Indexes & Dictionaries

Indexes API allows you to retrieve indexes, memory, and dictionaries for all tables across your Indexima cluster.

Please note that views don't have indexes, dictionaries, or memory footprints.

Retrieve indexes details

GET /api/monitor/get/indexes
Retrieve all indexes in your Indexima cluster.
Example:

CODE

curl http://myindeximacluster:8082/api/monitor/get/indexes \
  -H "Authorization: $ACCESS_TOKEN" \
  -H "Monitor-Target-Host: indexima-core-1" \
  -H "Monitor-Target-Port: 9999" \
  --compressed -s

Reply JSON Format:

Name	Type	Description
schemas.schema	String	The schema name
schemas.tables.name	String	The table name
schemas.tables.dico	Integer	The dictionaries memory size in bytes
schemas.tables.indexes.name	String	The index name
schemas.tables.indexes.count	Integer	The index number of rows
schemas.tables.indexes.size	Integer	The index memory size in bytes
schemas.tables.indexes.main	Boolean	If this index contains all the table columns (called a “main” index)

Retrieve memory used for each index

GET /api/monitor/get/memory

Retrieve the memory used for all tables on each node of your cluster. This request is equivalent to executing a SHOW MEMORY ALL SQL command.

Example:

CODE

curl http://myindeximacluster:8082/api/monitor/get/memory \
  -H "Authorization: $ACCESS_TOKEN" \
  -H "Monitor-Target-Host: indexima-core-1" \
  -H "Monitor-Target-Port: 9999" \
  --compressed

Memory is represented by a tree structure with the following path :
Name of the node -> Schema -> Table -> Index

Name	Type	Description
loaded	Boolean	true if the current index is loaded in memory
dictionary	Integer	The dictionaries memory size, in bytes
size	Integer	The index memory size, in bytes
count	Integer	This index number of lines
bucketsize	Integer	The bucket disk size
isLimited	Boolean	true if the parent table is a limited table
isOnError	Boolean	true if this index is on error and can't be used
isDimension	Boolean	true if the parent table is a dimension table
isExternal	Boolean	true if the parent table is an external table
isTemporary	Boolean	true if the parent table is a temporary table

Retrieve dictionaries details

GET /api/monitor/get/dictionaries

Retrieve the dictionary details used for all tables on each node of your cluster. This request is equivalent to executing a SHOW DICTIONARIES ALL SQL command.

Example:

CODE

curl http://myindeximacluster:8082/api/monitor/get/dictionaries \
  -H "Authorization: $ACCESS_TOKEN" \
  -H "Monitor-Target-Host: indexima-core-1" \
  -H "Monitor-Target-Port: 9999" \
  --compressed

Dictionary is represented by a tree structure with the following path :
Name of the node -> Schema -> Table -> Dictionary field or expression

Two structures are sent :

Total memory and lines count, by node
Details for each table on each node

Name	Type	Description
size	Integer	The dictionary memory size, in bytes
count	Integer	The dictionary number of words
loaded	Boolean	true is this dictionary is currently in memory
