[infinispan-issues] [JBoss JIRA] (ISPN-3173) Define a new query operation over hotrod

[ https://issues.jboss.org/browse/ISPN-3173?page=com.atlassian.jira.plugin.... ] Mircea Markus updated ISPN-3173: -------------------------------- Description: Add a new query predicated to the [Hot Rod Protocol | https://docs.jboss.org/author/display/ISPN/Hot+Rod+Protocol+-+Version+1.2]. For now this operation should send an byte[] (the query encoded) over the network and receive an byte[] as response. The query and the result might get further specified in the future. This will be used by ISPN-3175 to implement the initial remote querying functionality the java hotrod client. was: HR request: [op_id] [payload]. The request payload is query specific (not defined in the HR protocol) and at this stage has the following format: [Q_TYPE] [QUERY_ST] [FIRST_INDEX] [PAGE_SIZE]. This format accommodates the remote query requirements as defined in ISPN-3169. - Q_TYPE (protobuf's byte) and query identifier, 1 for JPAQL (this is the query type we'll support). In future we'll add different query types as well. - QUERY_STRING (protobuf's string)- JPAQL string generated by the fluent API (ISPN-3169). Parameters are encoded in this string (vs being sent separately) - FIRST_INDEX + PAGE_SIZE (protobuf's int)- used for paginating/iterating over the result set. HR response: [HR_SUCESS_FLAG] [payload] PAYLOAD = [NUM_EL] [PROJ_SIZE] [ELEMENTS] - even though at this stage we don't support projections (see ISPN-3169) PROJ_SIZE is added for future compatibility when projection will be supported. Note that the payload for both request and response should be marshalled with protobuf as this information is read/written over multiple clients. -- This message is automatically generated by JIRA.
