Syntax conventions Description
UPPERCASE Literal keyword.
Lowercase Not literal.
Italics Variable value. Replace with a valid option or user-defined value.
[ ] Optional. Square brackets ( [ ] ) surround optional command arguments. Do not type the square brackets.
( ) Group. Parentheses ( ( ) ) identify a group to choose from. Do not type the parentheses.
| Or. A vertical bar ( | ) separates alternative elements. Type any one of the elements. Do not type the vertical bar.
... Repeatable. An ellipsis ( ... ) indicates that you can repeat the syntax element as often as required.
'Literal string' Single quotation ( ' ) marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case.
{ key:value } Map collection. Braces ( { } ) enclose map collections or key value pairs. A colon separates the key and the value.
<datatype1,datatype2> Set, list, map, or tuple. Angle brackets ( < > ) enclose data types in a set, list, map, or tuple. Separate the data types with a comma.
cql_statement;End CQL statement. A semicolon ( ; ) terminates all CQL statements.
[ -- ] Separate the command line options from the command arguments with two hyphens ( -- ). This syntax is useful when arguments might be mistaken for command line options.
' <schema> ... </schema> ' Search CQL only: Single quotation marks ( ' ) surround an entire XML schema declaration.
@xml_entity='xml_entity_type' Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrconfig files.
keyspace_name.table_name
Required. The keyspace and table names of the search index. Keyspace and table names are case-sensitive. Enclose names that contain uppercase in double quotation marks.
For shard.set.cover.finder:
DYNAMIC
Use randomization in token range and endpoint selection for load balancing. Default.
STATIC
Requires load balanced client. Suitable for 8+ vnodes. The same query on a node uses the same token ranges and endpoints. Creates fewer token filters, more performant than DYNAMIC.
When shard.set.cover.finder=DYNAMIC, values for shard.shuffling.strategy:
HOST
Shards are selected based on the host that received the query.
QUERY
Shards are selected based on the query string.
HOST_QUERY
Shards are selected by host x query.
RANDOM
Suitable only for 8 or fewer vnodes. Different random set of shards are selected with each request (default).
SEED
Selects the same shard from one query to another.

Examples

To not use randomization to select token ranges and endpoints:

dsetool set_core_property demo.health_data shard.set.cover.finder=STATIC

To use default randomization to select token ranges and endpoints:

dsetool set_core_property demo.health_data shard.set.cover.finder=RANDOM
