Aerospike JDBC Configuration Parameters

The Aerospike JDBC driver can be configured through the JDBC connection URL. For example:

jdbc:aerospike:localhost/test?sendKey=true&durableDelete=true&expiration=-1

For detailed information about configuration properties, see the following sections.

Aerospike Java client configuration

The parameters need to match fields of the Aerospike Java client's Policy and its subclasses, which take String, int or boolean values.

The optional configuration parameters include the following

Param Default Description Aerospike Java Client
useBoolBin true Use the boolean data type Value.UseBoolBin
compress false Use zlib compression on commands to the server Policy.compress
connectTimeout 0 Socket connect timeout in milliseconds Policy.connectTimeout
loginTimeout 5000 Login timeout in milliseconds ClientPolicy.loginTimeout
tendInterval 1000 Interval in milliseconds between cluster tends ClientPolicy.tendInterval
timeout 1000 Cluster tend info call timeout in milliseconds ClientPolicy.timeout
totalTimeout 0 Total transaction timeout in milliseconds Policy.totalTimeout
useServicesAlternate false Use "services-alternate" instead of "services" for cluster tending ClientPolicy.useServicesAlternate
sendKey false Send user key on both reads and writes Policy.sendKey
durableDelete false If the transaction results in a record deletion, leave a tombstone for the record Policy.durableDelete
expiration 0 0 : use namespace default-ttl; -1: never expire; -2 don't change the ttl; otherwise seconds till expiration Policy.expiration

JDBC Driver configuration

The following parameters configure the internal state of the driver. Their default values are sufficient in most cases. Consider setting a custom value if really necessary.

Param Default Description
recordSetQueueCapacity 256 The capacity of the record queue for asynchronous Aerospike operations
recordSetTimeoutMs 1000 Timeout for the asynchronous queue write operation in milliseconds
metadataCacheTtlSeconds 3600 Database metadata cache TTL in seconds
schemaBuilderMaxRecords 1000 The number of records to be used to build the table schema
showRecordMetadata false Add record metadata columns (__digest, __ttl, __gen)
