreCase': ...
index_template_pattern.ignoreCase
boolean
Whether to ignore case sensitivity during pattern matching.
Default: True
index_template_pattern.allow
array
List of regex patterns to include in ingestion
Default: ['.*']
index_template_pattern.allow.string
string
index_template_pattern.deny
array
List of regex patterns to exclude from ingestion.
Default: []
index_template_pattern.deny.string
string
profiling
ElasticProfiling
Configs to ingest data profiles from ElasticSearch.
profiling.enabled
boolean
Whether to enable profiling for the elastic search source.
Default: False
profiling.operation_config
OperationConfig
Experimental feature. To specify operation configs.
profiling.operation_config.lower_freq_profile_enabled
boolean
Whether to do profiling at lower freq or not. This does not do any scheduling just adds additional checks to when not to run profiling.
Default: False
profiling.operation_config.profile_date_of_month
integer
Number between 1 to 31 for date of month (both inclusive). If not specified, defaults to Nothing and this field does not take affect.
profiling.operation_config.profile_day_of_week
integer
Number between 0 to 6 for day of week (both inclusive). 0 is Monday and 6 is Sunday. If not specified, defaults to Nothing and this field does not take affect.
