# Apache Impala

Revision 1 (11 October 2026) · Modeled snapshot · through 8 October 2026.

All figures are research-informed estimates of analytical activity. Significant errors may remain; decimal places do not imply measurement precision.

Layer: compute. Values cover the years in which this category appears in the public timeline. Absence is not proof of zero use.

## Names and inspection notes

### 2012: Cloudera Impala

Impala’s public beta arrived in October 2012 and queried text and SequenceFiles on HDFS. This 0.05% slice represents beta activity, not a measured adoption share; Parquet support follows in 2013.

### 2013–2014: Cloudera Impala

This category is shown in the compute layer.

### 2015–2026: Apache Impala

This category is shown in the compute layer.
