Customizing automatic resource generation
YAML-formatted options to customize solrconfig.xml and schema.xml generation.
- auto_soft_commit_max_time
-
The maximum auto soft commit time in milliseconds.
- default_query_field
-
The schema field to use when no field is specified in queries.
- type_mapping_version
-
The Solr/Cassandra type mapping version.
- directory_factory_class
-
The class name of the directory factory.
- enable_string_copy_fields
-
Specify to enable generation of non-stored string copy fields for non-key text fields. Text data can be tokenized or non tokenized. The enable_string_copy fields is false by default. True creates a non-stored, non-tokenized copy field, so that you can have text both ways.
- exclude_columns
-
A comma-separated (CSV) list of columns to exclude.
- generate_docvalues_for_fields
-
Define the fields to automatically configure doc values in the generated schema. Specify '*' to add all possible fields:
or specify a comma-separated list of fields, for example:generate_docvalues_for_fields: '*' ## You can omit this parameter or not specify a value
generate_docvalues_for_fields: uuidfield, bigintfield
- include_columns
- A comma-separated (CSV) list of columns to include. Empty = includes all columns.
- index_merge_factor
-
The index merge factor.
- index_ram_buffer_size
-
The index ram buffer size in MB.
- lenient
- Ignore non-supported type columns and continue to generate resources, instead of erroring out when non-supported type columns are encountered. Default: false
- resource_generation_profiles
- To minimize index size, specify a CSV list of profiles to apply while
generating resources.
- spaceSavingAll - Applies all of the following options.
- spaceSavingNoTextfield - No TextFields. Use StrField instead.
- spaceSavingNoJoin - Do not index a hidden primary key field. Prevents joins across cores.
- spaceSavingSlowTriePrecision - Sets trie fields precisionStep to '0', allowing for greater space saving but slower querying.
resource_generation_profiles: spaceSavingNoTextfield, spaceSavingSlowTriePrecision
- rt
- Enable live indexing to increase indexing throughput. Enable live indexing
on only one Solr core per cluster.
rt=true
Example to customize the solrconfig.xml and YAML files
default_query_field: name
auto_soft_commit_max_time: 1000
generate_docvalues_for_fields: '*'
enable_string_copy_fields: false
Use the dsetool
command to create the core and customize the solrconfig
and schema generation. Use coreOptions to specify the YAML file, for
example:
dsetool create_core nhanes_ks.nhanes generateResources=true coreOptions=config.yaml
Example to create a core with live indexing on
dsetool
command to create the core and use
coreOptions to specify a YAML file that includes the rt:
true setting, for
example:dsetool create_core udt_ks.users generateResources=true reindex=true coreOptions=rt.yaml
where the contents of the rt.yaml are rt: true
You can verify that DSE Search created the solrconfig and schema by reading core resources
using dsetool
.
Example to create a core with encryption
You can enable encryption for a new core.
