Method Detail

strictTraceId

public abstract CassandraStorage.Builder strictTraceId(boolean strictTraceId)

Specified by:

strictTraceId in class StorageComponent.Builder

searchEnabled

public abstract CassandraStorage.Builder searchEnabled(boolean searchEnabled)

Specified by:

searchEnabled in class StorageComponent.Builder

autocompleteKeys

public abstract CassandraStorage.Builder autocompleteKeys(List<String> autocompleteKeys)

Overrides:

autocompleteKeys in class StorageComponent.Builder

autocompleteTtl

public abstract CassandraStorage.Builder autocompleteTtl(int autocompleteTtl)

Overrides:

autocompleteTtl in class StorageComponent.Builder

autocompleteCardinality

public abstract CassandraStorage.Builder autocompleteCardinality(int autocompleteCardinality)

Overrides:

autocompleteCardinality in class StorageComponent.Builder

sessionFactory

public abstract CassandraStorage.Builder sessionFactory(CassandraStorage.SessionFactory sessionFactory)

Override to control how sessions are created.

keyspace

public abstract CassandraStorage.Builder keyspace(String keyspace)

Keyspace to store span and index data. Defaults to "zipkin3"

contactPoints

public abstract CassandraStorage.Builder contactPoints(String contactPoints)

Comma separated list of host addresses part of Cassandra cluster. You can also specify a custom port with 'host:port'. Defaults to localhost on port 9042 *

localDc

public abstract CassandraStorage.Builder localDc(@Nullable
                                                 String localDc)

Name of the datacenter that will be considered "local" for latency load balancing. When unset, load-balancing is round-robin.

maxConnections

public final CassandraStorage.Builder maxConnections(int maxConnections)

Max pooled connections per datacenter-local host. Defaults to 8

ensureSchema

public abstract CassandraStorage.Builder ensureSchema(boolean ensureSchema)

Ensures that schema exists, if enabled tries to execute script io.zipkin:zipkin-cassandra-core/cassandra-schema-cql3.txt. Defaults to true.

useSsl

public abstract CassandraStorage.Builder useSsl(boolean useSsl)

Use ssl for driver Defaults to false.

username

public abstract CassandraStorage.Builder username(@Nullable
                                                  String username)

Will throw an exception on startup if authentication fails. No default.

password

public abstract CassandraStorage.Builder password(@Nullable
                                                  String password)

Will throw an exception on startup if authentication fails. No default.

maxTraceCols

public abstract CassandraStorage.Builder maxTraceCols(int maxTraceCols)

Spans have multiple values for the same id. For example, a client and server contribute to the same span id. When searching for spans by id, the amount of results may be larger than the ids. This defines a threshold which accommodates this situation, without looking for an unbounded number of results.

indexFetchMultiplier

public abstract CassandraStorage.Builder indexFetchMultiplier(int indexFetchMultiplier)

How many more index rows to fetch than the user-supplied query limit. Defaults to 3.

Backend requests will request QueryRequest.limit() times this factor rows from Cassandra indexes in attempts to return QueryRequest.limit() traces.

Indexing in cassandra will usually have more rows than trace identifiers due to factors including table design and collection implementation. As there's no way to DISTINCT out duplicates server-side, this over-fetches client-side when indexFetchMultiplier > 1.

build

public abstract CassandraStorage build()

Specified by:

build in class StorageComponent.Builder
